Bosch GSR18V-EC FC2 FlexiClick Drill and 18v 4.0 AH Wireless Battery Review

An essential tool for use in the shop is some sort of drilling device. In the old days a brace or  "egg beater" drill would suffice. Nowadays they have been supplanted by cordless drills. I needed an extra cordless drill for the shop as sometimes you need a few drills setup to do different tasks (drilling, countersinking, screwdriving) so I thought I would have a look at the Bosch range.

I already have several Bosch Blue Professional tools and seem to have bought into the LBoxx systainer storage system. If you are into Festool or Dewalt of course you may have gone down their respective storage routes.

The Bosch Professional 18 volt family is wide ranging, Drywall screwdrivers, impact (percushion) tools, hand held circular saws, jigsaws, impact drivers/wrenches, combination tools and of course handheld drills.

The Bosch GSR18V-EC is part of the Bosch Professional 18V family and has a powerful EC brushless motor. It also has the "FlexiClick" system enabling it to take a range of interchangeable tool holders.

In its basic form it comprises a hex tool holder 


It also comes with a 13mm (1/2") Auto-Lock chuck. No tools are needed for the latter like most drill chucks these days.

The brushless motor gives a long life and low battery drain. The drill was supplied in an L-Boxx 136 with internal moulded dividers.



The drill has the usual controls

  • 2 speed Gear control Low/High
  • Direction rotation clockwise/anti-clockwise (counter-clockwise US)
  • 18 position torque setting
  • Battery charge condition
  • Bright LED illumination

So nothing new there as most drills today have those features.

Other features

  • Tool belt clip. The manual says this can also be used to hang the tool from a ladder - although I haven't yet tried that feature out!
  • Replaceable colour clips for easy labelling and identification of the tool - I don't think I will use that feature as I currently only have one of these!
  • Mountable bit holder for easy transport and storage of bits on the tool - useful I think.
  • Electronic Motor Protection (EMP) protects the motor against overload - a good feature.
  • Bosch Electronic Cell Protection (ECP) which protects the battery against overload, overheating and deep discharge - a great feature. 
  • Kickback control. When drilling large diameter holes wen you emerge on the other side of might hit an embedded nail this will prevent the drill from snatching from your hands and kicking back. I think this is a great safety feature that I've not seen on other cordless drills.
  • Very compact head length (173mm or 6-7/8" long) but still retains high power - it is surprising how short the tool actually can be with immense power reserves.

Battery packs

There is a large range of Lithium Ion batteries are available, wired and wireless so you can choose the best one for your needs.
There wasn't a battery supplied in this kit and there is a wide range to suit all tastes.

I decided to buy the wireless charger and the new 4.0AH CoolPack wireless battery. This is promoted by Bosch as being the "Worlds first wireless charging battery". I think they left out "system on a power tool" on their promotion material. Now I'm not sure of that claim as I've been using a wireless charging (Braun Oral B) toothbrush for years now and some mobile phones can also be charged wirelessly! I think it is a matter of time before all major manufacturers give the option of wireless charging. At the time of this writing this blog (May 2017) neither Festool, Makita, Milwaukee, Portacable nor Dewalt have a wireless charging option. I haven't checked any other brands yet.

The battery also has a bush button "charge left" indicator. This is 3 LEDs that light up according to how much charge is left. This can be seen on the phot above just below the BOSCH logo and lettering.
The battery itself is an induction charged device and simply is placed atop the induction charger GAL 1830 which I also bought. The battery can still be mounted on the tool so simply placing the drill on to the charger works well. The battery slides into place onto the toolwith a satisfying click. I placed the whole drill on charge for about 45 minutes before using it the first time.


Accessories

There are a range of attachments that you can purchase separately.

  • Right angle drill adapter
  • SDS rotary hammer adapter
  • Offset drilling adapter


From the 3 extra accessories I can see the offset drilling adapter to be very useful especially when fitting drawer slides. This adapter enables drilling very close to internal edges and walls. That might be a future purchase for TMc Woodworks.


The right angle adapter enables drilling at 90 degrees to the axis of the drill motor. Again great for drilling/screwing in confined spaces.




I can't really think that the SDS adapter would be any use for me as I already have a corded SDS drill. I suppose if you are up a ladder trying to drill holes in brickwork then it may be ideal for you. It will drill deep holes up to 10mm (3/8") diameter into concrete.



In use


I have had this a short time now and find that it is very comfortable to use, relatively lightweight, has masses of power and torque. It is far better than any of the battery drills I've used or still own. Drilling large holes in wood does not faze this drill. A comparison to my older drills is that the Makita would definitely bog down when drilling larger holes. The Bosch on the other hand just carries on with no changing in motor pitch.

The adjustable torque control is excellent. I've found when drilling through 3/8" holes in wood results in a relatively clean exit hole (without any backing). Of course my drills are all newly sharpened and the torque control was set to 6. When the bit broke through the clutch slipped and I found the bit hadn't gone fully through. Another slight squeeze of the trigger resulted in the bit slowly exiting the hole and very little fibre tearing. Obviously if drilling holes in furniture always have a backing board to ensure a clean exit hole.

The gearing is very smooth and the change from low speed to high speed is via a sliding switch. The drill did need to be stationary when changing gear.

Charging was a revelation. The charger can be remove from its carrier and placed on a bench, inset into a bench, works through thin acrylic or glass (so could be built into bench or charging station, doesn't get warm and is quick charging.
I don't think I'll go back to conventional chargers after trying this one out.

The LED light stays on for a few seconds after letting go of the trigger and is angled to illuminate the drill bit. Nothing different there from most other modern battery drills.

The belt clip would hold onto my belt but I don't think I would make much use of it.

The downside
I also found that fitting the bit holder to handle stopped the drill from sitting properly into the L-Boxx systainer. I removed the bit holder.

Colour coding the back of the drill is possible with the supplied plastic inserts but I found that pointless. If I had about 4 of these drills it might make more sense but I still don't think I would use colour coding.

Changing the chuck for other tools is very easy and quick. The drill body can be used on its own with screwdriver bits. There is a positive locking 1/4" holder built in.

Conclusion

There is nothing unusual in the operation of this drill as it is just that - a drill. However the addition of the optional attachments make it an attractive offering.
The main reason for buying this was to try out the wireless charging battery. It is excellent and make the drill a worthwhile investment. There are currently high capacity versions of the battery available (up to 6Ah) and Bosch is expanding the range of tools that can use the wireless batteries.
If you still have a conventional contact charged battery in a recent Bosch blue tool then you can change over to wireless as they are compatible. Check out the Bosch website to ensure beforehand though.

The rising price of old woodworking tools

I get occasional emails in my inbox from online dealers of second hand or pre-owned tools. I'm mainly interested in woodworking tools but these dealers also have tools from other crafts.
A couple of years ago (2015) the price of these were acceptable but due to the popularity driven by woodworkers to get hold of, for instance, old Stanley or Record hand tools the prices in the UK in 2017 are rocketing. A real case of  supply  and demand dictating the prices.
Now some of the lesser used tools are at the point of being the same or more than their modern day brand new premium tools like Lie Nielsen or Veritas (assuming that LN and LV are producing their version of those models). I recognise that dealers still have overheads to run their websites, have warehousing costs, wages to pay etc so they do have a mark up.
I have a fair selection of tools, old and modern (bought in the "golden age" of buying a few short years back) so I no longer have the need to collect. However if I was in the market for a speciality plane like a #95 Edge Plane (not that I am BTW ) I think I would buy a new Lie Nielsen one rather than spend more on a vintage Stanley. I don't think I would use the Stanley, instead treating it with reverence and it would end up in a display cabinet. Of course if that is what you want to do then go ahead. I like to use tools for what they were designed for - work.

That's not to say there are no bargains left to pick up. There are other websites where individuals can still sell their grandfathers rusting #4s and old chisels for a few bucks. Craigslist and Preloved both spring to mind. eBay of course can be a nightmare as you have to bid against somebody else (unless it has a fixed Buy It Now price) and may end up paying more than you should.

So if you are in the market for relatively cheap pre-owned tools best to scour sites like the latter mentioned, yard sales or flea markets rather than going to a dealer.

Tracksaw setting gauge

For all you users of tracksaws (Festool, Bosch, Makita etc) here is a design of a measuring gauge to make setting cuts far easier.

The one problem with cutting sheetgoods using a tracksaw is measuring. You create a good edge from stock by cutting about 1/8" off. Then using a tape measure and a pencil make a couple of pencil marks relative to this edge.
Then you set the tracksaw track onto the pencil marks and suddenly you can't see them. You move the track a little to expose the pencil line. Go to the other end and find that pencil line is 1/8" away from the rubber splinter guard. You move it back to the line, goto the other end and find you have obscured the pencil again.

This scenario does happen and sometimes you end up with a board cut that is slightly out of parallel and oversize because you covered the pencil line. There must be an easier way of setting this.
The good news is there is.

Steve Maskery of Workshop Essentials designed a simple setting gauge with integral rule that compensates for the track width and results in parallel, accurate width, repeatable cuts every time.
I take no credit for designing this but set about making one.
(Steve also says this has probably been done many times before in the dim and distant past but he was the first person to show it being created on video.)

Here is my Sketchup version of Steve's original design
Tracksaw Gauge Head


Stock

First of all I found a length of hardwood on my shelves around 1.2m (48") long. I milled this square to about 20mm (approx 3/4"). It is not essential that this is dead straight over its length and a slight about of bow is acceptable. If you can make it straight and it maintains then all the better.
Cut both ends square.
Relieve the arris on each side of the stock to remove any sharp edges and splinters.

Head fabrication

Next the head was made from a length of walnut cut to 20 x 30 x 90 mm (3/4" x 1-1/4" x 3-1/2").
I cut 2 blocks 20 x 30 x 35mm long (3/4" x 1-1/4" x 1-3/8") from walnut. Into one of these I drilled and tapped a hole for M6 (1/4" threads can be used in US). I also counterbored one end 12mm diameter x 10mm deep (1/2" x 3/8").

The walnut blocks were then glued on with a 20mm division to form a U section. I used the actual hardwood bar to space the blocks. There can be a slight amount of clearance here of about 10 thousands to allow the bar to slide easily back and forth. I further dowelled these blocks into place.

Graticule plate

Next an acrylic graticule was made from some 6mm (1/4") perspex or plexiglass I had in stock. It measures 30 x 90 x 6mm (1-1/4" x 3-1/2" x 1/4" thick) I scratched a line on the backside and highlighted it with a Sharpy to make it standout. Then I drilled 4 small holes, 1 in each corner, and countersunk them on the opposite face to the scratched line.

Then using small countersunk screws the transparent graticule plate was attached, line side down, across the blocks. All corners were then chamfered on my disc sander. I decided to radius 2 corners as a visual reminder as to which way around the reference face goes.

Assembly

Use a finger screw or machine bolt if you don't have one and insert it into the threaded hole. I found a plastic rod of suitable diameter and cut it to 8mm (5/16") long. This is the pressure washer to prevent marring the stock in use.



Then insert the stock and set it to a random length.

Calibration
The final part is calibrating the gauge. At this stage there is no scale on the gauge.

Take a random sheet from your racks and set it flat on your cutting bench. Cut one edge with your tracksaw to establish a straight edge. Then move the track over to the other edge of the board. Take your gauge and set the head to register on the straight edge, extend the stock until it touches the back edge of the track and lock the head in position.
Move the gauge to the other end of the track and ensure the track also is located correctly. 




Move the gauge back to the original location to ensure it hasn't moved.
 If you have track clamps lock them into place. The rubber strips on the underside of the track hold it into place 99% of the time but there is the odd time where you can knock it yourself.

Then make the cut with your tracksaw. Note that you have NOT measured anything whatsoever yet.


Remove the track saw and track.
Next using your most accurate steel rule take a measurement of the width of the board you have just cut. Make a note of this.

Applying the measuring tape.

You can buy self adhesive metal measuring tape that is intended just for this purpose. I bought one which came on a roll starting at 0mm and ending at 1000mm (0-39" approx). The ends of the tape have a large un-etched section intended for trimming to any size you wish. I bought one that works from right to left. You can also buy them that start from left and increase as you get to the right as shown below.



The tape is thin enough to slide underneath the graticule plate and between the face of the stock. Slide it into place and set it so the measurement you took is under the scratch line. Then using a few strips of blue tape temporarily stick the tape into place so it can't move. Remove the head.

Next cut the tape with tin shears to be shy of the end face. Now remove a small portion of the backing release paper and start sticking the tape down to the stock. Pull out the backing paper at 90 degrees to the tape whilst smoothing the tape as you go along. When you reach the first bit of blue tape remove it before carrying on. Do this until the entire tape is stuck down.

Using the tin shears again cut off the end that it surplus.

You will then have a gauge that starts at 127mm (5") or whatever the width of your track is.

My completed full length gauge


Reassemble the head into place and make a test cut this time setting the gauge to a determined length.

Measure the resultant board width and you will find it is spot on. If it isn't you can slot the holes in the graticule plate and move the scratch line slightly.

Improvements

You can put a brass threaded bush in the hole if you like but I haven't found it necessary

The French Cleat

A French cleat is basically a length of timber cut with a 45 degree bevel on its top edge. This cleat is screwed to a wall using whatever means you have at your disposal. Then you secure a corresponding cleat that is upside down with the bevel facing the item you wish to hang.
Then the cleat on your item simple is mated to the cleat on the wall and you have a strong connection to the wall. If you wish to move the item along the cleat simply lift and slide to position and let it mate back on place again.
