I have both a normal Bosch Professional GSR 12V-15 Cordless Drill and the FlexiClick version Bosch GSR 12V-15 FC. I must admit the FlexiClick system simply grows on you because of its versatility.
Bosch PT Fan, came with a Bosch GSR12V-15 tool-modding video on its YouTube channel. In this article I will briefly describe the different steps to convert the normal GSR into a FlexiClick version.

How to convert Bosch Professional GSR 12V-15 into FC FlexiClick version
A little while a I purchased a complete Bosch Professional GSR 12V-15 FC set for a very good price-point at online retailer Toolstation. I must admit that more often I pick-up the FlexiClick than the normal Bosch GSR 12V. The reason is simple, the variety of task (also in hard to reach places) is endless.
The versatility of the Bosch Professional GSR 12V-15 FC somehow reminded me of the oscillating multi-tool and “problem-solver” Fein Multimaster. This is also on of the tools I would immediately replace. After seeing the Bosch PT Fan video I decided to convert the normal Bosch GSR 12V-15 into a FlexiClick version.
Bosch GSR 12V-15 FlexiClick Conversion Requirements
In order to successfully convert the Bosch GSR 12V-15 you need to purchase a spare part and two tools. If you start this tool-modding, I think you will probably own these tools already.
- Purchase part #45 from the Bosch Powertools After Sales Service exploded view, which has part number 1 600 A00 9AN. The retail price is about +/- EUR 30,– excluding VAT and I’ve bought the service part at Frabe Onderdelen Centrum
- Purchase a 50 mm Torx #9 bit (or screwdriver), if you don’t have one;
- Purchase a small flat head bit or -screwdriver, if you don’t have one (which I hardly doubt);
Step by step plan to convert Bosch GSR 12V-15 into FlexiClick version
With the proper tools and spare part #45 it takes 5 steps to disassemble the Bosch GSR 12V-15 and another 5 steps to reassemble to Bosch Professional tool and enjoy the FlexiClick options. In other words step 6-10 are more or less the reverse order of steps 1-5.
Disassembly Bosch Professional GSR 12V-15
- Carefully unscrew the 8 Torx #9 bolts (with part-number 101) that fit both housing-halfs of the Bosch Professional GSR 12V-15 Cordless Drill together;
- Carefully remove the clip (with part number 70) at the entrance of the battery. Removing is simple with a small flat head screwdriver;
- Remove one of the housing-halfs, and you can see the internals of the machine now;
- Remove the red speed control button on the top;
- Carefully remove the slip clutch unit with drill head of the Bosch Professional GSR 12V-15 Cordless Drill;
Re-assembly Bosch Professional GSR 12V-15
- Take the FlexiClick slip clutch unit part #45 and carefully insert it onto the drill engine. Please make sure that the black spring is on top of the machine;
- Slide the red speed control button in its place again, and make sure the button hooks onto the black spring of the slip clutch unit with part #45. Without properly installed you can’t switch speeds;
- Place the housing-half back on its place;
- Carefully insert the clip (with part number 70) at the entrance of the battery;
- Carefully tighten the 8 Torx #9 bolts (with part-number 101) that fit both housing-halfs of the Bosch Professional GSR 12V-15 Cordless Drill together;
Welcome to your converted FlexiClick version Bosch Professional GSR 12V-15 FC. 🙂
Concluding thoughts and wrap-up
I’m a huge fan of the Bosch Professional GSR 12V-15 FlexiClick, and while the normal 12V cordless drill is good the FlexiClick version is more versatile.
Please note that with modifying your machine you probably void warranty, or you should be aware that this is a possibility. For the price-point that I’ve purchased the Bosch GSR 12V-15 I’m willing to take that risk. 🙂 With a new tool I probably wouldn’t advise the modding.
The retail price of part number 1 600 A00 9AN is about +/- EUR 30,– excluding VAT (on-top of GSR 12V-15 price). I can fully utilize the various FlexClick heads having two Bosch Professional GSR 12V-15 FC cordless drills.
Would you modify a Bosch Professional tool ?
