Rated 1 out of 5 by from Very difficult to use with an extremely short life I have almost nothing good to say about the Bosch GT600 drill bit. It is easy to start a hole with a brand new bit, but very difficult and time consuming to actually drill a complete hole in the side of a normal glass block! For one thing, the bit’s instructions don’t give any guidance about water at all. We had 26 glass blocks to drill for a craft project and went through 3 of these bits during 22 attempts with 4 blocks cracking for us. If the hole completes, the drill becomes VERY difficult to control. We needed a safety board to help catch the chuck (with a 3 / 4" hole in it to provide just enough clearance for the bit and spraying water) to prevent crashing into the glass when the cut finished. We tried using a lot of water, very little, or none. We tried using different drills, one a variable speed 0 – 2500 RPM and the other drill set in low gear ratio with 0 – 1,000 RPM and both had similar results. You could get 1 or 2 good holes out of a bit if you were lucky (taking a little under 2 minutes with a fresh bit), and then it dulled and was very slow at best or shot altogether. Also, the edges of the holes were often fairly uneven and sharp.Based on some videos I found online of similar bits, I think using one of these in a drill press with precise speed control, perfect vertical alignment, plenty of water and a fixed depth stop might work- BUT for some bizarre reason Bosch’s instructions explicitly say NOT to use a drill press!We found that using a hole saw style diamond bit was MUCH easier and faster.
