![]() I found that the "tool place" in Kamloops had pretty good bits and a good range of sizes for about $20 each (for the 2.5" I bought). As for the rig.... I just drilled a piece of acrylic sheet first, then clamped on the glass to hold the bit in place for the first while.
A real good drill is the only needed expensive part. You need one with very fine control over the speed. You can always have your cheap bit re-coated if you actually wear it out. But you have to drill a lot for that to happen. |
