Drilling in glass, tile or ceramic? These special drills make what can be a tough project easy and worry-free. Ensure very smooth, accurate, worry-free drilling in glass, tile or stone with our precision machined, 4-flute carbide-tipped bits. The 4-flute spear point starts more easily and stably than simpler drills. The entire drill bit is coated with titanium nitride to reduce wear. Use water as a lubricant and to control heat build-up if the hole is large or deep.
The boxed Basic Set includes sizes 5, 10, 12, 16 and 18 mm (approximately 3/16, 3/8, 1/2, 5/8, and 3/4 inch - metric sizes are generally adequate for glass or tile holes as they do not need to be exact.) The shanks will fit in a 3/8” chuck. These are highly recommended for Pros and DIY’ers. We were very impressed with our tests.
If you intend to use them for hanging pictures, we recommend you add the Supplementary Set sized 6, 7, & 8 mm to allow easy insertion of the small wall anchors. In fractional inches these correspond to just under 1/4”, just over 1/4” and 5/16”.
