They are not intended for use on wood, metal, or masonry materials. For best results when drilling glass or stone, use slow rotary speeds and apply a small amount of water as a coolant to keep the bit and workpiece from overheating.\u003c\/p\u003e\n\u003ch4\u003eQ: What rotary tools are compatible with the 2.35mm shank?\u003c\/h4\u003e\n\u003cp\u003eA: The 2.35mm shank is a standard size that fits most hobby rotary tools including Dremel-style handpieces, flexible shaft machines, and pin vise drills. If your rotary tool uses a different collet size, a 2.35mm collet adapter may be required.
