This collection features high-quality products carefully selected for our customers. Browse our selection to find exactly what you're looking for.

Match the bit to your material and setup for faster, cleaner holes. Wax-filled dry bits excel when water isn’t practical; electroplated or vacuum-brazed bits offer longer life and cooler cutting (use water when possible). Prevent walking on glossy tile with a suction-cup drill guide, start at a slight angle, then square up after the bit bites. Run low RPM, no hammer mode, and steady feed to reduce heat and micro-chips—pulse the cut and cool between passes on dense porcelain. Support glass mosaics and keep the cut wet for best results. Choose the correct diameter for anchors and fittings, and confirm your shank/arbor (5/8"-11, M14, hex) to fit drills or grinders. Explore our range from ¼" to 2"+ plus guides and adapters—curated for tile pros who need reliable, repeatable performance.
