Tradesman's Mate Tile/Ceramic High Hardness Drill Bits.

The Tradesmans Mate Offset Cutting Edge Tile Drill Bits are built for high-precision dry drilling in tough materials like tile, porcelain, marble, ceramic, and concrete. Featuring a unique eccentric cutting design, each bit alternates between two cutting edges on one side and a single edge on the other—delivering the stability of a cross drill with the sharpness of a single-edge bit. This innovative design ensures smoother holes, reduced cracking, and improved accuracy.

Ideal for low-speed, dry drilling applications, especially in situations where water cooling isn’t practical (such as overhead drilling), these bits provide reliable performance when working in confined or vertical spaces. With a hex shank, they are compatible with a wide range of power tools including hand drills, impact drivers, and bench drills. Available in individual sizes—6mm, 8mm, 10mm, 12mm, and 14mm—each drill bit has a total length of 90mm and a maximum drilling depth of 50.8mm, giving you flexible options to suit your specific project needs.
