15-Piece Diamond Tile Drill Bit Kit – 5/8-11 Shank

Upgrade your tile and stone drilling with this 15-piece diamond tile hole saw kit from CenfeiTooL. Designed for precision and durability, this set includes eight core drill bit sizes (6mm, 8mm, 20mm, 25mm, 35mm, 50mm, 75mm, and 100mm), plus a 50mm chamfer saw, a 20mm finger milling bit, two 115mm cutting blades, and both SDS and hex shank adapters. Each bit features a 15mm thick vacuum-brazed diamond layer for superior wear resistance, faster cuts, and extended tool life compared to electroplated alternatives.

This kit supports both wet and dry drilling, with wide chip removal slots to prevent clogging and reduce dust. Compatible with angle grinders (5/8-11 thread), handheld drills, and bench drills—via included adapters—it delivers high-speed performance (recommended 6,000 RPM for bits under 4”, 3,000 RPM for 4” bits). Ideal for ceramic, porcelain, granite, marble, brick, and masonry, it handles drilling, chamfering, milling, and cutting in one versatile set.
