4-in-1 Brazed Diamond Chamfering Bit, M10 Universal Grinder Step Drill Bit, 2pcs Mix for Tile Stone Marble Edge Finishing

This 4-in-1 brazed diamond chamfering bit is professionally designed for angle grinder polishing and drilling work, perfectly compatible with tile, ceramic, marble, granite and glass materials. Adopting high-density brazed diamond particles, it delivers sharp and stable cutting and grinding performance, effectively finishing smooth hole trimming and clean edge shaping without rough burrs. Made of premium wear-resistant alloy material, the drill bit withstands high-speed operation and frequent repeated use, featuring a conical structure that accelerates debris discharge, effectively preventing clogging and overheating during construction. Equipped with standard M10 thread and matching adapter rod, it boasts universal compatibility with most angle grinders. Available in 10-38mm and 10-50mm specifications, it meets diverse hole expanding and edge finishing needs for home renovation, countertop production and workshop engineering projects.

• Premium Brazed Diamond & Durable Alloy Build Featured with high-density uniformly brazed diamond particles, this diamond chamfering bit ensures outstanding cutting and grinding sharpness and abrasion resistance. The high-strength wear-resistant metal alloy body supports long-term high-speed grinding operation, not easy to deform or wear, greatly extending the overall service life and meeting frequent construction use demands.
• Efficient Anti-clog & Heat Dissipation Design Adopts optimized conical streamlined shape, which can quickly discharge stone dust and debris generated during drilling and chamfering processes. It effectively avoids tool clogging, grinding stagnation and excessive heat accumulation, ensures continuous and smooth operation, and improves construction efficiency while reducing tool loss caused by high temperature.
• Universal M10 Compatibility & Easy Installation Comes with standard M10 threaded shank and supporting adapter rod, realizing universal fit for most mainstream angle grinders on the market. No complicated installation steps are required, it can be quickly assembled and disassembled, adapting to various usage scenarios such as home improvement, garage processing and on-site engineering construction with strong flexibility.
• 4-in-1 Multifunctional Integration Integrates four core functions of hole enlarging, edge chamfering, bevel polishing and irregular edge shaping in one tool. It replaces multiple single-function drill bits, saves tool storage space and tool replacement time, greatly improves working efficiency, and is ideal for tile laying, stone countertop finishing and various stone processing projects.
• Wide Application & Adjustable Working Diameter Available with two common working diameter ranges of 10-38mm and 10-50mm, covering most daily and engineering hole trimming and edge finishing tasks. It works perfectly on porcelain, ceramic, marble, granite, glass and other hard materials. Water cooling operation is recommended for hard stone processing to further stabilize working effect and prolong tool life.
