## Description

This 2-in-1 drill bit set combines precision drilling with edge trimming capabilities for a range of materials commonly encountered in home improvement and craft projects. It is designed to tackle tile, glass, marble, ceramics, granite, and related surfaces, making holes in sizes 3/16 in. 1/4 in. 5/16 in. 3/8 in. and 1/2 in. while also producing clean edge finishes along cuts. The hex shank is compatible with standard drills, typically a 3/8 in. or 1/4 in. chuck, which supports straightforward bit changes and broad compatibility with common drill models. A cooling wax lubrication system is included to reduce friction and heat during use; the wax application minimizes heat-related stress on delicate materials and helps maintain surface integrity without the need for water cooling. The bits utilize a vacuum brazed diamond coating, which is thickened to resist grit loss and wobble during heavy use, delivering stable cuts with consistent penetration across hard materials. The coating also provides corrosion resistance, contributing to long term durability in challenging tile and stone tasks. A transparent storage case keeps the set organized and readily accessible in a workshop or on a job site. In short, the configuration is suited for both professional tasks and home projects that involve tile and stone work, glass art, and fixture installations.
