1. 17-Piece Diamond Tool Kit: Includes 11 diamond core drill bits (1/4" x2, 5/16", 3/8", 1/2", 3/4", 1", 1-3/8", 2", 3", 4"), two 4-1/2" diamond cutting blades, one 3/4" grinding bit, one 1-3/8" chamfer bit, one 5/8"-11 to 3/8" hex shank adapter, and cooling wax.

2. Vacuum Brazed Diamond Technology: Diamond grit is vacuum brazed onto a steel body at high temperature, creating a strong and uniform bond that supports steady cutting performance and consistent results across repeated use.

3. Triangular Slot with Core Eject Design: Triangular slots on the bit body help remove chips and dust during drilling, while the multi-hole layout allows the drilled core slug to be pushed out easily, reducing clogging and supporting smoother operation.

4. Wide Material and Task Versatility: Designed for drilling, cutting, chamfering, and grinding porcelain tile, ceramic, granite, marble, and natural stone, suitable for countertop faucet and tile installation work.

5. Tool Compatibility and Usage Notes: Directly compatible with 115mm angle grinders via the 5/8"-11 thread, and can be used with electric drills using the included 5/8"-11 to 3/8" hex shank adapter. Use water or cooling wax during operation and wear proper eye and hand protection.
