Glass Tile Drill Bit Set - 7pcs Carbide Drill Tools

7-piece professional glass and tile drill bit set for use on glass, ceramics, porcelain, marble, travertine, stone, concrete, brick, cement, and hard plastic. Carbide with excellent wear resistance. Double U-groove shank and 3-sided shank design for stable fixation and reduced dust. Ideal for power drills, hand drills, and bench drills — always with water cooling for safe, splinter-free drilling.

·Precision: Ensures crack-free, splinter-free drill holes in delicate materials such as glass and tiles — no chipping or edge damage thanks to carbide drill tips and stepped drilling (3 mm to 12 mm). Ideal for renovation projects where precision is essential.

·

·Wear Resistance: Hard metal offers extended service life during repeated drilling in hard surfaces such as concrete, stone, and porcelain — lasting up to 3× longer compared to standard drill tips, without replacement during major jobs.

·

·Secure Fixation: 3-Flat shank + double U-groove provide distinction against slipping in power drills, hand drills, and bench drills — prevents unintended movement and improves control during water-cooled drilling.

·

·Stress-Free Maintenance: Includes hassle-free return and exchange service via email support — no hassle with any size or functionality questions, so you can focus on the result, not the logistics.
