Product never used, packaging damaged during transport.

Product unopened, repackaged in our warehouses, in perfect working order, warranty available. 【Exceptional Craftsmanship】Our diamond drill bits are made of industrial-grade carbon steel and diamond abrasive.

A nickel coating protects them from corrosion.

They are meticulously crafted, extremely wear-resistant, and remarkably sharp. 【High-Quality Drill Bits】Each drill bit boasts a smooth and precise surface finish.

The thick diamond layer provides excellent cutting power for optimal drilling. 【Large Openings】These openings, positioned along the drill bit, facilitate the evacuation of chips and other particles during cooling and drilling.

This simplifies the drilling process. 【Versatility】This glass drill bit set includes 15 different drill bits to meet all your needs. It allows you to drill most hard surfaces, such as glass and tile. 【Caution】When cutting hard materials, always keep the tool at a low temperature to avoid damaging the material being drilled and premature wear of the tool; water lubrication is necessary during drilling, which can extend the life of the drill bit set.
