Unique Design - The HSS tile drill bit features a double-threaded U-groove design, which is smooth and flat, and effectively eliminates chips. The 3-angle handle adjustment makes the drill bit more stable on the electric drill, preventing slippage.

Performance - The glass drill bit is made of strong alloy, resulting in low cutting resistance. The surface of the tile drill bit is fully ground and rust-proof, with high hardness.

Wide Application - The tile drill bit can be installed on hand drills, drill presses, and electric drills.

Ceramic tile drill bits can be used to drill glass bricks, tiles, plastics, wood, thin metal, jade, shells, etc.

Please Note - When drilling with the ceramic tile drill bit, proceed from slow to fast, and do not apply excessive pressure. When drilling hard materials, add water to cool the drill bit. If the drill bit is used for an extended period, the temperature may become too high and damage it.
