Steel drill bits, 10-pack, suitable for tile, glass, ceramic and marble, with 6 mm tungsten carbide drill bits.

[Alloy Steel]: This drill bit set is forged from high-quality alloy steel. These glass drill bits can be used for precise, clean drilling into ceramic tiles, marble, mirrors, glass, aluminum, concrete, and wood. For best results, it is recommended to thoroughly lubricate the drill bits. Typically, lubrication is achieved simply by rinsing the drill hole surface with water.[Size]: These multi-material drill bits feature a sharp 6mm tip and a 6.35mm (1/4 inch) diameter, reducing the risk of breakage.

Our drill bit shapes are as follows:These spears are sturdy and durable.[Applications]: Suitable for drilling ceramic tiles, glass, marble, and mirrors. Water lubrication is recommended when drilling hard materials. Proper cooling can extend the life of the drill bit. Glass drill bits are typically used in conjunction with an electric drill for drilling all of the above materials.[Tungsten Carbide Drill Bits]: These ceramic drill bits are made of tungsten carbide, improving drilling efficiency and extending service life. During drilling, the coating rubs against the glass, creating perfect holes. [Packaging Contents]: The package contains 10 6mm glass and ceramic tile drill bits and a convenient plastic storage box.
