Gundlach 1/4" PTC Carbide Porcelain Drill Bit

The Tile Drill Bits are high-quality tools designed for accurate hole drilling in various materials, particularly tiles. They feature a diamond ground tip geometry that provides excellent bite and easy start-up. It's important to use them with pressurized water to keep them cool. The bits have a special carbide tip that ensures precise hole placement and minimizes drill bit wander. They are recommended to be operated at speeds between 700 and 900 Rpm. To maintain their sharpness and prevent overheating, it's advised to spray water on the PTB bit while drilling. Although primarily used for tiles, the PTB carbide drill bits can also be used in other materials like marble, granite, travertine, natural slate, quarry tiles, ceramic tiles, natural stone, limestone, and rosemary roof tiles. However, they are not suitable for wood and do not last as long as diamond hole saws. These drill bits are made in the UK from P100 grade carbide, ensuring durability and quality. Additionally, the PTB 1/4" carbide bit can be used to drill a pilot hole when using the PTB water feed adapter for Diamond Crowns.
