Bosch PTBX38 3/8" x 5" Porcelain Tile Drill Bit (4-Pack)

The Bosch PTBX38 3/8" x 5" Porcelain Tile Drill Bit is designed for drilling into hard materials like porcelain, ceramic, marble, and granite tiles. Its durable carbide tip is optimized for ceramic tile drilling, offering up to five times more life compared to Bosch glass and tile bits when used on porcelain tile. The innovative arrow-shaped head design facilitates faster drilling with less friction, reducing wear and tear on the bit. It also features an enhanced centering zone for easier and more precise positioning. The impact-rated hex shank ensures maximum torque transmission and a secure connection with the chuck, making it compatible with ¼ In. hex impact drill/drivers and 3-jaw chuck drill/drivers.
