Specifications

Pro-Tip: When using a carbide-tipped pilot bit on brittle materials like tile or stone, start your drill at a low speed and avoid using the hammer function. Let the sharp carbide tip scour the surface to create a starting divot before increasing speed, preventing the bit from skating across the smooth surface.
