3/16" rotary masonry drill bit for clean, fast drilling in brick, cinder block, concrete block, and ceramic tile. The carbide tip cuts the masonry and the fast-spiral double flute clears chips quickly so the bit doesn't bind or overheat in deep holes.

• Carbide-tipped head for long life in hard masonry
• Fast-spiral double flute for rapid chip removal
• For brick, cinder block, concrete block, and ceramic tile
• Round shank - use in a corded or cordless rotary drill only
• NOT for hammer drilling and NOT for SDS or SDS-Plus rotary hammers
• Bit size: 3/16" diameter x 4" overall length

Tip: 3/16" is the standard pilot size for 1/4" Tapcon-style concrete screws. Run the drill at a moderate speed with steady pressure and back the bit out every inch or so to clear dust from the flutes.
