DIABLO SDS PLUS 2 CUTTER DRILL BIT - 3/16" x 4"Rotary-hammer bit with a Dura-Carbide 2-cutter tip and four-flute body, sized for concrete, brick, and block. The 3/16" x 4" is the standard pilot for 1/4" Tapcon screws and most light-duty plastic anchors.
- Diameter: 3/16"
- Usable cutting length: 4"
- SDS-Plus shank fits all SDS-Plus rotary hammers
- Dura-Carbide tip withstands impact and high heat for longer life in concrete and masonry
- 2-cutter geometry centers fast for clean hole starts
- 4-flute body clears dust quickly to keep the tip cooler and reduce bit walk
Tip: For 1/4" Tapcons, drill the hole at least 1/4" deeper than the screw embedment so the cuttings have somewhere to collect.
