Professional SDS-Plus 5/16 Inch Pilot Centering Bit for Thin Wall Carbide Core Drilling

The Diablo DMAPLCC1920 is an industrial-grade 5/16-inch diameter by 6-inch long SDS-Plus pilot bit engineered to serve as the precise centering guide for thin-wall carbide-tipped core bits in heavy masonry applications. Forged from high-alloy structural steel and optimized via a proprietary high-temperature brazing and hardening treatment, this anchoring accessory maintains absolute stability under continuous high-impact loads. Designed to prevent walking and guide deep core cutters, it satisfies strict building code layout specifications across cured concrete, brick, block, and stone substrates when driven by corded or cordless rotary hammers.

Best Used For:

  • HVAC Duct Routing Center Holes: Guiding thin-wall core bits straight through exterior masonry blocks to pass refrigerant lines and structural drain piping.
  • Electrical Conduit Penetration: Locating and centering deep large-diameter bores in commercial concrete walls for smooth service panel conduit feeds.
  • Commercial Plumbing Line Coring: Maintaining perfect axial alignment during deep multi-inch coring setups with the aid of a 4-inch structural tool extension.

Key Performance & Safety Features

  • Anti-Walking Grip Point: Precision-ground 5/16-inch centering tip establishes immediate mechanical traction to ensure perfectly axial hole starts.
  • Advanced Thermal Brazing: Industrial heat-treatment hardening process significantly reinforces core strength against fracture under high operational friction thresholds.
  • Extension Mandrel Integration: Machined shank slides smoothly into standard 4-inch SDS-Plus extension adapters for deep structural slab boring paths.
  • SDS-Plus Keyed Chuck System: Direct snap-in drive geometry ensures efficient kinetic impact transfer from the internal pneumatic piston mechanism.
  • Cordless Battery Efficiency: Optimized mass profile reduces parasitic mechanical resistance to extend runtime limits per single cordless tool charge.

What's Included

  • (1) Diablo 5/16" x 6" Pilot Bit for SDS-Plus Core Bits (DMAPLCC1920)

Pro-Tip: When using this pilot bit within a large thin-wall masonry core bit assembly, disengage the pilot bit screw set and remove the guide bit as soon as the core body cuts a stable, 1/4-inch deep circular tracking groove into the concrete. Removing the pilot bit after centering eliminates internal tool friction and accelerates core extraction speeds considerably.
