Diablo Hammer Drill Bit DMAPL4270 27/32 Inch SDS Plus 10 Inch (Rebar Demon 4-Cutter Full Carbide Head Reinforced Concrete Drilling)

Diablo DMAPL4270 27/32-Inch x 10-Inch SDS-Plus Rebar Demon 4-Cutter Hammer Drill Bit

The Diablo DMAPL4270 27/32-Inch x 10-Inch SDS-Plus Rebar Demon Hammer Drill Bit is a heavy-duty rotary drill bit engineered to bore anchor holes directly through steel-reinforced concrete, solid pour, brick, and block. Constructed with a 4-cutter full Dura-Carbide head joined via Tri-Metal Fusion Welding, an 8-inch flute working length, and SDS-Plus shank compatibility, this tool withstands operational temperatures up to 1800°F without head separation. Designed for corded and cordless SDS-Plus rotary hammers, this impact-resistant drill bit delivers up to 7X longer service life, solving rebar binding, carbide shear failure, and thermal hole distortion during commercial masonry anchor installation.

Best Used For:

• Reinforced Concrete Anchor Drilling: Boring 27/32-inch diameter anchor holes through structural concrete slabs and embedded steel rebar mats.
• Structural Dowel & Tie-Bar Penetrations: Slicing through rebar obstacles up to 8 inches deep to insert structural steel dowel rods.
• Heavy Masonry Wall Fastening: Executing clean, precise holes across cinder block, brick, and precast concrete for heavy-duty structural anchors.

Key Performance & Safety Features

• Full Dura-Carbide 4-Cutter Head: Solid carbide head takes controlled bites of embedded rebar to shatter steel obstacles without bit binding.
• 1800°F Thermal Heat Resistance: Proprietary Dura-Carbide formulation withstands double the industry heat standard to preserve cutting edge integrity.
• Tri-Metal Fusion Welding Technology: Creates a bond up to 3X stronger than traditional brazing to prevent head shear under severe impact.
• Optimized High-Volume Flute Geometry: Accelerates concrete dust extraction from the bore hole to keep the cutter head cool and clear.
• Precision Centering Tip Assembly: Prevents bit walking on smooth concrete surfaces to guarantee true, code-compliant anchor placement.

• (1) Diablo DMAPL4270 27/32 in. x 10 in. SDS-Plus Rebar Demon 4-Cutter Drill Bit

Technical Specifications

Pro-Tip: Maintain steady, firm forward pressure when the bit contacts embedded steel rebar rather than leaning excessively on the rotary hammer, allowing the 4-cutter head to shear through the metal cleanly.
