Diablo SDS Plus Hammer Drill Bit DMAPL4000 5/32 x 4 Inch Rebar Demon (4 Cutter Full Carbide Head Dura Carbide 1800F Concrete Anchor Setting)

Diablo DMAPL4000 5/32-Inch x 4-Inch SDS-Plus Rebar Demon 4-Cutter Full Carbide Drill Bit

The Diablo DMAPL4000 Rebar Demon is a 5/32-inch diameter SDS-Plus rotary hammer drill bit engineered with a 2-inch working length and a 4-inch overall length for drilling anchor holes into reinforced concrete. Featuring a 4-cutter solid carbide head manufactured with Dura-Carbide technology to withstand operating temperatures up to 1800°F, this high-durability masonry bit penetrates steel rebar without binding or head breakage. Built using a Tri-Metal Fusion Welding process that provides 3X stronger weld adhesion than traditional brazing, it delivers up to 7X extended service life compared to standard 2-cutter bits while using a 90-degree pyramid centering tip and progressive flute geometry for precise anchor placement.

Best Used For:

• Reinforced Concrete Mechanical Anchor Installation: Drilling precise 5/32-inch pilot holes into steel-reinforced foundation slabs and precast panels for small expansion anchors.
• Masonry & Cinder Block Fastening: Penetrating dense poured concrete, structural brick, and cinder block for electrical conduit straps and junction box mounting.
• Overhead Structural Ceiling Anchoring: Drilling clean overhead concrete holes with minimal vibration to set drop-in anchors and mechanical fasteners safely.

Key Performance & Safety Features

• 4-Cutter Solid Carbide Head: Solid carbide tip geometry distributes wear evenly and prevents bit lockup when impacting embedded steel rebar.
• 1800°F Dura-Carbide Formulation: Specialized high-density carbide alloy maintains structural hardness under extreme friction heat generated during rebar strikes.
• Tri-Metal Fusion Welding Process: Industrial bonding technology joins the full carbide head to the steel shank with triple the joint strength of standard brazing.
• Precision 90-Degree Pyramid Centering Tip: Sharp center spur establishes immediate point tracking to eliminate bit walking on smooth concrete surfaces.
• Progressive Fast-Evacuation Flutes: Optimized flute geometry clears abrasive concrete dust rapidly to keep the carbide cutter cool and preserve hole tolerance.
• Integrated Wear Mark Indicator: Visual indicator line shows exact carbide head wear to ensure drilled holes meet ANSI anchor sizing specs.

Technical Specifications

Pro-Tip: Allow the rotary hammer's impact mechanism to do the work when encountering rebar; applying heavy manual forcing pressure generates excessive heat that reduces carbide tooth life.
