Diablo Hammer Drill Bit Set DMAPL9920-S7 7 Piece (SDS Plus Rebar Demon 4 Cutter Full Carbide Head Reinforced Concrete Anchors)

Diablo DMAPL9920-S7 7-Piece SDS-Plus Rebar Demon 4-Cutter Full Carbide Head Hammer Drill Bit Set

The Diablo DMAPL9920-S7 7-Piece SDS-Plus Rebar Demon Hammer Drill Bit Set is a professional masonry drilling kit engineered to bore anchor holes through rebar-reinforced concrete, hard aggregate, and structural block. Ranging in diameter from 3/16 inch to 1/2 inch with working lengths up to 6 inches, these bits feature solid 4-cutter Dura-Carbide heads joined by Tri-Metal Diffusion Bonding to withstand thermal temperatures up to 1,800°F. Compatible with corded and cordless SDS-Plus rotary hammers, this rebar-cutting set solves head shear, rebar binding, and thermal fatigue during high-repetition concrete anchor setting operations.

Best Used For:

• Reinforced Concrete Anchor Setting: Drilling 3/16-inch to 1/2-inch anchor holes directly through embedded steel rebar mesh and high-PSI concrete.
• Commercial Electrical & Mechanical Fastening: Boring pilot holes for concrete screws, drop-in anchors, and threaded rod suspensions.
• High-Impact Rotary Hammer Drilling: Operating continuously in heavy SDS-Plus rotary hammers without carbide head detachment or thermal degradation.

Key Performance & Safety Features

• 4-Cutter Full Carbide Head Architecture: Solid carbide head geometry withstands heavy impact and prevents binding when striking embedded steel rebar.
• Extreme 1,800°F Heat Resistance: Proprietary Dura-Carbide matrix retains cutting edge hardness under intense friction generated during continuous rebar hits.
• Tri-Metal Diffusion Bonding Technology: High-strength brazing process creates a joint up to 3X stronger to keep the carbide head intact under severe shock loading.
• Optimized High-Volume Dust Flutes: Fast-evacuating flute geometry channels concrete dust away rapidly to reduce friction and keep the cutting head cool.
• Precision Centering Tip: Precision tip prevents bit walking during start-up, ensuring accurate hole placement for critical anchor specifications.

Technical Specifications

Pro-Tip: Allow the rotary hammer's weight to do the work when drilling through embedded rebar; applying excessive manual forward pressure can generate unnecessary thermal stress on the bit shank.
