Diablo Rebar Demon SDS-Plus 7/8 Inch Full Carbide Head Hammer Drill Bit DMAPL4290 7X Life 18 Inch Length for Rebar and Deep Concrete Anchoring

Unstoppable Concrete Power: Diablo Rebar Demon Full Carbide Head SDS-Plus Bit for Maximum Depth and Durability in Reinforced Materials

Conquer the hardest jobs involving reinforced concrete and imbedded rebar with the single most durable solution on the market. Diablo’s revolutionary Rebar Demon™ SDS-Plus bits are the only bits designed with a 4-cutter full carbide head to withstand the stress and impact of cutting through hidden metal. This 7/8-inch diameter bit is essential for large-diameter anchor setting and deep concrete drilling applications with an 18-inch overall length.

These bits deliver up to 7X longer life versus standard 2-cutter hammer drill bits. Diablo’s proprietary Dura-Carbide™ features up to 2X more carbide that withstands up to 1800°F of intense heat—critical for combatting rebar hits. The Tri-Metal Fusion Welding ensures the full carbide head remains intact during extreme impact. With a Precision Tip for stability and an optimized flute design for faster dust removal, these bits ensure you deliver fast, precise holes even when pushing to a 16-inch working length.

Key Features

• 7X Longer Life: Provides up to 7X longer cutting life compared to standard 2-cutter hammer drill bits, maximizing productivity.
• Impact Resistant Full Carbide Head: 4-Cutter Full Carbide Head is built to withstand rebar impact and high-powered hammer drills for controlled, consistent wear.
• Extreme Heat Resistance: Features Diablo Dura-Carbide™ that resists temperatures up to 1800°F, critical when drilling reinforced concrete.
• Tri-Metal Fusion Welding: Up to 3X stronger weld keeps the full carbide head intact during extreme impact and prevents breakage.
• Deep Reach: 16-inch working length and 18-inch overall length are ideal for deep drilling, setting large anchors, and coring.
• Precision Tip: Delivers the stability and accuracy required for fast, precise holes for anchor setting.
• Optimized Flute Design: Removes dust faster, effectively keeping the carbide head cooler for ultimate strength and durability.
• Wear Mark Indicator: Ensures precise hole making by clearly indicating when the bit is worn and out of tolerance.
