Meet the Diablo DMAPL4150 3/8" x 6" x 8" Rebar Demon™ SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bit. Built for reinforced concrete and rebar work, it’s the kind of bit that pros reach for when uptime matters and precision matters more. If you want faster, cooler drilling with a bit that actually lasts, this one checks the boxes.

Key Features & Design

• 4-Cutter Full Carbide Head – Impact resistant design that extracts smaller bites of rebar for controlled carbide wear and reduced vibration to deliver fast, precise holes.
• Diablo’s Dura-Carbide™ – Features up to 2X more carbide that withstands up to 1800°F of intense heat to combat rebar hits versus standard bits that fail at 800°F.
• Tri-Metal Fusion Welding – Features up to 3X stronger weld to keep the full carbide head intact during extreme impact such as rebar.
• Precision Tip – Delivers stability and accuracy required for fast, precise holes.
• Application – Application: Reinforced concrete and concrete
• Ideal For – Ideal For: Up to 7X longer life versus standard 2-cutter hammer drill bits
• Specifications – 3/8" diameter x 6" length (cutting) / 8" overall length and SDS-Plus compatibility for use with standard hammer drills.

Designed to tackle the tough job sites without breaking a sweat, the Rebar Demon bit minimizes rebar damage, reduces vibration, and keeps going long after lesser bits have called it a day. It’s the kind of reliability that makes you wonder how you ever drilled without it—until you forget your punch card and realize it’s paid for itself in fewer, cleaner anchoring jobs.
