Diablo DMARG1190 3/4" x 4" x 6" SPEEDemon™ Red Granite PLUS™ Carbide-Tipped Hammer Drill Bit
MPN: DMARG1190
Minimum order quantity is .
Introducing the Diablo DMARG1190 SPEEDemon Red Granite PLUS Carbide-Tipped Hammer Drill Bit — a purpose-built solution for professionals who demand speed, precision, and lasting performance when drilling into concrete, masonry, and stone. With a 3/4" diameter and a 6" overall length (3/4" x 4" flute), this bit is engineered to deliver deep, clean holes with fewer passes and less wobble, even in demanding jobs.
What makes it stand out
- Carbide-tipped durability — optimized brazing and hardening create a heat-tolerant tip that stays sharp under heavy use, reducing dwell time and rework on tough materials.
- Grip Point Tip PLUS design — delivers aggressive starts for quick, accurate hole initiation and minimizes wandering in hard surfaces.
- Impact Strong shank — enhanced shank stability improves performance in both cordless and corded impact drivers and hammer drills, reducing bit wobble and chatter.
- Up to 4X longer life — engineered for endurance in concrete, masonry, and stone, meaning fewer bit changes on big projects and lower total cost per hole.
- Red Granite PLUS construction — a robust carbide solution specifically optimized for demanding masonry environments, delivering fast drilling with reliable cooldown under load.
Ideal use cases
- Installing anchors, fasteners, or conduit in concrete slabs, foundations, and poured walls where precision and speed matter.
- Drilling through hard masonry blocks, brickwork, and natural stone surfaces without overheating the tip.
- Renovation and construction projects that require deep, straight holes with clean edges for a professional finish.
- Professional contractors and serious DIYers who tackle frequent masonry drilling and want a single-bit solution that lasts.
How this bit improves your workflow
When you’re on a job, time is money. The SPEEDemon Red Granite PLUS bit cuts faster and cleaner, meaning fewer passes and less effort to reach your depth. The heat-tolerant carbide tip maintains edge integrity, so you spend less time resharpening or changing bits. The Grip Point Tip PLUS begins cutting with confidence, reducing wandering in dense materials, while the Impact Strong shank keeps the bit centered and stable under continuous hammering.
Guidelines for best results
Use in a compatible hammer drill or impact hammer with the appropriate drilling mode. Start at a steady speed to establish a clean bite, then increase as needed while applying even, controlled pressure. Let the bit do the work—avoid forcing it through the material, especially at deeper depths. For extended use in dense materials, periodically pause to inspect the tip and allow for cooling to preserve edge life.
