Unyielding Power in Stone: Diablo SPEEDemon™ Red Granite PLUS™ Carbide Hammer Drill Bit

The Diablo DMARG1070 SPEEDemon™ Red Granite PLUS™ Hammer Drill Bit is the professional's answer to the most demanding masonry and stone drilling tasks. Engineered with a unique brazing and hardening process, this impact-resistant carbide-tipped bit is designed to withstand extreme heat and high-impact forces that typically dull standard masonry bits. Whether you are drilling into reinforced concrete, hard granite, marble, or decorative stone, this bit provides an aggressive and accurate solution that outlasts standard masonry bits by up to 4X, ensuring maximum jobsite productivity.

Precision and stability are at the forefront of the DMARG1070 design. Featuring the specialized Grip Point Tip PLUS™, this bit enables aggressive starts with pinpoint accuracy, preventing bit walking and ensuring clean, fast holes every time. The optimized "U-Flute" geometry rapidly evacuates dust to keep the carbide tip cooler, while the Impact Strong™ hex shank provides a universal fit that eliminates spinning in the chuck. Optimized for cordless tools, this bit delivers more holes per battery charge, making it an essential addition for contractors who need reliable performance in both corded and cordless impact drivers and hammer drills.

Key Features

  • 4X Longer Life: Proprietary carbide tip withstands high heat and impact for four times the durability of standard bits.
  • Grip Point Tip PLUS™: Multi-ground tip design delivers the stability and accuracy required for aggressive, precise starts.
  • Optimized U-Flute: Removes dust faster to keep the bit cooler, preserving the integrity of the carbide tip.
  • Impact Strong™ Shank: Engineered to maximize shank stability and durability in high-torque impact and drill drivers.
  • Anti-Slip Hex Shank: Provides universal fitment and eliminates bit spinning in the chuck for ultimate impact resistance.
  • Cordless Efficiency: Advanced design is optimized to provide more holes per charge in cordless rotary and hammer drilling.
  • Multi-Material Versatility: Ideal for drilling into concrete, brick, block, stone, marble, and granite.

Pro-Tip: When drilling into hard stone like granite or marble, start at a low RPM to let the Grip Point Tip PLUS™ establish a firm seat in the material. Once the hole is started, maintain moderate pressure and let the "U-flute" effectively clear the dust; pulling the bit slightly back every few seconds will help evacuate debris faster and keep the carbide head at its optimal operating temperature.
