Description

Master the Hardest Masonry Surfaces with Diablo’s 5-Pack Carbide-Tipped Red Granite Hammer Bits

The Diablo DMARG1070-P5 Red Granite Hammer Drill Bit 5-Pack is the professional’s answer for high-speed, precision drilling in red granite, marble, and natural stone. Engineered with a specialized Grip Point Tip PLUS™ design, these bits provide aggressive, non-slip starts that are essential for maintaining accuracy on polished or uneven surfaces. Whether you are anchoring hardware into a granite facade or performing intricate masonry repairs, these 1/4-inch bits deliver up to 4X longer life than standard bits, allowing you to breeze through dense materials that would quickly dull ordinary masonry fasteners.

Forged for the high-intensity demands of the modern jobsite, these bits are Impact Strong™ and optimized for both high-torque impact drivers and hammer drills. A high-performance brazing and hardening process ensures the carbide tip withstands extreme heat and impact, while the optimized "U-Flute" design rapidly evacuates dust to keep the bit cool and maintain drilling speed. Featuring a universal 1/4-inch hex shank that eliminates spinning in the chuck, the DMARG1070 series maximizes power transfer from your tool to the material, providing more holes per battery charge in cordless applications.

Key Features

  • Extreme Heat Resistance: Specialized carbide tip is brazed and hardened to withstand high-impact drilling in red granite and dense stone.
  • Grip Point Tip PLUS™: Delivers superior stability and non-slip starts for the precision required in professional stone work.
  • Optimized U-Flute Design: Removes dust faster than standard flutes, keeping the carbide tip cooler for ultimate durability.
  • Impact Strong™ Hex Shank: Increases shank stability and prevents bit slippage in both impact drivers and hammer drills.
  • Cordless Efficiency: Engineered to provide more holes per charge in cordless hammer and rotary drilling applications.

Pro-Tip: To extend the life of your carbide tip when drilling into dense red granite or marble, use a steady "in-and-out" motion. This helps the U-flute evacuate dust more effectively, which prevents heat buildup—the number one cause of carbide failure. Letting the bit "breathe" while maintaining high RPM will ensure faster cuts and more holes per bit.
