Diablo 1/4 Inch x 6 Inch Red Granite Carbide-Tip Hammer Drill Bit 5-Pack Impact Rated Self-Feeding Masonry Boring Bits 1/4 Inch Hex Shank DMARG1070-P5

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.

Specifications

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.
