Diablo 3/8 Inch x 6 Inch Red Granite Carbide-Tip Hammer Drill Bit Impact Rated Self-Feeding Masonry Boring Bit with 1/4 Inch Hex Shank DMARG1120

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

The Diablo DMARG1120 Red Granite Hammer Drill Bit is the professional’s answer to drilling through red granite, marble, and natural stone with surgical precision. Engineered with a specialized Grip Point Tip PLUS™ design, this bit provides aggressive, non-slip starts that are essential for maintaining accuracy on polished or uneven stone surfaces. Whether you are anchoring hardware into a granite facade or performing intricate masonry repairs, this 3/8-inch bit delivers 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, this bit is 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 DMARG1120 maximizes power transfer from your tool to the material, providing more holes per battery charge in cordless applications.

Key Features

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.
