Diablo 1/8 Inch x 3 Inch Red Granite Carbide-Tip Hammer Drill Bit Impact Rated Self-Feeding Masonry Boring Bit with 1/4 Inch Hex Shank DMARG1010

Drill Through the Hardest Stone with Ease Using Diablo’s Carbide-Tipped Red Granite Hammer Bits

The Diablo DMARG1010 Red Granite Hammer Drill Bit is the ultimate professional solution for high-speed drilling in the toughest masonry materials. Engineered with a specialized Grip Point Tip PLUS™ design, this bit provides the aggressive starts and surgical precision needed for fast, clean holes in red granite, marble, and natural stone. Whether you are installing hardware in residential masonry or performing commercial stone fabrication, this 1/8-inch bit delivers up to 4X longer life than standard masonry bits, ensuring your project stays on track even when facing the densest materials.

Built for the modern jobsite, this bit is Impact Strong™ and fully rated for use in both high-torque impact drivers and standard hammer drills. The high-performance brazing and hardening process allows the carbide tip to withstand extreme heat and impact, while the optimized "U-Flute" design evacuates dust rapidly to keep the bit cool and maintain drilling speed. With a universal 1/4-inch hex shank that prevents spinning in the chuck, you get maximum stability and power transfer, making this bit a high-efficiency essential for any contractor working with concrete, brick, or block.

Key Features

Specifications

Pro-Tip: When drilling into hard natural stone like granite or marble, start at a low RPM to allow the Grip Point Tip to seat itself. Once the hole is started, increase to high speed with steady pressure, occasionally backing the bit out while it’s spinning to help clear dust from the flute. This prevents heat buildup and preserves the sharpness of the carbide tip for multiple holes.
