Introducing the Diablo DMARG1120 3/8" x 4" x 6" SPEEDemon™ Red Granite PLUS™ Carbide-Tipped Hammer Drill Bit. Engineered for professional-grade performance, this bit redefines speed, durability, and precision when drilling into concrete, masonry, and stone.
What makes SPEEDemon Red Granite PLUS stand out
- Up to 4x longer bit life thanks to a unique brazing and hardening process that fortifies the carbide tip against heat and wear, so you can bore more holes before resharpening or replacement.
- Heat-resistant carbide tip designed to withstand the intense temperatures of high-speed hammer drilling, ensuring consistent, clean holes without tip dulling.
- Grip Point Tip PLUS design delivers aggressive starts and fast hole creation with less wandering, especially in tough materials where precision matters.
- Impact Strong technology enhances shank stability and durability, optimizing performance in both cordless and corded impact drivers and hammer drills.
Why this bit is ideal for pros and skilled DIYers
Whether you’re renovating a basement, installing anchors in new masonry, or crafting stone accents, the DMARG1120 is built to perform. The combination of SPEEDemon speed, Red Granite PLUS toughness, and a precision-grip tip translates to faster project completion with fewer passes and cleaner holes. It’s particularly effective in reinforced concrete, brick, block, natural stone, and thick masonry where other bits falter.
How it translates into real-world results
- Faster starts, fewer re-drills thanks to the multi-ground Grip Point Tip PLUS that reduces slip and improves hole quality from the first bite.
- Consistent performance across tools optimized for both cordless and corded impact drivers and hammer drills, so you don’t have to swap bits when you switch between tools on the jobsite.
- Reliable accuracy helps you align anchors, sockets, or inserts with precision, reducing the need for rework and saving material costs.
Designed for tough jobs and everyday use
Ideal for electricians, masons, remodelers, and serious DIY enthusiasts who demand dependable results in demanding materials. The DMARG1120 is compact enough for tight spaces yet powerful enough to handle heavy-duty drilling tasks, making it a versatile addition to any drill bit collection.
Specifications
Shank x Working Length x Overall Length: 3/8" x 4" x 6"
Application: Concrete, masonry, and stone drilling with hammer drills, optimized for high-speed, high-accuracy holes.
Practical tips for best results
- Use a drilling speed appropriate for the material—let the bit do the work and avoid forcing it through too quickly.
- Maintain steady pressure and use a slow-to-medium feed rate to preserve tip integrity and achieve cleaner holes.
- Pair with a sharp pilot hole in very dense materials to improve initial bite and reduce bit wandering.
- When drilling deep anchors, periodically withdraw the bit to clear debris and maintain drilling efficiency.
