Diablo DMARG1070 1/4" x 4" x 6" SPEEDemon™ Red Granite PLUS™ Carbide-Tipped Hammer Drill Bit
MPN: DMARG1070
Minimum order quantity is .
Take on challenging concrete projects with the Diablo DMARG1070 SPEEDemon Red Granite PLUS Carbide-Tipped Hammer Drill Bit. Built for speed, endurance, and precision, this bit is optimized to drill fast and accurately through concrete, masonry, and stone while standing up to heat and heavy use.
- Carbide-tipped for heat resistance and longevity. The impact‑resistant carbide tip is brazed and hardened to withstand high temperatures, so you can push faster drilling without sacrificing tip life.
- Red Granite PLUS technology. Diablo’s advanced construction delivers up to four times longer bit life compared with standard bits, giving you fewer bit changes on demanding jobs.
- Grip Point Tip PLUS design. Multi-ground geometry creates an aggressive starting bite and clean, precise holes even in hard substrates, reducing wandering and« jamming.
- Impact Strong shank stability. Engineered to maintain shank integrity under heavy impact, maximizing performance with both cordless and corded impact drivers and rotary hammers.
- 1/4" diameter x 4" cutting length x 6" overall length. Ideal for pockets, anchors, and through-holes in concrete, masonry, and stone where size and control matter.
Where this bit excels
- Drilling fast, clean holes for anchors in poured concrete, brick and block, and stone surfaces.
- Creating pilot holes for hardware installation in retrofit projects, electrical or plumbing runs in masonry walls.
- Working in granite or other dense substrates where traditional bits heat up quickly and slow you down.
Who should consider the DMARG1070
- Professionals and tradespeople who demand durable performance from hammer drills and rotary hammers.
- Construction crews facing repetitive drilling tasks in hard materials where bit life and speed matter most.
- DIY enthusiasts tackling weekend projects that involve concrete, masonry, or stone work and want reliable results with fewer tool changes.
Why this bit is a practical choice
The combination of a carbide-tipped tip, optimized brazing and hardening, and the Grip Point Tip PLUS design translates to faster starts, reduced bit wandering, and longer service life. In real-world use, you’ll notice quicker hole creation in dense materials, smoother drilling with less heat buildup, and fewer interruptions to swap bits on long, tough jobs.
Practical tips for best results
- Use in hammer mode for concrete and masonry to maximize the bit’s aggressive bite.
- Keep the bit cool by withdrawing periodically to clear dust and reduce heat buildup during extended drilling sessions.
- Choose the correct drill speed and apply steady pressure—let the bit do the work and avoid forcing faster feeds that could overheat the tip.
