Meet the Diablo DMARG1100 5/16" x 4" x 6" SPEEDemon Red Granite PLUS Carbide-Tipped Hammer Drill Bit — built for professionals who demand speed, precision, and long life when drilling into concrete, masonry, and stone. This bit is engineered to excavate fast while maintaining hole accuracy, even under heavy torque from modern hammer drills and impact drivers.
What sets it apart is a combination of advanced carbide technology and a purpose-built manufacturing process. The carbide-tipped tip is hardened and brazed with a heat-resistant bond, so it stands up to high temperatures without dulling. That means fewer bit changes on tough jobs and cleaner, more accurate holes from start to finish.
- SPEEDemon™ technology delivers faster drilling in concrete, masonry, and stone, helping you move from pilot hole to finished hole in less time.
- Red Granite PLUS™ design paired with an optimized brazing/hardening process provides exceptional durability and long life — up to 4x longer than conventional carbide bits in demanding applications.
- Grip Point Tip PLUS™ offers an aggressive start for clean, true holes with less wandering, even when you’re drilling from awkward angles or through dense materials.
- Impact Strong™ architecture increases shank stability and reduces wobble in both cordless and corded impact/drill drivers, improving control and reducing bit heat during extended use.
- Size specification: Diameter 5/16", flute length 4", overall length 6" for versatile drilling in a range of concrete and masonry applications.
Ideal for trade professionals and serious DIYers tackling anchor holes, conduit passes, and fastener installation in poured concrete, AAC blocks, brick, stone, and concrete-led masonry. Whether you’re wiring a new workshop, mounting cabinets, or setting anchors for heavy equipment, this bit provides dependable performance when you need holes that start quickly and stay straight.
How this bit compares to standard options: the carbide-tipped tip stays sharper longer under heat, the Grip Point design reduces wandering on initial contact, and the Impact Strong shank geometry minimizes tool bit fatigue in high-torque drivers. The result is fewer interruptions for bit changes, more consistent hole quality, and a smoother drilling experience overall.
Practical tips for best results: use a hammer drill or impact driver with a steady feed rate, start with a light touch to let the Grip Point start cleanly, and avoid excessive pressure that can generate heat. For long jobs, pause to cool the bit and use adequate lubrication if the material calls for it. With the DMARG1100, you’ll gain reliable performance from first hole to last, even in demanding concrete and stone projects.
