Meet the Diablo DMAST1010 3/8" x 1-1/16" SDS-Plus 2-Cutter Carbide-Tipped Hammer Stop Bit — a precision-focused drilling solution designed for fast, accurate concrete holes with a built-in depth stop for shallow anchor installations. Built to maximize speed and longevity, this bit is crafted to keep you productive from first bore to final set.

• Depth-controlled performance: The integrated Stop Collar provides a pre-set stopping point, eliminating over- or under-drilling and ensuring consistent anchor depth every time.
• 2-Cutter carbide-tipped design: The dual-cut geometry works in tandem with hardened carbide tips, delivering quicker material removal and extended bit life through a refined brazing and hardening process.
• Optimized for SDS-Plus, corded or cordless: Engineered to extract maximum performance from both wired and battery-powered rotary hammers, maintaining steady drilling in concrete environments.
• Compact, precise dimensions: 3/8" diameter with a 1-1/16" reach, ideal for shallow anchor work where clean holes and exact depth matter most.
• Durable, field-ready construction: Built to withstand repeated hammering and harsh concrete conditions, delivering reliable repeatability across jobs.

Ideal for professionals and serious DIYers tackling concrete anchor installations, this bit shines in scenarios such as mounting electrical panels, securing fixtures to concrete walls or floors, and any task where precise depth control saves time and materials. The depth-stop feature reduces guesswork across multiple holes, helping you maintain uniform anchor depths on every installation run.

1. Attach the DMAST1010 to your SDS-Plus hammer drill compatible with 3/8" bits.
2. Set the depth stop collar to your target anchor depth.
3. Begin drilling with steady pressure and the hammer’s percussive action to engage the carbide tips.
4. Withdraw occasionally to clear debris, then proceed to install anchors at the pre-determined depths.

Choose the Diablo DMAST1010 when you need speed, reliability, and controlled depth in concrete drilling. Its advanced carbide tips, dedicated depth stop, and SDS-Plus optimization deliver repeatable, professional results that help you finish projects faster with less rework.
