Diablo DMAST1050 5/8" x 2-1/16" SDS-Plus 2-Cutter Carbide-Tipped Stop Bit
MPN: DMAST1050
Minimum order quantity is .
Meet the Diablo DMAST1050, a purpose-built SDS-Plus stop bit engineered for fast, precise concrete drilling with a built-in depth stop. At 5/8" (0.625") in diameter and 2-1/16" (about 52 mm) long, this bit is designed to deliver consistent depth and clean holes for shallow anchor installations—even in demanding job sites.
- Stop Collar for consistent depth: The integrated depth-stop ensures you hit the exact anchor depth every time, reducing rework and protecting embedded hardware.
- 2-Cutter carbide-tipped design: Twin cutting edges bite quickly into concrete, reducing dwell time and minimizing wandering for straighter, more accurate holes.
- Carbide-tipped longevity: The hard carbide tips resist wear, delivering more holes per bit and extended life in tough mortar and dense concrete.
- Optimized brazing and hardening: A refined bonding and heat-treatment process increases tip retention, enhances impact resistance, and sustains productivity across a full drilling shift.
- SD S-Plus compatibility: Specifically engineered for both corded and cordless SDS-Plus rotary hammers, delivering dependable performance across typical contractor tool kits.
Why this matters on real jobs: installing anchors for electrical, plumbing, or mechanical fixtures often requires precise depth control and fast drilling through concrete. The DMAST1050 eliminates guesswork—set your depth stop, drill in clean, controlled bursts, and pull out to clear dust. The result is repeatable depth accuracy, fewer holes that need to be redrilled, and a cleaner installation overall.
Use cases & scenarios:
- Secure electrical boxes, conduit brackets, or mechanical supports into concrete walls and floors with consistent embedment depth.
- Anchor installations in concrete slabs where depth accuracy prevents protruding hardware and ensures flush surfaces.
- Dense or reinforced concrete environments benefit from the carbide-tipped edge's wear resistance and long service life.
Tips for best results: operate with a steady, moderate speed and let the bit do the work. Use short drilling bursts to manage heat, pause to clear cuttings, and verify the depth stop setting after every few holes. Keep the bit perpendicular to the surface for clean, true holes, and pair with compatible SDS-Plus hammers for top performance.
The Diablo DMAST1050 5/8" x 2-1/16" SDS-Plus 2-Cutter Carbide-Tipped Stop Bit is the reliable choice for professionals who demand precision, durability, and depth control on concrete installations.
