Diablo 5/8" x 2-1/16" SDS-Plus 2-Cutter Carbide-Tipped Stop Bit is engineered for fast, accurate drilling in concrete and brick/block applications, making it a go-to choice for professionals setting shallow anchors. Diablo's carbide-tipped design - combined with a precision Stop Collar - gives users a reliable, predetermined stopping depth so every anchor installation is consistent and efficient. Optimized for both corded and cordless SDS-Plus rotary hammer drills, this bit delivers one of the fastest and longest lasting drilling solutions available for masonry work.

Key Features

• Diablo-made carbide withstands impact and high heat applications - dramatically extending bit life compared to standard hammer drill bits, reducing replacement frequency on the job
• Stop Collar with a pre-determined stopping point - ensures consistent, accurate hole depth for efficient shallow anchor installations without measuring each time
• Optimized brazing and hardening process on carbide tips - increases tip longevity and maintains cutting performance through demanding concrete and masonry drilling tasks
• 2-cutter carbide tip design - delivers fast material removal and clean, accurate holes in concrete and brick/block surfaces
• Optimized for maximum performance in corded and cordless SDS-Plus rotary hammers - provides versatile compatibility across a wide range of jobsite tools
• 5/8" diameter with a 2-1/16" working length - sized for common anchor-setting applications in concrete and masonry

Why This Product

• The built-in Stop Collar eliminates guesswork during shallow anchor installations - the bit stops at the exact required depth every time, improving accuracy and saving time on repetitive fastening tasks in concrete and brick/block.
• Diablo's proprietary carbide brazing and hardening process means this bit lasts significantly longer than standard hammer bits, reducing downtime and tooling costs on demanding masonry drilling jobs.
• SDS-Plus shank compatibility makes this bit suitable for both corded and cordless rotary hammer drills, giving crews flexibility to use the tools already on hand without adapters or special equipment.
• Designed specifically for anchor setting in concrete and brick/block, this stop bit is a purpose-built solution that handles the most common shallow anchor installation scenarios quickly and accurately.

Frequently Asked Questions

What is the working length of the DMAST1050 stop bit?

The working length of this Diablo SDS-Plus stop bit is 2-1/16", which defines the usable cutting depth before the Stop Collar contacts the surface - ideal for shallow anchor installations in concrete and brick/block.

What does the Stop Collar do on this drill bit?

The Stop Collar provides a pre-determined stopping point so the bit drills to a consistent, accurate depth without additional measuring. This makes shallow anchor installations faster and more uniform across multiple holes.

Will this bit work with cordless rotary hammer drills?

Yes - this Diablo SDS-Plus stop bit is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammer drills, making it flexible for a variety of jobsite setups.

What materials can the DMAST1050 drill through?

This stop bit is designed to drill through concrete and brick/block. The carbide-tipped 2-cutter design handles the impact demands of masonry drilling while the Diablo brazing and hardening process extends tip life through tough applications.
