Simpson 3/16" x 12" 2-Cutter Head SDS-Plus Drill Bit with Carbide Tip is a premium, professional-grade rotary hammer drill bit engineered for precision concrete, masonry, and anchor-setting applications. Manufactured in Germany to the highest industry standards, this carbide-tipped bit features an SDS-Plus shank for secure, tool-free chuck engagement and delivers reliable performance across a wide range of heavy-duty drilling tasks.

Key Features

• Carbide-Tipped 2-Cutter Head - the twin-cutter tip configuration maximizes cutting efficiency and chip clearance, reducing heat buildup and extending bit life in demanding concrete and masonry work.
• SDS-Plus Shank - the standardized SDS-Plus interface locks securely into rotary hammer chucks without additional tools, enabling fast bit changes and reliable torque transfer during heavy drilling.
• 3/16" Diameter with 10" Drilling Depth - the slim, precise diameter is ideal for anchor pilot holes and tight-tolerance installations, while the 10" usable drilling depth handles thick concrete and deep embedment requirements.
• 12" Overall Length - the extended overall length gives users increased reach when drilling into recessed or overhead surfaces without sacrificing control.
• Hardened Steel Construction - the body is built from hardened steel, providing the structural rigidity needed to withstand the repeated impact forces of rotary hammer operation without bending or premature wear.
• Proprietary Design Features - incorporates design elements that enhance durability and drilling speed while improving ease of use, so professionals can complete anchor-setting and drilling tasks faster and with greater confidence.
• Precise Tolerance Manufacturing - designed to meet precise tolerance requirements, ensuring consistently accurate hole diameters that are critical for Simpson Strong-Tie anchor and fastener installations.

Why This Product

• Engineered specifically for anchor and fastener applications - the 3/16" diameter and 10" drilling depth are sized precisely for Simpson Strong-Tie anchor systems, reducing the risk of oversized holes and ensuring proper load transfer at the fastened connection.
• Professional-grade durability in a rotary hammer format - the combination of carbide tip and hardened steel body means this bit holds up to repeated use in concrete and masonry without the tip degradation that shortens the life of lower-quality bits.
• Broad compatibility with SDS-Plus rotary hammers - the SDS-Plus shank interfaces with rotary hammers from all major tool brands, so contractors can use this bit with the tools already on the jobsite without adapters or modifications.
• German manufacturing to exacting standards - built to the highest industry standards, this bit is engineered to perform reliably on professional jobsites where precision and consistency are non-negotiable.

Frequently Asked Questions

What type of rotary hammer is this drill bit compatible with?

This drill bit features an SDS-Plus shank, which is the standard interface used by the vast majority of rotary hammers from major tool manufacturers. It locks into any SDS-Plus chuck for secure, tool-free bit installation and reliable performance during hammer drilling.

What is the difference between the drilling depth and the overall length?

The overall length of this bit is 12 inches, which is the full measurement from tip to shank end. The drilling depth is 10 inches, which represents the maximum usable depth the bit can reach within a hole. The difference accounts for the portion of the shank that remains inside the chuck during drilling.

What materials can this carbide-tipped SDS-Plus bit drill through?

Carbide-tipped SDS-Plus drill bits like this one are designed for drilling into concrete, masonry, block, and similar hard substrates. The carbide tip is specifically suited for the rotary hammer action required to penetrate these materials efficiently, and the 2-cutter head design promotes fast chip evacuation to keep the cutting edge clear.

Why is the 3/16" diameter important for anchor installations?

Precise hole diameter is critical when installing anchors and fasteners because an oversized hole can reduce the load capacity of the connection. This bit is designed to meet precise tolerance requirements, which helps ensure that the finished hole is accurately sized for proper anchor seating and reliable load performance in concrete and masonry applications.
