Simpson 3/16" x 8-1/4" 2-Cutter Head SDS-Plus Carbide Drill Bit by Simpson Strong-Tie is a premium-quality, professional-grade rotary hammer drill bit engineered for precision concrete, masonry, and hard material drilling. Manufactured in Germany to the highest industry standards, this hardened steel bit with a carbide-tipped 2-cutter head delivers consistent performance in demanding jobsite conditions. Whether you are driving anchors, setting fasteners, or drilling through concrete for structural connections, this SDS-Plus bit is built to hold tight tolerances and keep pace with high-volume drilling work.

Key Features

• Carbide-Tipped 2-Cutter Head - cuts efficiently through concrete and masonry, reducing bit walk and improving drilling speed compared to lower-grade tip configurations
• SDS-Plus Shank - locks securely into SDS-Plus rotary hammer chucks for tool-free bit changes and reliable torque transfer, eliminating slippage during heavy-duty drilling
• 3/16" Diameter - matches common anchor and fastener pilot hole requirements, making this bit a go-to choice for precisely sized anchor installations
• 6" Drilling Depth - provides sufficient embedment depth for structural and anchor applications requiring deep, clean holes in concrete or masonry
• 8-1/4" Overall Length - extra reach beyond the drilling depth accommodates thick materials and obstruction clearance, giving installers more flexibility in tight or layered assemblies
• Hardened Steel Construction - delivers lasting durability under repeated hammer action, reducing wear and extending service life on the jobsite
• Proprietary Design Features - incorporates design elements that enhance durability and drilling speed while improving ease of use, so professionals can work faster with less fatigue
• Manufactured in Germany to Precise Tolerance Requirements - ensures hole diameter consistency critical for proper anchor seating and structural integrity

Why This Product

• Designed by Simpson Strong-Tie specifically to meet precise tolerance requirements, this bit produces consistently sized holes that support reliable anchor performance in concrete and masonry - reducing the risk of under- or oversized holes that can compromise structural connections.
• The SDS-Plus shank is compatible with a broad range of professional rotary hammer tools, making this bit a practical fit for crews already invested in SDS-Plus tooling without requiring an additional chuck adapter or special equipment.
• With a 6" drilling depth on an 8-1/4" overall length, this bit handles installations where material thickness or layered assemblies demand deeper reach - giving contractors the flexibility to drill through concrete slabs, block, or other hard substrates in a single pass.
• As part of Simpson Strong-Tie's professional-grade drill bit line - manufactured in Germany to the highest industry standards - this bit is built for repeated, high-volume use, supporting contractors who depend on consistent tool performance across multiple projects.

Frequently Asked Questions

What type of rotary hammer is this bit compatible with?

This bit features an SDS-Plus shank, which is the standard connection type used by a wide range of professional rotary hammer tools. The SDS-Plus design locks into the chuck for secure, tool-free bit changes and efficient energy transfer during hammering and rotation.

What is the maximum drilling depth this bit can achieve?

This bit provides a drilling depth of 6 in. The 8-1/4 in. overall length allows the bit to extend past the drilled surface so the chuck clears the material, supporting full use of the 6 in. depth capacity in concrete, masonry, or similar hard substrates.

What advantage does a carbide-tipped 2-cutter head offer over standard bits?

The carbide tip resists wear from abrasive materials like concrete and masonry, maintaining a sharp cutting edge longer than non-carbide alternatives. The 2-cutter head geometry is designed to enhance drilling speed and durability, helping professionals complete holes faster and with greater consistency across repeated use.

Is this bit suitable for anchor installation applications?

Yes. At 3/16 in. diameter and with a drilling depth of 6 in., this bit is well-suited for drilling pilot holes for anchors and fasteners in concrete and masonry. Simpson Strong-Tie engineered these bits to meet precise tolerance requirements, which is critical for proper anchor seating and reliable load performance.
