Simpson 3/16" x 4-1/4" 2-Cutter Head SDS-Plus Carbide Drill Bit is a premium-quality, professional-grade rotary hammer drill bit engineered to deliver precise, fast drilling in concrete, masonry, and hard base materials. Manufactured in Germany to the highest industry standards for Simpson Strong-Tie, this carbide-tipped SDS-Plus bit incorporates proprietary design features that boost drilling speed, extend tool life, and reduce operator fatigue - making it a reliable choice for demanding installation work on job sites and in the field.

Key Features

• 2-Cutter Head design - delivers efficient material removal and faster penetration rates through concrete and masonry, reducing drilling time on high-volume installations
• Carbide-tipped cutting edge - resists wear against abrasive aggregate materials, extending bit life and maintaining sharp, consistent performance over repeated use
• SDS-Plus shank - locks securely into any SDS-Plus rotary hammer for reliable torque transfer and quick tool-free bit changes, compatible with a wide range of professional rotohammers
• 3/16" diameter - sized to create precise anchor and fastener pilot holes that meet tight tolerance requirements for structural and anchoring applications
• 4-1/4" overall length with 2" drilling depth - provides the reach and depth needed for standard anchor installation while keeping the bit compact and manageable in tight spaces
• Hardened steel body - provides a rigid, durable shank that withstands the rotational and impact forces of SDS-Plus hammer drilling without flexing or breaking
• Manufactured in Germany to precise tolerances - ensures consistent hole diameter and depth accuracy, which is critical for proper anchor seating and load performance

Why This Product

• Engineered specifically to meet the precise tolerance requirements demanded by structural anchoring applications - so holes are consistently sized for reliable fastener engagement and load transfer
• The carbide-tipped 2-cutter head combines durability and speed in a single bit, reducing the need to stop and replace worn bits mid-project on concrete or masonry surfaces
• SDS-Plus shank compatibility means this bit fits a broad range of professional rotary hammers from multiple manufacturers, eliminating the need for adapter accessories or specialized tools
• Part of a complete Simpson Strong-Tie drilling system - designed to work alongside Simpson anchors, fasteners, and installation tools for a consistent, code-compliant workflow

Frequently Asked Questions

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

This bit features an SDS-Plus shank, which is compatible with all current and older SDS-Plus rotohammers from manufacturers such as AEG, Black & Decker, Bosch, DeWalt, Hitachi, Hilti, Kango, Makita, Metabo, Milwaukee, Porter Cable, Ramset, Red Head, Ryobi, and Skil. The SDS-Plus system locks the bit securely for efficient torque and impact energy transfer.

What is the maximum drilling depth this bit can achieve?

This bit provides a drilling depth of 2 inches. The overall length of the bit is 4-1/4 inches, which includes the shank length held in the chuck. Always verify that the required embedment depth of your anchor or fastener does not exceed the 2-inch usable drilling depth.

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

The carbide-tipped 2-cutter head is designed for drilling into hard base materials such as concrete and masonry. Carbide tips retain their cutting edge against abrasive aggregate, making this bit well suited for anchor installation and other structural drilling tasks in cured concrete and similar hard substrates.

How does the 2-Cutter Head design benefit drilling performance?

The 2-cutter head geometry is engineered by Simpson Strong-Tie to incorporate proprietary features that enhance drilling speed and durability while improving ease of use. The cutting geometry removes material efficiently, which reduces heat buildup and operator fatigue compared to less optimized tip designs.
