Frequently Asked Questions

What type of rotary hammer is this bit compatible with?

This bit features an SDS-Plus shank, which is the standard interface for SDS-Plus rotary hammers. This shank type provides a secure locking fit and allows for quick, tool-free bit changes on any rotary hammer equipped with an SDS-Plus chuck.

What is the maximum drilling depth this bit can achieve?

This bit is designed for a drilling depth of 4 inches. The 6-1/4" overall length provides the necessary reach to achieve that embedment depth while maintaining proper engagement with the rotary hammer chuck.

Why is the 2-Cutter Head design beneficial for masonry drilling?

The 2-Cutter Head configuration helps efficiently remove material during drilling, which aids in maintaining the intended 5/32" hole diameter in concrete and masonry. This consistency is especially important when drilling holes for anchors and fasteners that require a precise fit.

How does the carbide tip contribute to the performance of this drill bit?

The carbide-tipped cutting edge is significantly harder than standard steel, which allows it to resist wear when drilling through abrasive materials like concrete and masonry. This helps the bit maintain its cutting efficiency over extended use and contributes to the professional-grade durability that the Simpson Strong-Tie line is designed to deliver.
