Frequently Asked Questions

What type of rotary hammer is this bit compatible with?

This drill bit uses an SDS-Plus shank, which is the standard interface for SDS-Plus rotary hammers. The SDS-Plus connection allows tool-free bit insertion and provides a secure, positive drive during hammer drilling operations.

What is the maximum drilling depth this bit achieves?

This bit has a drilling depth of 4 inches. The 6-1/4" overall length provides the additional clearance needed above the surface while still reaching the full 4" drilling depth within the material.

Why does hole diameter precision matter when drilling for anchors or fasteners?

Simpson Strong-Tie designs this bit to meet precise tolerance requirements because anchor and fastener holding values depend on a correctly sized hole. An oversized hole can reduce the load capacity of an installed anchor, while a correctly sized hole ensures the fastener or anchor performs as specified.

What materials is this carbide-tipped SDS-Plus bit designed to drill into?

Carbide-tipped SDS-Plus drill bits are designed for use in concrete, masonry, block, and similar hard base materials where rotary hammer drilling is required. The carbide tip resists the abrasion and heat generated when drilling into these tough materials.
