Freud DMAST1030 Sds-plus Stop Bit 1/2x1-11/16 in 5 Pack

Product Description

The FREUD DMAST1030 is a 1/2-inch by 1-11/16-inch SDS-Plus 2-cutter carbide-tipped hammer stop bit designed for efficient shallow anchor installations in concrete. The stop collar establishes a fixed stopping depth, eliminating guesswork and improving consistency when setting anchors. Carbide tips are processed through a specialized brazing and hardening method that extends cutting life and maintains hole accuracy under repeated use. This bit is optimized for performance in both corded and cordless SDS-Plus rotary hammers and is sold in a 5-piece pack. Licensed contractors and concrete tradespeople install this type of bit for anchor prep work on slabs, walls, and structural concrete.

This stop bit is suited for residential and commercial concrete drilling applications where shallow, consistent hole depth is required. Typical use cases include setting wedge anchors, sleeve anchors, and drop-in anchors in concrete floors, foundations, and masonry walls. The SDS-Plus shank interfaces directly with SDS-Plus rotary hammer chucks, making it compatible with a wide range of corded and cordless rotary hammer tools commonly found on job sites. The 2-cutter geometry promotes fast material removal while keeping hole diameter consistent throughout the bit's service life.

Installation Notes

Installation is performed by trained concrete and general trades contractors using SDS-Plus rotary hammers. Before drilling, confirm the work surface is clear of embedded conduit, rebar, or utilities. Wear appropriate PPE including eye protection and hearing protection when operating rotary hammers. Follow anchor manufacturer depth specifications and applicable building codes when setting fasteners in structural concrete.
