Freud DMAST1050 Sds-plus Stop Bit 5/8 X 2-1/16 Inch 5 Pack

Product Description

The FREUD DMAST1050 is a carbide-tipped SDS-plus hammer stop bit designed for fast, accurate drilling in concrete. The bit measures 5/8 inch in diameter with a 2-1/16 inch usable length and features a 2-cutter geometry for aggressive material removal. A fixed stop collar sets a predetermined drilling depth, making it well suited for repetitive shallow anchor installations where consistency matters. The carbide tips are processed through a proprietary brazing and hardening method that extends cutting life and maintains accuracy across a high volume of holes. This bit is optimized for use in both corded and cordless SDS-plus rotary hammers.

This stop bit is intended for concrete drilling applications where anchors require a controlled, uniform hole depth. It is commonly used in commercial and residential construction, concrete fastening work, and structural anchoring tasks. The stop collar eliminates the need for tape or depth gauges during repetitive installations, improving workflow efficiency on the job site. Each package contains 5 bits, supporting production-level anchoring work or providing backup inventory for ongoing projects. Licensed contractors, concrete sub-contractors, and experienced tradespeople working with rotary hammers will find this bit compatible with standard SDS-plus chuck systems.

Installation Notes

Install this bit in an SDS-plus rotary hammer according to the tool manufacturer's chuck engagement procedure before beginning any drilling.

Confirm the stop collar is properly seated and secure before starting a drilling sequence to ensure consistent depth across all holes. Follow applicable OSHA standards and job-site safety requirements when drilling into structural concrete.
