4-1/2″ SDS-MAX Carbide Dry Core Bit

4-1/2″ SDS-MAX Carbide Dry Core Bit – 22″ Long

Large-Diameter Masonry Coring. Closeout Price.

This 4-1/2″ SDS-MAX carbide core bit offers an economical option for making larger openings in softer masonry. Its 12 carbide cutting teeth and 22″ overall length combine a large cutting diameter with extended reach—all at closeout pricing.

The SDS-MAX shank fits compatible rotary hammers rated for a 4-1/2″ carbide core bit. Intended for dry coring, with no separate shank adapter required on compatible equipment.

An economy tool for limited, light-duty work. Low upfront cost makes it a budget-conscious choice for masonry openings. For frequent drilling or demanding concrete applications, select a higher-grade core bit matched to the job.
