Milwaukee 48-20-7530 Sds-plus Drill Bit 1/4 in Carbide

Product Description

The MILWAUKEE 48-20-7530 is a 2-cutter SDS-Plus rotary hammer drill bit designed for drilling into general concrete, hard aggregate, and rebar-dense masonry. Built on the M/2a platform, this 4-flute, carbide-tipped bit measures 1/4 inch in diameter with a 2-inch usable length and 4-1/2-inch overall length. A variable flute geometry maximizes debris extraction, delivering up to 20% more holes per battery charge in cordless rotary hammers. Enhanced rebar guards and reinforced flutes extend service life and reduce vibration during operation. Licensed HVAC technicians, plumbers, electricians, and general trade contractors installing anchors, hangers, and penetrations through concrete will find this bit suited for both corded and cordless SDS-Plus rotary hammers.

This bit is intended for use in residential and commercial concrete drilling applications where anchor holes, conduit penetrations, or mechanical system supports must be bored through standard concrete and hard aggregate. The centering tip allows accurate spot drilling without walking, and a wear mark indicator shows when the bit diameter no longer meets ANSI requirements, taking the guesswork out of bit retirement decisions. The bit ships in a single-piece pack with a minimum order quantity of one.

Installation Notes

Installation of this bit requires an SDS-Plus chuck rotary hammer. Ensure the hammer is powered off and the battery is removed or the tool is unplugged before inserting or removing the bit. Confirm the bit is fully seated and locked in the chuck before drilling. Always follow applicable OSHA and site safety guidelines when drilling into concrete, including use of appropriate dust control measures.
