Milwaukee 48-20-7454 Sds Plus Drill Bit 3/8 X 12 in

Product Description

The MILWAUKEE 48-20-7454 is a 2-cutter SDS Plus rotary hammer drill bit designed for drilling in general concrete, hard aggregate, and rebar-reinforced concrete. Measuring 3/8 inches in diameter with a 12-inch overall length and 10-inch usable drilling depth, this bit is built for both corded and cordless rotary hammer applications. A variable flute geometry maximizes debris extraction for sustained drilling speed, while a reinforced flute design reduces vibration and extends service life. Licensed contractors, concrete trades, and masonry professionals use this bit for anchor hole drilling, core layout marking, and structural penetrations.

This bit suits residential and commercial concrete drilling tasks where consistent hole diameter and durability under load are critical. The enhanced rebar guards and breaker point geometry are particularly suited to hard aggregate and rebar-heavy slabs. The variable flute design supports efficient chip removal in deep holes, maintaining performance throughout a cordless battery charge and reducing downtime on the job site.

Key Features

• 2-cutter SDS Plus shank for use in standard SDS Plus rotary hammers
• Variable flute design for maximum debris extraction and up to 20 percent more holes per charge in cordless rotary hammers
• Enhanced rebar guards increase durability in hard aggregate and rebar
• Breaker point pulverizes material for faster drilling speeds
• Centering tip enables exact spot drilling without bit walk
• Wear mark indicator signals when the bit no longer meets ANSI diameter requirements
• Reinforced flute minimizes vibration and adds structural durability to the bit body

Compatibility

Designed for use with SDS Plus rotary hammers, both corded and cordless, in general concrete drilling applications.

Installation Notes

Installation of this bit requires a rotary hammer with an SDS Plus chuck. Always wear eye protection and hearing protection when operating a rotary hammer. Confirm the bit is fully seated and locked in the chuck before drilling. Check the wear mark indicator periodically to verify the bit still meets ANSI diameter tolerances before use on code-critical anchor placements.
