Milwaukee 48-20-7498 Sds-plus MX4 Carbide Bit Kit 5 Piece

Product Description

The Milwaukee Electric Tool Corp 48-20-7498 is a 5-piece SDS-Plus carbide rotary hammer bit kit built around the MX4 4-cutter platform. The 4-cutter 90-degree head design reduces bit lock-up in rebar and delivers up to four times the service life in rebar-heavy applications compared to standard bits. Breaker points accelerate penetration rates, while a centering tip allows precise spot drilling. Wear mark indicators signal end-of-life when the bit no longer meets ANSI requirements, giving installers a reliable benchmark for replacement before core quality degrades.

This kit is suited for residential and commercial concrete drilling applications using SDS-Plus rotary hammers. The variable flute geometry is engineered to deliver up to 20 percent more holes per battery charge on cordless rotary hammers, making it a practical choice for work sites where power access is limited. Enhanced rebar guards and reinforced flutes reduce vibration and extend bit body durability in repetitive concrete and masonry drilling operations. Electricians, plumbers, HVAC installers, and general contractors who core through concrete slabs and block walls are the primary users of this kit.

Installation Notes

SDS-Plus bits are installed and removed by licensed tradespeople and experienced mechanics without tools using the SDS-Plus chuck retention system. Always confirm the rotary hammer is powered off and the battery removed or the tool unplugged before changing bits. Wear eye and hearing protection during concrete and masonry drilling operations. Follow applicable OSHA and jobsite safety requirements when working near rebar or post-tension concrete.
