The Milwaukee Shockwave 48-89-4618 is an impact-duty titanium drill bit engineered to withstand the rigorous demands of power drilling and impact driver use. With its 21/64-inch diameter and durable titanium coating, this twist flute bit delivers precision performance across metal, wood, and plastic applications. The titanium coating provides up to three times the life of standard black oxide bits and is designed to stay sharper longer.
Designed with a variable helix geometry featuring an aggressive 35-degree helix angle that transitions to 15 degrees, this bit excels at rapid chip removal and limits heat buildup during drilling. The 135-degree split point tip delivers a precision start and prevents bit walking, ensuring fast and accurate hole placement. Built for impact-duty applications, this Milwaukee bit handles the shock loads of cordless impact drivers and conventional drills alike.
