Product Description
Milwaukee SHOCKWAVE 5-Piece SAE Impact Drill and Tap Set
Model Number: 48-89-4874
The Milwaukee 48-89-4874 is a SHOCKWAVE 5-Piece SAE Impact Drill and Tap Set — an impact-rated combination set for drilling and tapping SAE threaded holes with an impact driver or drill in metal, providing a complete solution for adding or restoring machine threads in steel, aluminum, and other metals without the manual hand tapping that is slow and physically demanding in production or repetitive tapping operations. Each piece in the set includes a drill bit matched to the correct tap drill size for the corresponding SAE thread specification plus the tap itself — the drill bit creates the correct root diameter hole for the thread depth, and the impact-rated tap cuts the thread form in the hole without the tap breakage that standard hand taps experience when driven by an impact driver's rotational impact energy. Milwaukee builds SHOCKWAVE impact drill and tap sets from materials specifically engineered for the torsional impact loads of impact driver use — the taps' geometry and steel specification absorb the impact driver's rotational impacts without the brittle fracture mode that makes standard hand taps unsuitable for power tool use.
The 5-piece SAE set covers the most commonly used SAE thread specifications encountered in automotive, mechanical, and equipment maintenance work where imperial thread standards are used. The impact-rated tapping capability transforms the time-consuming hand tapping operation into a fast, consistent powered process — particularly valuable in production repair, equipment restoration, and maintenance work where multiple tapped holes are required per project. Always use cutting oil during tapping operations and clear chips periodically for clean, accurate threads.
