Product Description
Milwaukee 1-3/8 in. Switchblade Self-Feed Bit 3-Blade Replacement Kit
Model Number: 48-25-5220
The Milwaukee 48-25-5220 is a 1-3/8 in. Switchblade Self-Feed Bit 3-Blade Replacement Kit — providing three replacement cutting blades for the Milwaukee 1-3/8 in. Switchblade self-feeding wood boring bit in a convenient self-contained storage case that keeps all the tools needed for blade changes organized and accessible at the work site. The Milwaukee Switchblade bit system uses interchangeable cutting blade inserts that snap in and out of the bit body using a tool-free push-button mechanism, allowing field blade replacement without tools in approximately 10 seconds — eliminating the need to carry sharpened spare bits or return to the service vehicle for a replacement bit when the cutting blade dulls during drilling. When the Switchblade's cutting blade reaches the end of its useful sharpness, the worn blade is removed and a fresh blade from this replacement kit is snapped in, restoring full drilling performance immediately at the work location.
The 1-3/8 in. diameter is used for larger cable management holes, 1 in. EMT conduit rough-in penetrations, medium-diameter plumbing rough-in holes, and firestop grommet installations where the larger bore diameter matches the specified grommet outer flange dimensions. The Switchblade system's tool-free blade replacement mechanism is specifically engineered for professional rough-in environments — electricians, plumbers, and HVAC installers who drill continuously throughout a project need to minimize the time spent on blade maintenance and replacement activities that interrupt production drilling pace. Three replacement blades in a single kit provides a substantial supply of fresh cutting capability for extended use on large-scale rough-in projects. The storage case keeps blades organized and protected between uses, preventing the blade edge damage that occurs when loose blades contact other metal tools and hardware in a tool bag.
Switchblade replacement kits are available in sizes from 1-3/8 in. through 2-9/16 in. to match every Switchblade bit diameter in Milwaukee's self-feed bit lineup, and in 1-blade, 3-blade, and 10-blade kit quantities for different project scale and supply requirements.
