SWITCHBLADE™ Selfeed Bit 2"

Milwaukee 48-25-5135 — SWITCHBLADE™ Selfeed Bit (2")

The Milwaukee 48-25-5135 SWITCHBLADE™ Selfeed Bit is a high-speed wood boring bit designed for rough-in drilling of large holes, typically used in framing, plumbing, electrical, and HVAC work.

It’s part of Milwaukee’s SWITCHBLADE system, which uses replaceable cutting blades instead of sharpening the entire bit, reducing downtime and extending tool life.

Key Features

• 2" cutting diameter
• Replaceable SWITCHBLADE™ cutting system (swap blades, not the whole bit)
• Aggressive self-feed screw pulls the bit through wood automatically
• Designed for fast, repetitive hole cutting in framing lumber
• Hardened steel blade system for extended life
• 7/16" hex shank for secure drill/impact compatibility

What it’s used for

• Drilling large holes for plumbing pipes
• Running electrical conduit and cable bundles
• HVAC and mechanical rough-in work
• Framing and construction layout drilling
• High-volume repetitive boring in wood structures

Why trades use it

This bit is built for speed and production work, not precision:

• Self-feeding screw reduces operator force
• Replaceable blades mean less downtime vs resharpening
• Cuts faster than standard auger or spade bits in structural wood
• Designed for repeated daily use on job sites
