Milwaukee 1-1/2" Selfeed Drill Bit 48-25-5120
ROUGH-IN BORE SPEED DOMINANCE
When your crew is tackling high-volume rough-ins, the Milwaukee 48-25-5120 Selfeed Drill Bit is engineered to maximize throughput while minimizing technician fatigue. This isn't just a wood-boring accessory; it's a precision-machined solution for repetitive large-diameter holes in dimensional lumber. By utilizing a lead screw that actively pulls the bit through the substrate, this bit eliminates the need for manual down-pressure, allowing your high-torque drills to maintain optimal RPM and cooling efficiency. The geometry of the inside cutting plane shaves the hole radius for a surgical finish that won't snag pipe or conduit during pull-through, ensuring code-compliant installs every time.
- / CENTER FEED SCREW PILOT: Aggressively tracks into the grain to provide a self-feeding action that significantly increases boring speed.
- / RADIUS-SHAVING PLANE: Creates exceptionally clean, splinter-free holes without the need for excessive operator force.
- / 7/16 INCH HEX SHANK: Provides three flat gripping surfaces for the drill chuck to eliminate slippage and maximize torque transfer.
- / RESHARPENABLE GEOMETRY: Extends tool life indefinitely by allowing the edges to be touched up, maintaining a "like-new" cut for years of service.
- / RUST INHIBITOR COATING: Protects the integrity of the cutting edge against moisture and corrosive jobsite environments.
