Milwaukee 48-07-0100 Morse Taper Arbor 3/4 Inch

Product Description

The MILWAUKEE 48-07-0100 is a No. 3 Morse Taper arbor with a 3/4-inch shank, designed as a replacement drive component for Milwaukee Selfeed bits 3 inches and larger. The arbor connects the bit to the drill or bit extension, transmitting torque during large-diameter boring operations in wood framing, rough carpentry, and utility installation work. At 0.79 pounds, it is a direct OEM-spec replacement intended to restore full performance when the original arbor shows wear from heavy, repeated use. Electricians, plumbers, and general contractors rely on this part to keep Selfeed drilling operations running without downtime.

This arbor is sized for Milwaukee Selfeed bits at 3 inches and above, making it a common replacement on jobsites where large-diameter holes are bored through dimensional lumber, engineered wood, and similar structural materials. It is sold individually and is a direct fit for the Milwaukee Selfeed bit system. Install this replacement when the existing arbor shows visible wear, slippage, or reduced bit retention during operation.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with drill accessory components. Disconnect the drill from its power source and remove the battery or unplug the tool before servicing any drive components.
