Milwaukee 49-57-0025 Morse Taper Arbor Assembly

Product Description

The MILWAUKEE 49-57-0025 is a No. 3 Morse taper arbor assembly designed to adapt 3/4 inch Weldon-style shank annular cutters for use with Milwaukee electromagnetic drill motors and magnetic drill stands. The assembly bridges the gap between standard annular cutter shanks and the No. 3 Morse taper socket found in compatible Milwaukee drill motors and drill presses. It is a mechanical adapter — no electrical connection required — and is installed by qualified metalworking tradespeople performing structural steel fabrication, ironwork, or on-site drilling operations. The assembly ships as a complete kit and weighs 2.28 pounds.

This arbor assembly is intended for use in steel fabrication and ironworking applications where magnetic base drilling is standard practice. It allows tradespeople to run 3/4 inch Weldon shank annular cutters on Milwaukee electromagnetic drill motors and drill presses without sourcing a separate adapter. Typical install scenarios include column drilling, beam drilling, and plate work on job sites or in fabrication shops.
