Milwaukee 49-57-0020 Arbor Assembly No. 3 Morse Taper

Product Description

The MILWAUKEE 49-57-0020 is a quick-change arbor assembly designed for tang drive Steel Hawg annular cutters used in Milwaukee magnetic drill motors. The assembly includes the arbor, an oil hose, and a hand pump, providing a complete setup for lubricated cutting operations. The arbor features a No. 3 Morse taper shank, allowing secure, repeatable mounting in compatible Milwaukee mag drill units. It is intended for professional tradespeople including electricians, ironworkers, pipefitters, and general contractors who rely on magnetic drill rigs for structural steel and pipe work.

This arbor assembly is built for use in sustained, heavy-duty magnetic drilling applications where annular cutters are driven through steel plate, structural members, or pipe. The integrated oil hose and hand pump system delivers cutting fluid directly to the cutting surface, helping maintain cutter temperature and extending cutter life during continuous use. For best results, Milwaukee Hawg Wash cutting fluid is recommended with this assembly.
