Mill-rose BM-66472 Hex Shank Power Fitting Brush 1-1/4 X 1-3/8 in

Product Description

The MILL-ROSE BM-66472 is a hex shank power fitting brush from the 6600 Series, designed for use with power drills and presses in plumbing and mechanical trade applications. The brush measures 1-1/4 inches ID by 1-3/8 inches OD and features high-carbon or stainless steel bristles built for extended service life under powered operation. The hex shank provides positive chuck engagement, reducing slippage during aggressive cleaning passes. Plumbers and pipefitters reach for this tool when prepping fittings, tubing, and drill holes before solder, press, or threaded assembly. The bristle construction is reinforced for greater strength and longer wear compared to standard hand brushes.

This brush handles quick cleaning of copper, brass, stainless steel, soft steel, aluminum, and plastic surfaces. It is well-suited for deburring and surface prep on tubing and fittings in residential and light commercial plumbing, HVAC refrigerant piping, and general mechanical work. The 1-1/4 inch ID fits standard fitting bores in that size range, making it a direct grab for technicians working on common pipe and fitting sizes. Applicable wherever a power drill or drill press is the preferred tool for surface prep speed.

Installation Notes

Install into a drill chuck or press chuck by seating the hex shank fully before tightening.
