3M 7100054448 Cross Buff 2in X 0.5in 2PLY High Strength Very Fine

Product Description

The 3M 7100054448 is a Scotch-Brite Cross Buff designed for cleaning and polishing inside diameters in precision production environments. Built with a high-strength, very fine (VFN) abrasive web and a 2-PLY staggered configuration, this cross buff delivers consistent contact across the bore surface for uniform results. The 8-32 arbor thread mounts the buff to standard rotary tooling, making it compatible with typical bench and machine setups. At 2 inches in diameter and 0.5 inches in width, the part is sized for tight inside-diameter work. Applications include deburring, satin finishing, denibbing, defuzzing, and surface cleaning. It is used in aerospace and automotive production lines where repeatable, controlled surface conditioning is required.

This cross buff is suited for production applications involving inside diameters such as lifter bores, valve bodies, valve spools, and tubing. It performs well on surface preparation tasks including removal of oxidation, rust, and corrosion prior to coating. Polishing of dies, molds, and precision bores is a common use case. The staggered 2-PLY web design maintains contact consistency across uneven or tight bore geometries, making it practical for both high-volume automated setups and manual finishing operations in aerospace and automotive shops.

Installation Notes

Mounting and operation of this cross buff should be performed by a qualified technician familiar with rotary abrasive tooling. Verify the spindle speed of the tool does not exceed the rated maximum for the buff before use. Wear appropriate eye protection and ensure workpieces are secured before initiating rotation. Inspect the buff for wear or separation before each use and replace if the web shows signs of degradation.
