3M 7100074871 | 840357 Standard Abrasives 2" Diameter Medium Aluminum Oxide Quick Change Buff and Blend HS Disc

Description

The 3M 7100074871 Quick Change Buff and Blend HS Disc is a 2-inch industrial surface conditioning disc made for dependable deburring and finishing of irregularly shaped parts. The HS Medium disc, made of high-strength non-woven nylon with aluminum oxide mineral bonded into the web, provides a consistent, smear-free scratch pattern while resisting folding and fraying under high contact pressure. This Standard Abrasives Buff and Blend Disc is intended for use on metals such as stainless steel, brass, bronze, and aluminum. It performs edge breaking, light deburring, and satin/grain finishing without gouging the substrate. In offhand and automated finishing operations, quick-change attachments help maintain throughput by speeding up grade swaps. The disc, which is compatible with TR (Roloc-style) holder systems, strikes a balance between aggressive cutting and controlled finishing to produce consistent, measurable results.

Product Features and Benefits

High-strength non-woven nylon construction

Robust HS web resists tearing and folding, so the disc maintains stiffness on edges and contoured surfaces and gives predictable life under heavy contact pressures.

Aluminum oxide mineral for uniform cutting

Aluminum oxide bonded into the web produces a consistent scratch pattern ideal for satin or grain finishes while providing sharp, long-lasting cut performance.

Medium (MED) grade for balanced finishing

The 3M 7100074871’s MED grade offers a compromise between cut rate and final appearance, fast enough to remove burrs and tool marks, yet fine enough to produce clean, low-sparkle finishes.

Quick change (TSM) attachment for fast swaps

Quick-change fastening enables tool-free disc replacements and secure mounting at rated speeds, reducing downtime when switching grades or applications.

Load-resistant open web design

The open web construction of the 3M Quick Change Buff and Blend HS Disc sheds swarf and debris, allowing minerals to be exposed for longer periods of time, reducing clogging, maintaining cut rate, and reducing operator rework.
