3M 7010330818 Buff and Blend Ap Disc 4 Inch Medium

Product Description

The 3M 7010330818 is a Buff and Blend AP Disc designed for medium-duty surface finishing work on metal substrates. This non-woven abrasive disc uses an open web construction loaded with aluminum oxide mineral to deliver consistent scratch patterns without gouging or altering part geometry. The 4-inch diameter disc fits a 1/4-inch arbor and is graded Medium (MED, tan). It is typically installed and used by metalworkers, machinists, fabricators, and maintenance technicians who need controlled material removal with a predictable finish.

This disc is suited for cleaning, edge deburring, and antique finishing applications on a wide range of metals, including ferrous alloys. The medium grade makes it appropriate for general-purpose surface prep and light stock removal where a finer finish is not yet required. It can be used dry or with a lubricant to help flush swarf and reduce the risk of smearing the workpiece surface.

Key Features

• Open web construction is flexible and pliable, preventing gouging and maintaining part geometry
• Aluminum oxide mineral is friable, continuously exposing sharp cutting edges for a consistent scratch pattern
• Load-resistant open web resists clogging with debris, extending disc service life
• Compatible with lubricants to reduce swarf buildup and substrate smearing
• Medium (MED, tan) grade for general cleaning, deburring, and antique finishing
• 4-inch diameter with 1/4-inch arbor mount for use on standard die grinders and similar tools

Compatibility

Designed as an OEM-style replacement and standard fitment for 4-inch arbor-mount abrasive disc applications on die grinders and right-angle tools accepting a 1/4-inch arbor.

Installation Notes

This disc is installed by metalworkers, fabricators, and maintenance technicians using standard die grinders or right-angle tools with a 1/4-inch arbor. Ensure the tool is fully powered down and disconnected from the power source before mounting or removing the disc. Inspect the disc for damage before each use and confirm the tool RPM rating meets or exceeds the disc rating. When using a lubricant, select a product compatible with the substrate material to avoid contamination.
