Surface-Conditioning Belt for Detail Work
This 3M 08856 belt is a non-woven abrasive designed for surface conditioning rather than heavy stock removal. It suits metalworkers and fabricators who need to blend, finish, or clean surfaces on contoured or tight areas. The semi-flexible scrim backing conforms to irregular shapes without aggressive cutting. It is not for buyers who need rapid material removal or coarse grinding.
Very Fine Grade Aluminium Oxide
The very fine grade aluminium oxide abrasive handles light deburring, blending tool marks, and preparing surfaces for coating. Its load-resistant resin bond reduces clogging on soft metals or painted surfaces. The 18 inch length fits compatible portable belt sanders. It runs out when the non-woven fibres wear smooth and no longer produce a consistent scratch pattern.
Cool Running with Low Loading
The open non-woven structure and resin bond dissipate heat during extended use, keeping the workpiece cooler than coated abrasive belts. Load resistance maintains cutting action on aluminium, stainless steel, and composites without frequent belt changes. The semi-flexible backing transmits less vibration to the tool and operator. It draws only the power required by the sander motor at operating speed.

Questions about this item
Will the 18 in belt fit the sander I already own?
Measure your machine's belt path; the 08856 is 18 in long and 1/2 in wide, so it matches any sander that takes that exact size.
How can I confirm the 08856 is cutting properly once installed?
Run the belt at operating speed; the blue non-woven surface should produce a consistent satin finish without loading or glazing on the workpiece.
Does the 08856 come with any adapters or mounting hardware?
The box contains only the single 1/2 in x 18 in non-woven belt; no adapters, tension springs or tracking guides are included.
