Description
The 3M 7000121031 Scotch-Brite EXL deburring wheel is a fine grade convolute wheel made for fast, controlled burr removal and high quality finishing. Constructed from a conformable non woven web with silicon carbide mineral and a proprietary resin system, this 4" x 3/8" wheel minimizes smearing while preserving surface integrity. Its dense, hard composition provides efficient deburring on metals, composites and glass, making the scotch brite exl deburring wheel ideal for stamped, laser cut and post sanding parts. Convolute layering ensures consistent operator feel and reduced pressure requirements to speed cycle times. Use this wheel when you need a repeatable, long life solution for off hand deburring and polishing tasks.
Product Features and Benefits
Fast, consistent deburring with silicon carbide
Silicon carbide abrasive removes burrs quickly while producing a controlled finish; the material is optimized for deburring and light polishing without undercutting. This ensures measurable, repeatable surface preparation results.
Conformable nonwoven convolute construction
3M 7000121031 features a layered convolute design that maintains a stable contact surface that conforms to part geometry and reduces operator fatigue during off-hand deburring operations.
Resin system reduces smearing and heat
The 3m scotch brite exl deburring wheel unique resin formulation minimises smearing on sensitive substrates and lowers heat transfer, reducing the risk of discoloration or warping on coated or heat-sensitive parts.
Designed for industrial production environments
4" diameter and 3/8" face width with center-hole attachment provide compatibility with common bench and hand arbors for efficient wheel changes and predictable throughput.

Frequently Asked Questions
What is a 3m scotch brite exl deburring & finishing wheel?
It is a conformable, silicon carbide nonwoven convolute wheel designed to deburr, blend and finish surfaces with low smear.
Is this an industrial deburring wheel suitable for production?
Yes, the 3M 7000121031 is specified for industrial deburring with consistent performance and extended service life.
What does fine grade convolute wheel mean?
Fine grade indicates the abrasive fineness; convolute refers to the layered construction that gives conformability and smooth operator feel.
Why choose a long life deburring wheel like this EXL wheel?
Long life construction reduces wheel changes and lowers per part abrasive cost while maintaining finish quality in high-volume use.
