3M 7000028449 | Scotch-Brite 1/2" Hole Diameter x 6" OAD x 1/4" Width Fine Grade Silicon Carbide EXL Unitized Wheel

Description

The 3M 7000028449 Scotch Brite EXL unitized wheel is a fine grade, silicon carbide abrasive wheel made for consistent edge finishing, deburring and light polishing of metal alloys, plastics and composites. This 6" OAD x 1/4" width unitized wheel delivers a conformable contact face that follows complex part geometries while limiting heat build up and smearing. The layered, unitized construction operates bi-directionally and can be dressed for extended service life and precise edge control. Designed with a 1/2" center hole for secure mounting, the Scotch Brite EXL fine grade wheel balances cut rate and finish quality in robotic or manual processing. Use it where repeatable, measurable edge refinement and surface conditioning are required.

Product Features and Benefits

Dressable wheel edge for precise deburring

The 1/2" hole abrasive wheel edge can be dressed to maintain a sharp profile for consistent burr removal and controlled edge radiusing on metals and composites.

Soft, conformable unitized construction

Silicon carbide deburring wheel’s conformability keeps the abrasive in contact with complex parts, improving finish uniformity without excessive material removal.

Silicon carbide mineral for fine finishing

Fine grade silicon carbide abrasive wheel provides high cut consistency and effective refining on hard alloys and non-ferrous substrates.

Bi directional operation for process flexibility

Layered unitized design works clockwise or counterclockwise, enabling versatile use in automated and hand held equipment.

Minimized heat and smear

Open unitized structure reduces heat build-up and resists smearing, preserving metallurgical properties and reducing rework.
