SKU CH-7S4R-351RK MPN 13719

A non-woven silicon-carbide unitized wheel for surface finishing at up to 5,000 RPM

  • TypeSanders
  • Fine finish with silicon carbide abrasive
  • Soft density reduces loading on contours
  • 6-inch diameter covers more surface per pass
  • 1/2-inch unthreaded hole fits common arbors
  • Rated for 5,000 RPM maximum operating speed

6 in Unitized Wheel

The 3M 13719 unitized wheel is a non-woven abrasive disc built for surface conditioning on metal, composites, and painted substrates. It mounts on straight-shaft tools via a 1/2 in unthreaded arbor hole and uses silicon-carbide grain in a soft-density, fine-grade matrix. The grey wheel carries the XL-UW series designation and is rated for 5,000 RPM maximum operating speed.

Finishers needing consistent blending without

Technicians who require a conformable wheel for light deburring, blending tool marks, or preparing surfaces for coating will find the soft density and fine grade suitable. Shops that need aggressive stock removal, heavy weld grinding, or high-pressure edge breaking should select a harder-density or coarse-grade alternative instead.

5,000 RPM maximum operating speed

This speed limit is the critical specification that determines whether the wheel matches the tool and the application. Running the disc above 5,000 RPM risks structural failure and unsafe operation. Always verify that the drive tool’s free speed does not exceed this figure before mounting the wheel.

Questions about this item

Will the 1/2 in unthreaded hole fit the arbor on my existing bench grinder?

The wheel has a 1/2 in unthreaded hole and no quick-change system, so it mounts directly on a matching arbor or adapter that you already use for 6 in wheels.

How can I confirm the wheel is running correctly once installed?

Run the wheel up to speed and check for smooth, vibration-free rotation; the maximum operating speed is 5,000 RPM, so do not exceed that limit on your machine.

Does the package include any mounting hardware or bushings?

The box contains only the gray silicon-carbide unitized wheel itself; any arbor bushings, flanges or adapters must be sourced separately.
