Abrasive wheel for surface finishing

The 3M 14750 is a unitized wheel built for deburring, blending and light finishing on metal surfaces. Its non-woven silicon-carbide construction resists loading while delivering a consistent fine finish. The wheel measures three inches in diameter with a quarter-inch face width and mounts on a three-eighths inch unthreaded hole.

Suited for controlled hand-tool work

This wheel suits technicians and fabricators who need a soft-density abrasive for contour finishing on portable tools rated to 12,100 RPM. It is not intended for heavy stock removal, aggressive grinding or use on stationary machines that exceed the stated speed limit.

Maximum operating speed 12,100 RPM

The single figure that determines safe fitment is the 12,100 RPM maximum operating speed. The operator must confirm the tool spindle speed does not exceed this value before mounting the wheel.
