Medium-Face Crimped Wheel Brush
The Pferd 81122 is a 7-inch crimped wheel brush built for medium to heavy-duty surface conditioning on bench grinders or automated equipment. Its carbon steel wire construction suits general metal fabrication, weld cleaning and deburring tasks where consistent material removal is required.
Gang-Mount Flush-Fit Design
Metal components and adapters are engineered for a flush fit when multiple brushes are gang mounted, eliminating gaps that cause uneven wear. This ensures a seamless surface finish across wider workpieces and reduces setup time for high-volume operations.
6000 RPM Speed Limit with 1-5/16 Trim
The brush runs at up to 6000 RPM with a 31/32-inch face width and 1-5/16-inch trim length, providing aggressive cutting action on flat or contoured surfaces. It is not suited for applications exceeding the rated speed or for fine finishing that demands softer wire grades.

Questions about this item
How often will the .014 carbon-steel wire need replacing?
Wire life depends on material hardness and pressure applied; inspect the 1-5/16 trim length regularly and replace the brush once wires are worn down to the hub.
What limits continuous operation at 6000 RPM?
The 6000 RPM maximum speed is the hard limit; exceeding it risks wire breakage and unsafe vibration, so the grinder must never run faster.
How much heat builds up when the 7-inch wheel runs all day?
Friction at the 31/32 face width generates noticeable heat on the workpiece; use light pressure and pause periodically to let both brush and metal cool.
