Arc Abrasives 31463 Surface Conditioning Disc 3in 36 Grit

Product Description

The ARC ABRASIVES 31463 is a 3-inch, Type S surface conditioning disc engineered for demanding edge grinding and surface prep work on metal. The disc features an extremely flexible backing paired with a 100 percent cotton abrasive construction, giving it the conformability needed to follow contours and tight edges without loading or glazing. At 36 grit, it delivers aggressive stock removal suitable for initial surface conditioning passes on cold rolled mild steel and stainless steel sheet. Licensed HVAC and sheet metal fabricators, welders, and metal finishers who work with light-gauge sheet stock will find this disc well-suited to production-level throughput.

This disc is designed for edge grinding applications on cold rolled mild steel and stainless steel sheet. The Type S quick-change attachment style makes it compatible with standard Type S mandrels, allowing fast disc swaps without additional tooling. The 36-grit cut rate makes it most appropriate as an aggressive conditioning disc in workflows where surface prep speed matters more than final finish refinement. It is sold individually, with a minimum order quantity of 50 units, making it a practical stocking item for shops that run high disc turnover.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source.
