Norton 61463624477 Mounted Point B131 Medium Fine

Product Description

The NORTON 61463624477 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and hard materials. This cylinder-shaped abrasive point carries a B131 shape code and is rated medium fine grade with medium density, making it well suited for controlled material removal and light finishing work. The 1/2 inch head thickness and 1/8 inch shank diameter make it compatible with standard rotary tools and die grinders. It is a single-piece unit sold individually and is a go-to consumable for machinists, tool-and-die workers, and metal fabricators who need consistent abrasive performance in tight or contoured areas.

This mounted point is used in applications where a standard bench grinder or flap disc cannot reach, including internal bores, slots, weld seams, and complex part geometries. It is suited for ferrous metals and harder workpiece materials common in maintenance, repair, and production grinding environments. The aluminum oxide abrasive grain is a proven general-purpose material for steel and cast iron work. The brown color identifies the standard aluminum oxide bond formulation used across this product family.

Installation Notes

Mounted points are installed and serviced by machinists, tool-and-die technicians, and metal fabricators. Always power down and disconnect the rotary tool or die grinder before changing mounted points. Inspect the shank for runout or damage before seating in the collet, and verify the tool RPM rating is not exceeded for the point size. Eye protection and appropriate PPE are required during operation.
