Norton 61463624391 Mounted Point A15 60 Grit Medium

Product Description

The NORTON 61463624391 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in metalworking applications. Shaped as a cylinder (Point Shape Code A15), this mounted point measures 1-1/16 inches in thickness and mounts on a 1/4-inch diameter shank that is 1-1/2 inches long. The 60-grit, medium-grade abrasive provides a balance of stock removal and surface refinement. The vitrified bond construction delivers consistent cutting action and holds its form under moderate heat. A maximum operating speed of 50,510 RPM allows use with standard die grinders and rotary tools commonly found in machine shops, fabrication facilities, and maintenance departments.

This mounted point is suited for internal diameter grinding, port work, weld blending, and hard-to-reach deburring tasks on ferrous and non-ferrous metals. The cylinder profile is effective on flat internal surfaces and shoulders where a consistent flat contact area is needed. It is a standard choice for machinists, tool-and-die makers, and maintenance technicians working on castings, forgings, and fabricated assemblies. The 1/4-inch shank fits directly into most die grinders and flexible shaft machines without an adapter.

Key Features

• Cylinder shape (A15) provides flat, consistent contact on internal and recessed surfaces
• 60 grit, medium grade aluminum oxide abrasive for balanced stock removal and finish
• Vitrified bond for controlled cutting action and thermal stability
• 1/4-inch shank diameter fits standard die grinder collets
• Rated to 50,510 RPM for use with high-speed rotary tools
• Lightweight at 0.1197 pounds for reduced operator fatigue during extended use

Compatibility

Designed as an OEM-style replacement or direct-use mounted point compatible with die grinders and rotary tools accepting a 1/4-inch collet or chuck.

Installation Notes

Mounted points must be installed by trained personnel familiar with abrasive tool safety standards such as ANSI B7.1. Before mounting, confirm the spindle speed of the tool does not exceed the 50,510 RPM rating marked on the point or packaging. Power down and disconnect the tool from its power source before changing the mounted point. Never force the shank into an undersized collet or overtighten the collet nut beyond hand-firm plus the wrench snug recommended by the tool manufacturer.
