Norton 61463624388 A12 Mounted Point 60 Grit 1/4 in Shank

Product Description

The NORTON 61463624388 is an A12 pointed tree mounted point designed for precision grinding, deburring, and surface blending in hard-to-reach areas. It uses an aluminum oxide abrasive bonded with a vitrified bond for consistent stock removal on ferrous metals and general-purpose materials. The wheel measures 1-1/4 inches thick and mounts on a 1/4-inch diameter shank with a 1-1/2-inch shank length. Rated at a maximum of 38,050 RPM, it operates at medium grit (60) and medium hardness density, making it well suited for moderate material removal without excessive surface damage. Licensed machinists, tool and die technicians, and maintenance grinders are the typical installers.

This mounted point fits standard die grinders and rotary tools equipped with a 1/4-inch collet. The A12 pointed tree profile provides access to contoured surfaces, slots, ports, weld seams, and internal bores where flat or straight wheels cannot reach. It is commonly used in fabrication shops, maintenance facilities, and production grinding operations on steel, cast iron, and similar ferrous workpieces. The vitrified bond maintains consistent abrasive exposure throughout the wheel's service life, supporting repeatable results across high-volume deburring and blending tasks.

Key Features

• A12 pointed tree shape for access to contoured and recessed surfaces
• 60-grit aluminum oxide abrasive for moderate stock removal on ferrous metals
• Vitrified bond provides consistent grit exposure and long wheel life
• Medium density and medium grade for balanced cut rate and surface finish
• Rated to 38,050 RPM for compatibility with standard die grinder speeds
• 1/4-inch shank diameter fits most die grinder and rotary tool collets

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch shank collet. Suitable for grinding and deburring ferrous metals including steel and cast iron in general industrial and maintenance applications.

Installation Notes

Mounted points must be installed and operated by qualified personnel familiar with abrasive wheel safety. Always power down and disconnect the grinder before inserting or removing the shank from the collet. Inspect the wheel for cracks or chips before each use and never exceed the rated maximum RPM marked on the product. Refer to ANSI B7.1 safety standards for proper mounting, guarding, and operating procedures for bonded abrasive wheels.
