Norton 61463624380 Mounted Point A4 60 Grit Medium

Product Description

The NORTON 61463624380 is an A4 tree-shaped mounted point designed for precision grinding, deburring, and surface blending in hard-to-reach areas. It uses aluminum oxide abrasive bonded with a vitrified bond for consistent cutting action and long wheel life. The 60-grit medium-grade construction removes material efficiently while leaving a workable surface finish. At a maximum rated speed of 28,550 RPM, this mounted point is suited for use with die grinders and rotary tools common in metal fabrication, toolroom work, and maintenance grinding applications.

This mounted point fits standard die grinder collets accepting a 1/4-inch shank. The A4 tree profile allows access to contoured surfaces, internal radii, grooves, and tapered bores where flat or cylindrical wheels cannot reach. It is commonly used in metal fabrication shops, weld cleanup operations, mold and die work, and general maintenance grinding. The medium grade and 60-grit designation make it appropriate for steel, cast iron, and similar ferrous materials requiring moderate stock removal.

Key Features

• A4 tree point shape for access to contoured and recessed surfaces
• 60-grit medium grade aluminum oxide abrasive for efficient stock removal on ferrous metals
• Vitrified bond provides consistent cutting action and shape retention
• 28,550 RPM maximum speed rating for use with standard die grinders
• 1/4-inch shank diameter fits common die grinder and rotary tool collets
• Brown aluminum oxide abrasive, suitable for general-purpose ferrous grinding

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch shank collet. Appropriate for grinding ferrous metals including steel and cast iron in toolroom, fabrication, and maintenance grinding applications.

Installation Notes

Installation and use should be performed by qualified machinists, fabricators, or maintenance technicians familiar with abrasive grinding wheel safety. Before mounting, verify the die grinder or rotary tool is rated at or below the 28,550 RPM maximum speed of this mounted point. Secure the shank fully in the collet and tighten per the tool manufacturer's specifications. Always use appropriate eye protection and follow ANSI B11 and OSHA abrasive wheel safety guidelines during operation.
