Norton 61463624381 Mounted Point A5 36 Grit 1/4 in Shank

Product Description

The NORTON 61463624381 is a vitrified aluminum oxide mounted point in an A5 tree profile, designed for precision grinding and material removal on metal, castings, and hard surfaces. Rated at 36 grit, this very coarse abrasive removes stock aggressively, making it well suited for deburring, weld dressing, and surface prep work where fast cut is the priority. The vitrified bond holds abrasive grain firmly for consistent performance under load. It fits a standard 1/4-inch shank and is installed in a die grinder or rotary tool. At a maximum operating speed of 38,550 RPM, it handles demanding shop and field grinding tasks efficiently.

This mounted point is intended for use in metalworking, fabrication, foundry, and maintenance applications where a handheld rotary tool is required to reach confined or irregular geometry. The A5 tree shape is particularly effective for grinding internal radii, port work, and contoured surfaces that flat or cylindrical wheels cannot access. Typical installers include machinists, welders, pipefitters, and general maintenance mechanics working in both shop and field settings.

Key Features

• A5 tree profile for grinding contoured surfaces, ports, and internal radii
• 36 grit very coarse aluminum oxide for aggressive stock removal
• Vitrified bond construction for rigid, consistent grain retention under load
• Hard density grade maintains shape during heavy grinding passes
• 1/4-inch shank diameter fits standard die grinders and rotary tools
• Maximum rated speed of 38,550 RPM suitable for high-speed pneumatic and electric tools

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch shank mounted point. Verify that the tool spindle speed does not exceed the 38,550 RPM maximum rating before use.

Installation Notes

Mounting and removal of this abrasive point must be performed with the die grinder powered off and disconnected from the air supply or electrical source. Secure the shank fully into the collet before tightening the collet nut. Always verify the tool RPM rating does not exceed the 38,550 RPM maximum marked on the wheel. Eye protection and appropriate PPE are required when operating any mounted abrasive point; follow ANSI B7.1 safety standards for abrasive wheel use.
