Norton 61463686138 Cone Mounted Point 36 Grit 1/4 in Shank

Product Description

The NORTON 61463686138 is a ceramic abrasive mounted point designed for aggressive material removal on metals, welds, and hard surfaces. Shaped as an A3 cone, this mounted point operates at up to 16,100 RPM and delivers extra coarse, 36-grit cutting action suited for deburring, grinding, and surface conditioning in tight or contoured areas. The ceramic abrasive grain runs very hard and stays sharp under load, making it effective on high-tensile alloys and hardened steels. It mounts via a 1/4-inch diameter shank and is intended for use with die grinders and rotary tools in professional shop and fabrication environments.

This mounted point is well suited for metal fabrication shops, maintenance and repair operations, and industrial grinding applications where fast stock removal is required in confined spaces. The A3 cone shape makes it effective for working inside bores, chamfers, and contoured weld joints where flat or wheel-style abrasives cannot reach. It is a single-unit part intended for professional use by machinists, fabricators, and maintenance technicians.

Key Features

• A3 cone point shape for access to contoured and recessed surfaces
• 36-grit extra coarse ceramic abrasive for aggressive stock removal
• Maximum operating speed of 16,100 RPM
• 1/4-inch shank diameter compatible with standard die grinders
• Very hard density grade for durability on high-tensile materials
• Green ceramic grain stays sharp and cool under sustained load

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch shank. Suitable for grinding and deburring applications on metal, hardened steel, and similar hard materials.

Installation Notes

Installation is performed by qualified machinists or fabricators using a die grinder or compatible rotary tool with a 1/4-inch collet. Before mounting, ensure the tool is powered off and disconnected from the air supply or electrical source. Verify that the tool's rated RPM meets or exceeds 16,100 RPM before operation, and always inspect the mounted point for cracks or damage prior to use. Always wear appropriate PPE including eye protection when operating abrasive tools.
