Norton 61463686139 Mounted Point 36 Grit Ceramic A1

Product Description

The NORTON 61463686139 is a ceramic abrasive mounted point in the A1 cone shape, designed for aggressive material removal on hard metals and alloys. It operates at up to 19,800 RPM and delivers extra coarse, 36-grit cutting action with a very hard density rating. The 1/4 inch shank fits standard die grinders and rotary tools used by machinists, tool-and-die workers, weld fitters, and fabricators. The ceramic abrasive grain self-sharpens during use, maintaining cut rate longer than conventional aluminum oxide in demanding grinding applications.

This mounted point is suited for internal grinding, deburring, port work, and weld blending in ferrous and high-alloy workpieces. The A1 cone shape provides access to bores, cavities, and contoured surfaces where flat or straight profiles cannot reach. Typical applications include die work, mold finishing prep, and heavy deburring in fabrication shops and maintenance environments. The green color coding identifies the ceramic grain type for quick identification on the shop floor.

Key Features

• A1 cone point shape for access to bores and contoured surfaces
• 36-grit extra coarse ceramic abrasive for aggressive stock removal
• Very hard density rating maintains shape under consistent pressure
• Rated to 19,800 RPM for use with standard die grinders
• 1/4 inch shank diameter fits common rotary and die grinder collets
• Self-sharpening ceramic grain sustains cut rate on hard alloys

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4 inch shank collet. Suitable for grinding ferrous metals, hardened steels, and high-alloy materials where extra coarse ceramic abrasion is required.

Installation Notes

Mounted points must be installed by a qualified operator familiar with abrasive tool safety. Confirm the die grinder or rotary tool RPM rating meets or exceeds 19,800 RPM before mounting. Inspect the point for chips or cracks before each use and discard if damage is found. Always wear appropriate eye protection and ensure the workpiece is secured before beginning grinding operations.
