3M 7000144151 Deburring Disc 4 in Very Coarse Silicon Carbide

Product Description

The 3M 7000144151 is a silicon carbide deburring disc designed for aggressive material removal on metal, plastic, and composite surfaces. At 4 inches in diameter with a 1/4-inch center arbor hole, this disc mounts directly to compatible right-angle grinders and deburring tools. The very coarse grade cuts quickly through burrs, flash, and sharp edges left after machining, stamping, or cutting operations. Rated to 6000 RPM, it handles demanding production and maintenance tasks without sacrificing control. Machinists, fabricators, and maintenance technicians are the typical users in both shop and field environments.

This deburring disc is suited for metalworking applications where burr removal, edge blending, and surface preparation are required before assembly, coating, or inspection. Its silicon carbide abrasive material makes it effective on harder metals and non-ferrous materials. The arbor-mount configuration simplifies tool changes and keeps the disc securely seated during high-speed operation. It fits standard deburring and finishing operations in manufacturing, HVAC fabrication shops, pipefitting, and general metalwork settings.

Key Features

• 4-inch diameter disc provides broad contact area for efficient burr removal
• Very coarse grade for fast cutting on heavy burrs and rough edges
• Silicon carbide abrasive material suited for hard metals and non-ferrous surfaces
• 1/4-inch arbor center hole for secure, straightforward mounting
• 6000 RPM maximum speed rating supports high-throughput deburring work

Compatibility

Designed for use with right-angle grinders and deburring tools that accept a 1/4-inch arbor-mount disc. Confirm tool spindle speed does not exceed the 6000 RPM maximum rating before use.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive disc safety practices. Ensure the grinder or deburring tool is powered off and unplugged before mounting or removing the disc. Verify that the tool's maximum RPM rating meets or does not exceed the disc's 6000 RPM limit. Always use appropriate eye protection and guards in accordance with applicable ANSI abrasive safety standards.
