Norton 66253344383 Abrasive Cone Type 16 Very Coarse 16 Grit

Product Description

The NORTON 66253344383 is a Type 16 abrasive cone designed for aggressive material removal on metal and other hard surfaces. Constructed from zirconia alumina, this cone delivers a very coarse, 16-grit cut that quickly clears weld flash, burrs, and surface scale. The 5/8-11 threaded arbor hole provides a secure, standardized mount on angle grinders and die grinders equipped with a matching spindle. With a maximum operating speed of 13,195 RPM, it is suited for sustained, high-load grinding work in fabrication, maintenance, and repair environments.

This abrasive cone is used in metal fabrication shops, industrial maintenance settings, and structural steel work where rapid stock removal is required. It is well suited for grinding inside pipe ends, contoured welds, casting gates, and hard-to-reach recesses that flat wheels cannot access. Licensed grinder operators and experienced metal fabricators are the primary users. The Type 16 cone geometry allows the tool to follow curved and irregular surfaces more effectively than a straight wheel.

Key Features

• Zirconia alumina abrasive grain for fast, aggressive cutting and extended wheel life
• Very coarse 16 grit for maximum material removal rate
• Type 16 cone shape reaches contoured surfaces, pipe interiors, and recessed welds
• 5/8-11 threaded arbor hole fits standard angle grinder and die grinder spindles
• 13,195 max RPM rating supports high-speed grinder use within rated limits

Compatibility

Designed as a direct-mount abrasive cone for angle grinders and die grinders fitted with a 5/8-11 threaded spindle. Confirm spindle thread size and tool RPM rating before mounting.

Installation Notes

Mounting and operation of abrasive cones should be performed by trained personnel following ANSI B7.1 safety standards. Disconnect and lock out all power to the grinder before mounting or removing the cone. Never exceed the 13,195 RPM maximum speed rating marked on the product. Inspect the abrasive cone for cracks or damage before each use and discard any cone that shows signs of deterioration.
