Tru-maxx TM-DNO5A422R Abrasive Cone Type 18 16 Grit

Product Description

The TRU-MAXX TM-DNO5A422R is a Type 18 abrasive cone designed for aggressive material removal on metal surfaces. It uses a zirconia alumina abrasive at 16 grit for coarse stock removal, making it well suited for weld blending, deburring, and surface conditioning on steel and ferrous metals. The cone accepts a 5/8-11 threaded arbor, the standard mounting thread for angle grinders and die grinders used in fabrication and maintenance work. With a maximum rated speed of 14,515 RPM, it operates safely within the range of most common right-angle grinders. Weighing 1.5 pounds per unit, it is a solid, durable abrasive tool built for repeated use under load.

This abrasive cone is used in industrial, fabrication, and maintenance applications where contoured or recessed surfaces require grinding that a flat wheel cannot reach. Typical uses include pipe weld cleanup, inside corner blending, casting flash removal, and heavy deburring on structural steel components. It is appropriate for shop environments and on-site metalwork where a threaded-arbor grinder is the primary tool. The Type 18 cone shape provides good contact geometry on curved and irregular workpiece surfaces.

Key Features

• Type 18 cone shape for access to contoured, recessed, and irregular surfaces
• Zirconia alumina abrasive for aggressive, fast-cutting performance on ferrous metals
• 16 grit coarse grade for heavy stock removal and weld blending
• 5/8-11 threaded arbor hole fits standard angle grinder and die grinder spindles
• 14,515 RPM maximum rated speed compatible with most right-angle grinders
• Consistent cone geometry supports repeatable, controlled material removal

Compatibility

Designed for use with angle grinders and die grinders fitted with a 5/8-11 threaded spindle. Suitable for grinding ferrous metals including steel and cast iron in fabrication, welding, and general metalworking applications.

Installation Notes

Installation is performed by licensed or qualified tradespeople familiar with abrasive tool safety. Always power down and unplug or lock out the grinder before mounting or removing the cone. Thread the cone fully onto the 5/8-11 spindle and verify it is seated securely before operating. Never exceed the 14,515 RPM maximum rated speed marked on the product, and always use appropriate eye and face protection when operating abrasive tools.
