The NORTON 088341-60458 is a Merit Ultra Ceramic Plus Powerlock abrasive disc designed for aggressive material removal in grinding and finishing applications. Featuring a Type 3 configuration and a coarse 36 grit ceramic abrasive, this disc delivers fast cut rates and extended life on metal, stainless steel, and other hard materials. The Powerlock quick-change attachment system allows rapid disc swaps without additional tools. Sold in boxes of 50, this disc is a standard choice for fabricators, welders, and metal finishing technicians who need consistent, high-volume abrasive performance.
This disc is suited for use on right-angle grinders equipped with a Powerlock hub or mandrel. At 3 inches in diameter, it fits compact grinders commonly used in tight spaces, weld seam blending, and surface prep work. The 36 grit rating makes it appropriate for heavy stock removal, deburring, and weld leveling on ferrous and non-ferrous metals. Typical users include metal fabricators, maintenance technicians, and welding professionals working in both shop and field environments.
Designed for use with right-angle grinders equipped with a Powerlock-style hub or compatible quick-change mandrel system accepting 3-inch abrasive discs.
Installation should be performed by a qualified technician familiar with abrasive tooling and grinder safety. Always power down and disconnect the grinder before changing discs. Confirm the grinder spindle speed rating meets or exceeds the maximum RPM rating of the disc before operation. Inspect each disc for damage prior to use and follow applicable ANSI B7.1 safety standards for abrasive wheel mounting and use.
