Merit Abrasives 08834171192 Psa Disc 4 in 60 Grit

Product Description

The MERIT ABRASIVES 08834171192 is a pressure-sensitive adhesive (PSA) abrasive disc designed for grinding, blending, and surface preparation on a variety of substrates. The disc measures 4 inches in diameter and features 60-grit aluminum oxide abrasive, placing it in the medium-grade cutting range for controlled material removal. A flexible cloth backing absorbs vibration and conforms to contoured surfaces, making it suitable for both flat stock and irregular workpieces. The PSA backing allows for quick, tool-free attachment to compatible backup pads. No vacuum holes are included in this disc.

This disc is used in metalworking, fabrication, and general surface preparation applications where consistent abrasion and flexible backing are required. It is well-suited for weld blending, rust removal, and deburring on metal surfaces in shop or field environments. Licensed tradespeople and fabricators in HVAC, plumbing, and electrical trades commonly use PSA discs during rough-in and fabrication work. The 4-inch size fits compact right-angle grinders and die grinders with matching PSA backup pads.
