3M 7000118346 Utility Cloth Roll 240 Grit J-weight

Product Description

The 3M 7000118346 is an aluminum oxide utility cloth roll built on a J-weight backing for light, flexible performance across a wide range of surface preparation tasks. The J-weight cloth construction keeps the roll pliable, allowing it to conform to contours and curved surfaces without cracking or stiffening. At 240 grit, it delivers fine finishing passes that remove minor scratches, scuff surfaces before coating, or blend welds and seams. Weighing 1.34 pounds per roll, it is sized at 1 inch wide by 50 yards long, giving technicians extended run time before a changeover is needed.

This utility cloth roll is suited for metal fabrication shops, HVAC duct work preparation, plumbing fitting cleanup, and general mechanical surface conditioning. The narrow 1-inch width makes it practical for wrapping around pipes, tubing, rods, and small-diameter fittings where sheet abrasives are awkward to control. It is commonly used by HVAC technicians, plumbers, pipefitters, and sheet metal workers who need a reliable abrasive for light deburring, rust removal, and pre-solder or pre-braze surface prep.

Key Features

• Aluminum oxide abrasive mineral for consistent cut and durability on metal surfaces
• J-weight cloth backing is lightweight and flexible, conforming to curved and contoured workpieces
• 240 grit provides fine finishing suitable for pre-coat scuffing, seam blending, and light deburring
• 1-inch width by 50-yard length delivers extended use before roll replacement
• Roll format allows the technician to tear or cut custom lengths on the job

Compatibility

Designed as a general-purpose abrasive cloth roll for hand use and tool wrapping applications across metal, wood, and composite surfaces in trade and light industrial environments.

Installation Notes

This abrasive roll requires no mounting hardware for hand use — tear or cut the desired length and wrap around the workpiece or a backing block. When used on copper pipe or fittings prior to soldering, ensure all abrasive grit residue is wiped clean before applying flux. For power-tool or fixture-driven applications, confirm the tool is rated for the roll width and that the work area is clear of flammable materials before operating.
