3M 7100133700 Scotch-brite Exl Pro Unitized Wheel 3 in

Product Description

The 3M 7100133700 Scotch-Brite EXL PRO EX-UW is a unitized nonwoven abrasive wheel built for laser braze finishing on silicon bronze and similarly demanding surface-conditioning tasks. Its open web, layered construction minimizes heat buildup and resists loading, allowing the wheel to deliver a clean, smooth edge without smearing the workpiece. At 3 inches in diameter and weighing 2.266 pounds per unit, it is suited for bench grinders and right-angle tool setups where consistent, repeatable surface quality is required. Licensed tradespeople and skilled fabricators who work with heat-sensitive base metals will find this wheel a reliable production-floor choice.

This wheel is designed primarily for laser braze finishing applications involving silicon bronze, where surface cleanliness and minimal thermal impact on the base material are critical. The unitized construction allows operation in both clockwise and counterclockwise directions, making it adaptable to a range of grinder configurations encountered in fabrication shops and production environments. It is sold individually and rated for a minimum order quantity of 40 units, reflecting its positioning as a production consumable rather than a one-off shop supply.

Key Features

• Open web construction resists loading and extends effective service life on abrasive finishing tasks
• Nonwoven, layered unitized build minimizes heat buildup to protect heat-sensitive materials like silicon bronze
• Resists smearing for cleaner surfaces and reduced prep time between passes
• Bidirectional operation — runs clockwise or counterclockwise without performance loss
• Consistent edge blending suited to laser braze finishing workflows

Compatibility

Designed as an OEM-style unitized abrasive wheel for use in surface conditioning and finishing applications on silicon bronze and comparable nonferrous or heat-sensitive materials.

Installation Notes

This wheel is installed and replaced by fabricators, metalworkers, or maintenance technicians operating bench grinders or right-angle grinding tools. Always power down and de-energize the grinder before mounting or removing the wheel. Verify that the tool spindle speed does not exceed the wheel's rated maximum RPM before operation. Follow all applicable ANSI B11 and OSHA 29 CFR 1910.215 guarding requirements when mounting abrasive wheels.
