Walter Surface Technologies 11U303 Cut-off Wheel Type 1

Product Description

The WALTER SURFACE TECHNOLOGIES 11U303 is a Type 1 resinoid-bonded aluminum oxide cut-off wheel designed for precision cutting on aluminum workpieces. Measuring 3 inches in diameter and 1/32 inches thick with a 3/8 inches arbor hole, this reinforced wheel carries an A60 specification with 60 grit and a maximum rated speed of 25,470 RPM. The resinoid bond provides consistent cut performance and controlled wear across repeated cutting passes. It is a single-piece consumable intended for use on angle grinders in fabrication, maintenance, and metalworking applications.

This cut-off wheel is suited for light-duty cutting tasks on aluminum in both shop and field environments. The thin 1/32 inches kerf minimizes material loss and reduces heat buildup during cuts, making it appropriate for finish-sensitive aluminum stock, tubing, and profiles. Typical users include sheet metal fabricators, HVAC installers working with aluminum duct components, pipefitters, and general maintenance technicians who require a dedicated aluminum-cutting wheel for their angle grinder setups.

Key Features

• Type 1 (01/41) flat profile for straight, controlled cut-off work
• 60 grit aluminum oxide abrasive with A60 specification rating
• Reinforced resinoid bond construction for durability and safety at speed
• 1/32 inches thin kerf reduces heat and material loss on aluminum cuts
• Maximum rated speed of 25,470 RPM for compatibility with standard angle grinders
• 3/8 inches arbor hole fits common angle grinder spindle sizes

Compatibility

Designed for use with angle grinders. Optimized for cutting aluminum per the A60 application specification. Verify that the grinder spindle speed does not exceed the 25,470 RPM maximum rating before mounting.

Installation Notes

Mounting and use of abrasive cut-off wheels should be performed by a qualified technician familiar with angle grinder safety practices. Always power down and disconnect the grinder before changing wheels. Inspect the wheel for cracks or chips before each use and confirm the arbor hole fits the spindle without forcing. Follow ANSI B7.1 and tool manufacturer guidelines for proper guard placement and wheel mounting torque.
