Weiler 56281 Type 1 Cutoff Wheel 4.5 in Aluminum Oxide 60 Grit

Product Description

The WEILER 56281 is a Type 1 flat cutoff wheel engineered for fast, clean cuts on steel. Built with aluminum oxide abrasive and a resinoid bond, this wheel delivers consistent cutting action on ferrous metals in demanding shop and field environments. At 0.045 inches thick, the wheel minimizes material loss and reduces heat buildup at the cut. It carries a hardness code of T and meets the A60T specification. Licensed HVAC technicians, pipefitters, electricians, and metal fabricators rely on this style of wheel daily when working with steel conduit, angle iron, pipe, and structural stock.

This wheel is designed for use with standard angle grinders fitted with a 7/8 inch arbor. The 4.5 inch diameter and thin kerf profile make it suitable for tight-clearance cuts in mechanical, electrical, and plumbing rough-in work, as well as general fabrication. Its black resinoid-bonded construction handles the vibration and side loading typical in professional trade applications on steel substrates.

Key Features

• Type 1 flat profile for straight, controlled cutoff cuts on steel
• Aluminum oxide abrasive rated at 60 grit for aggressive stock removal
• 0.045 inch thickness reduces kerf width and material waste
• Resinoid bond with T hardness code for durability under sustained load
• 13,300 maximum RPM rating compatible with standard 4.5 inch angle grinders
• Reinforced construction for safe operation at rated speed

Compatibility

Designed for use with angle grinders accepting a 7/8 inch arbor hole and a 4.5 inch diameter cutoff wheel. Rated for cutting steel per the A60T specification.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following ANSI B7.1 and grinder manufacturer guidelines. Always power down and unplug or de-energize the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never operate above the 13,300 RPM maximum rating. Appropriate PPE including face shield, gloves, and hearing protection is required during operation.
