Norton 66253322158 Cutoff Wheel 13-3/4 in Aluminum Oxide

Product Description

The NORTON 66253322158 is a Type 1 (01/41) flat cutoff wheel designed for straight, on-center cutting of steel in stationary tool applications. It measures 13-3/4 inches in diameter and 0.098 inches thick, with a 1-1/4 inch arbor hole. The wheel is bonded with a resinoid bond and constructed from aluminum oxide abrasive, which delivers consistent stock removal on ferrous metals. At a maximum rated speed of 3,300 RPM, it is sized for stationary cutoff saws and chop saws used in fabrication, maintenance, and metalworking environments. Weighing 1.575 pounds, it is handled and mounted by metal fabricators, maintenance technicians, and shop personnel.

This wheel is suited for stationary cutoff operations on steel stock, structural shapes, pipe, and bar stock in shop or maintenance settings. The Type 1 flat profile is the standard geometry for straight cutting applications where the wheel runs perpendicular to the workpiece. The aluminum oxide abrasive is well matched to carbon steel and general ferrous materials. The non-reinforced resinoid bond construction suits the lower operating speeds characteristic of stationary cutoff machines rather than handheld angle grinders.

Key Features

• 13-3/4 inch diameter suits full-size stationary cutoff saws
• Aluminum oxide abrasive for consistent cutting on steel and ferrous metals
• Resinoid bond provides controlled cut rate and wheel durability
• Type 1 (01/41) flat wheel geometry for straight, on-center cuts
• Non-reinforced construction matched to stationary tool use at 3,300 RPM max
• Meets ML-414 specification

Compatibility

Designed for use with stationary cutoff tools rated for a 13-3/4 inch wheel diameter, 1-1/4 inch arbor, and a maximum operating speed at or above 3,300 RPM. Application is steel and general ferrous materials.

Installation Notes

Mounting and wheel changes must be performed by qualified shop personnel with the machine fully de-energized and the power source locked out before handling the wheel. Verify the machine spindle speed does not exceed the 3,300 RPM maximum wheel rating before operation. Inspect the wheel for cracks or chips before every mount and do not use a damaged wheel. Follow ANSI B7.1 safe use requirements for abrasive wheels when installing and guarding this product.
