Norton 66253022712 Cut-off Wheel 8 in Steel

Product Description

The NORTON 66253022712 is an aluminum oxide reinforced cut-off wheel designed for aggressive cutting of steel and stainless steel. Built to Type 1 (flat) geometry, this wheel measures 8 inches in diameter, 1/8 inches thick, and features a 5/8-inch arbor hole for secure mounting on compatible circular saws and angle grinders. With a 36-grit rating and resinoid bond, it delivers fast, controlled cuts through ferrous and stainless materials. The reinforced construction — sides reinforced with fiberglass mesh — resists shattering under the lateral stresses common in production cutting environments. Licensed tradespeople and fabricators rely on this wheel for both shop and field cutting applications.

This cut-off wheel is intended for use with circular saws rated for abrasive wheel operation. It suits residential and commercial fabrication, metal framing, pipe fitting, and structural steel work. Applications include cutting structural steel, exhaust tubing, pipe, bar stock, and stainless steel sheet. The 36-grit coarseness makes it appropriate for rough parting cuts rather than finish grinding. Maximum operating speed is 7,640 RPM, so operators must verify that their tool's no-load RPM does not exceed this rating before mounting the wheel.

Key Features

• Aluminum oxide abrasive grain, 36 grit — suited for fast parting cuts on steel and stainless steel
• Type 1 (flat) wheel geometry for straight, full-depth cut-off work
• Resinoid bond with sides reinforced for durability under lateral load
• 7,640 RPM maximum speed rating — verify tool compatibility before use
• 5/8-inch arbor hole fits standard circular saw and angle grinder spindles
• Hardness Code T and Grain Structure 4 per Norton specification 57A364-TB25N

Compatibility

Rated for use with circular saws and angle grinders capable of mounting a Type 1 abrasive cut-off wheel with a 5/8-inch arbor. The tool's maximum no-load RPM must not exceed 7,640 RPM. Suitable for cutting steel and stainless steel workpieces.

Installation Notes

Mounting and operation of abrasive cut-off wheels must comply with ANSI B7.1 safety requirements and the tool manufacturer's guard and flange specifications. Power down and disconnect the tool completely before installing or removing the wheel. Never exceed the wheel's 7,640 RPM maximum speed rating, and always use the appropriate flange and arbor nut torqued per the tool manufacturer's specification. Operators should wear appropriate face and eye protection and inspect the wheel for cracks or damage before each use — do not use a damaged wheel.
