Walter Surface Technologies 11T552 Cut-off Wheel 5in 60G

Product Description

The WALTER SURFACE TECHNOLOGIES 11T552 is a Type 1 resinoid-bonded cut-off wheel engineered for aggressive cutting on steel and stainless steel. Measuring 5 inches in diameter and 1/32 inches thick, this wheel is built around a zirconia alumina abrasive grain rated at 60 grit for fast, consistent stock removal. The reinforced construction handles the lateral and rotational stresses generated during cut-off operations, and the 7/8-inch arbor hole fits standard angle grinder spindles. Maximum operating speed is 12,200 RPM. Licensed tradespeople and fabricators in metal fabrication, maintenance, and pipe work are the primary installers and users.

This cut-off wheel is designed for use with angle grinders on steel and stainless steel workpieces. Typical applications include cutting structural steel, pipe, bar stock, and sheet metal in both shop and field environments. The thin 1/32-inch kerf minimizes material loss and heat buildup during the cut. The zirconia alumina abrasive grain specification ZA60 provides a balance of cut rate and wheel life suited to production and maintenance cutting tasks.

Key Features

• Zirconia alumina abrasive grain (spec ZA60) for fast cutting on steel and stainless steel
• Type 1 flat profile with 1/32-inch thickness for minimal kerf and reduced heat
• Reinforced resinoid bond handles high-stress cut-off operations
• 12,200 RPM maximum speed rating
• 7/8-inch arbor hole fits standard angle grinder spindles
• Black wheel color aids visual identification on the job

Compatibility

Designed for use with angle grinders on steel and stainless steel. The 5-inch diameter and 7/8-inch arbor hole are compatible with standard angle grinder configurations that accept Type 1 cut-off wheels at this size.

Installation Notes

Cut-off wheels must be mounted and operated by personnel familiar with angle grinder safety requirements, including ANSI B7.1 and applicable OSHA standards. Always inspect the wheel for cracks or chips before mounting and never exceed the 12,200 RPM maximum rated speed. Wear appropriate PPE including face shield, gloves, and hearing protection during operation. Do not use this wheel for grinding or side-loading; it is rated for straight cut-off work only.
