Norton 66243527955 Cut-off Wheel 4in Aluminum Oxide Type 1

Product Description

The NORTON 66243527955 is a Type 1 (01/41) flat cut-off wheel designed for fast, straight cutting on steel and stainless steel. Built with aluminum oxide abrasive and a resinoid bond, the wheel measures 4 inches in diameter and 3/32 inches thick, with a 5/8-inch arbor hole. Both sides are reinforced for added durability under lateral stress. Rated to 15280 RPM, it is sized for use with standard 4-inch angle grinders. The Gemini Right Cut designation indicates a product engineered for clean, efficient cutting with minimal burr. Tradespeople in fabrication, mechanical, and welding environments rely on this wheel for everyday cut-off work.

This cut-off wheel is suited for residential and commercial trade applications involving mild steel and stainless steel. Typical uses include cutting pipe, rebar, angle iron, tube stock, and structural members. The 4-inch diameter and Type 1 flat profile make it compatible with compact angle grinders commonly carried by plumbers, pipefitters, ironworkers, and HVAC technicians working in tight spaces. The reinforced construction handles the vibration and side loads encountered in field cutting conditions.
