Norton 66252843172 Type 1 Cut-off Wheel 4 in Zirconia

Product Description

The NORTON 66252843172 is a Type 1 flat cut-off wheel designed for aggressive cutting on steel and stainless steel using angle grinders. Built with zirconia alumina abrasive and a resinoid bond, it delivers consistent cut rates and longer wheel life compared to standard aluminum oxide wheels. The wheel measures 4 inches in diameter and 1/8 inches thick with a 3/8 inches arbor hole, and is rated to a maximum of 19,100 RPM. Both sides are reinforced for added durability and safe operation under load. This wheel is part of the Bluefire line, suited for metal fabrication, pipefitting, and general trade cutting tasks.

This cut-off wheel is suited for use in residential and commercial metal fabrication environments, maintenance work, and field service applications. It fits standard angle grinders with a 3/8 inches arbor. Primary applications include cutting steel pipe, structural steel, and stainless steel stock. The 46 grit rating provides a balance of cut speed and wheel longevity appropriate for repeated production cuts or single-pass field cuts.
