Norton 662529-17880 Type 27 Grinding Wheel 7x1/4x7/8

Product Description

The NORTON 662529-17880 is a Type 27 depressed center grinding wheel engineered for aggressive metal grinding applications. Built under the NorZon Plus product line, this wheel measures 7 inches in diameter, 1/4 inch thick, and accepts a 7/8-inch arbor bore. It is rated to a maximum of 8600 RPM, making it compatible with standard 7-inch angle grinders used daily in fabrication, construction, and maintenance trades. Licensed tradespeople and skilled technicians reach for this wheel when removing weld spatter, grinding down welds, or preparing metal surfaces for further finishing work.

This grinding wheel is suited for use on ferrous metals including steel and iron. Its depressed center Type 27 profile allows the operator to work at a low grinding angle, keeping the wheel face and disc edge in controlled contact with the workpiece. It is a common consumable in structural steel fabrication shops, pipefitting, general ironwork, and on-site metal preparation tasks where a reliable, consistent cut rate is required across repeated passes.
