Norton 66623340171 Deburring Disc 6in Extra Coarse

Product Description

The NORTON 66623340171 is a rigid deburring disc designed for aggressive material removal on metal workpieces. Built with a dual abrasive construction of aluminum oxide and ceramic, it delivers fast cutting action at an extra coarse grade. The disc measures 6 inches in diameter with a 1/4 inch center arbor hole and a thickness of 1/2 inch. It is rated for a maximum speed of 8000 RPM. This disc is installed on right-angle grinders and bench grinder arbors and is typically used by machinists, fabricators, and metalworking tradespeople who need consistent edge cleanup and surface conditioning on ferrous and non-ferrous materials.

This deburring disc is suited for industrial and shop floor applications where burrs, flash, and sharp edges must be removed from cut, stamped, or machined metal parts. The rigid construction maintains disc geometry under load, making it appropriate for flat surface work and edge deburring on steel, aluminum, and similar substrates. It is sold individually but requires a minimum order quantity of 25 units, making it a practical stock item for production environments and supply rooms.

Installation Notes

Installation should be performed by qualified machinists or metalworking tradespeople familiar with abrasive disc mounting procedures. Always power down and disconnect or lock out the grinder before mounting or removing the disc. Verify that the grinder spindle speed does not exceed the 8000 RPM maximum rating of the disc before operation. Inspect the disc for cracks or damage before each use and never exceed the rated speed.
