Norton 78072709011 Quick-change Disc 2in 80 Grit Ceramic

Product Description

The NORTON 78072709011 is a 2-inch quick-change abrasive disc from the BlazeX F970 series, designed for aggressive stock removal and surface conditioning on metal. It uses 100% ceramic alumina grain with a self-lubricating treatment that keeps the cut cooler and faster compared to conventional abrasive materials. The Power-Lock Type R attaching system allows for fast disc changes on compatible handheld disc sanders. With an 80 grit (medium-coarse) rating and a fiber backing rated to 30,000 RPM, this disc is built for demanding metal fabrication tasks including weld blending, deburring, and rapid material removal.

This disc is suited for use on 300 and 400 series stainless steel, aluminum, cast iron, gray iron, hard carbon steels, and tool steels. It is intended for use with handheld disc sanders equipped with a Type R quick-change attachment system. The flexible fiber backing conforms slightly to irregular surfaces, making it practical for weld seam blending and edge work in both shop and field environments. Metal fabricators, pipefitters, and maintenance technicians are the primary users of this disc type.

Key Features

• 100% ceramic alumina grain continuously fractures to expose sharper cutting edges throughout disc life
• Self-lubricating grain treatment reduces heat buildup for faster cut rates on sensitive metals like stainless and aluminum
• Resin bond system maximizes grain retention for extended disc life under heavy load
• Type R Power-Lock attaching system enables tool-free disc changes on compatible sanders
• Flexible fiber backing rated to 30,000 RPM accommodates contoured and irregular workpiece surfaces
• 80 grit provides high stock removal rates suited for weld blending and deburring

Compatibility

Designed for use with handheld disc sanders equipped with a Type R quick-change (Power-Lock) attachment system. Compatible materials include 300 series stainless, 400 series stainless, aluminum, cast iron, gray iron, hard carbon steels, and tool steels.

Installation Notes

Installation and disc changes should be performed with the sander powered off and disconnected from its power source. Verify the sander spindle uses the Type R quick-change interface before mounting. Do not exceed the 30,000 RPM maximum disc speed rating. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or visible wear through the abrasive layer.
