Norton 66623340042 Quick-change Disc 0.75in Ts Type Ii

Product Description

The NORTON 66623340042 is a 0.75-inch diameter quick-change abrasive disc from the Bear-Tex Rapid Prep series, designed for surface preparation and finishing work on metal and composite materials. It features aluminum oxide abrasive grain bonded to a flexible polyester and nylon web backing, rated to 25,000 RPM for safe use on die grinders and handheld disc sanders. The very fine 150-grit construction removes material at a moderate rate while producing smear-free finishes, making it suitable for blending, deburring, and light surface conditioning. Clean Bond resin technology keeps the grain adhered longer and resists loading for consistent cut performance across the disc life.

This disc is intended for use in fabrication, maintenance, and finishing environments where controlled material removal on ferrous and non-ferrous metals is required. It is well suited for work on stainless steel, brass, bronze, copper, cast iron, hard and soft carbon steels, ductile iron, gray iron, tool steels, super alloys, titanium, and fiberglass or composite materials. Typical install scenarios include weld blending, pre-paint prep, and oxide or scale removal in shop or field settings. The TS Type II quick-change mounting system allows fast disc swaps on compatible die grinders without additional hardware.

Key Features

• Aluminum oxide abrasive grain delivers a higher cut rate and consistent material removal at 150 grit
• High-loft nylon fiber construction extends disc service life compared to standard non-woven constructions
• Clean Bond resin technology prevents smearing and loading for cleaner finishes on sensitive alloys
• Flexible polyester and nylon web backing conforms to contoured and irregular surfaces
• TS Type II quick-change attachment (Type S button) for tool-free disc changes on compatible grinders
• 0.75-inch diameter fits compact die grinders for use in tight clearance areas

Compatibility

Compatible with die grinders and handheld disc sanders equipped with a TS Type II (Type S) quick-change mounting system. Rated for use on 300 and 400 Series Stainless, brass, bronze, copper, cast iron, ductile iron, gray iron, hard and soft carbon steels, super alloys, titanium, tool steels, and fiberglass and composite materials.

Installation Notes

Installation is typically performed by machinists, fabricators, or maintenance technicians using a compatible die grinder with a TS Type II quick-change arbor. Before mounting or removing a disc, ensure the tool is powered off, disconnected from its air or power source, and has come to a complete stop. Never exceed the maximum rated RPM marked on the disc. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or unusual wear.
