Built on a flexible nylon web backing, it uses vortex agglomerated aluminum oxide grain bonded with proprietary Clean Bond resin technology. The very fine 500-grit rating and non-woven construction allow the disc to conform to contoured surfaces without loading or gouging. Rated to 40000 RPM, it attaches via a Type R attaching system and is compatible with TR Type III quick-change tooling. Licensed trades using die grinders or handheld disc sanders will find this disc well suited to deburring, blending, and final-pass finishing work.\u003c\/p\u003e\u003cp\u003eThis disc is used in metal fabrication, maintenance, and repair applications across residential and commercial settings. It is appropriate for weld blending, surface conditioning, and pre-finishing operations on a wide range of materials. Compatible machine types include die grinders and handheld disc sanders. The flexible nylon web backing makes it effective on flat and contoured workpieces where conformability matters. It is sold individually and used as a consumable in both shop and field service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVortex agglomerated aluminum oxide grain for consistent cut and long service life\u003c\/li\u003e\n\u003cli\u003eHigh-loft nylon web backing provides flexibility and conformability on curved surfaces\u003c\/li\u003e\n\u003cli\u003eProprietary Clean Bond resin technology resists loading on soft and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eVery fine 500 grit rating suited for weld blending and finishing passes\u003c\/li\u003e\n\u003cli\u003eTR Type III quick-change compatibility with Type R attaching system for fast disc swaps\u003c\/li\u003e\n\u003cli\u003eRated to 40000 RPM for use with standard die grinders and handheld disc sanders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with die grinders and handheld disc sanders equipped with TR Type III quick-change systems using a Type R attaching system.
