Built with vortex agglomerated aluminum oxide grain on a high-loft nylon fiber web backing, it delivers consistent cut and surface quality throughout the disc life. The medium grade (120 grit) construction provides the right balance between material removal and surface finish. The TS (Type II) quick-change attachment system with a silver Type S button allows fast, tool-free disc swaps on compatible handheld disc sanders. At a maximum rating of 40000 RPM, the disc handles demanding production use safely.\u003c\/p\u003e\u003cp\u003eThis disc is suited for professionals working on fabrication, maintenance, and finishing applications across both light and heavy metals. Typical use cases include weld blending, deburring, and surface prep on ferrous and non-ferrous base materials. The flexible nylon web backing conforms to contoured surfaces, making it useful on pipe, tubing, and irregular weld joints where rigid abrasives lose contact. It is used by metalworkers, fabricators, pipefitters, and maintenance technicians in shop and field environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVortex agglomerated aluminum oxide grain for consistent cut rate throughout disc life\u003c\/li\u003e\n\u003cli\u003eHigh-loft nylon fiber web construction conforms to irregular and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eProprietary Clean Bond resin technology for durability and grain retention\u003c\/li\u003e\n\u003cli\u003eTS (Type II) Type S quick-change button for fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eMedium grade, 120 grit — suited for weld blending and finishing soft metals\u003c\/li\u003e\n\u003cli\u003eFlexible backing reduces gouging on curved or contoured workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with handheld disc sanders using a TS (Type II) Type S quick-change attachment system.
