It carries a 400-grit diamond abrasive on a flexible polyester (J-weight) backing, making it suited for fine finishing and precision surface work on hard materials. The Type R attachment system allows fast disc swaps without additional hardware. Rated to 30,000 RPM, this disc is appropriate for use with compatible high-speed rotary tools and die grinders. The 1-1\/2 inch diameter suits work in tight or contoured areas where a larger disc cannot reach. It ships as a single disc per package.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in applications requiring fine material removal or surface finishing on hard substrates such as carbide, ceramics, hardened steel, glass, and similar materials. The diamond abrasive and fine 400-grit cut make it well-suited for deburring, edge refining, and blending on precision components. It is commonly used by machinists, tool and die technicians, and maintenance professionals working on hard-face or coated surfaces. The flexible backing allows the disc to conform to slight surface variations during finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e400-grit diamond abrasive for fine finishing on hard materials\u003c\/li\u003e\n  \u003cli\u003eRoloc TR (Type R) quick-change attachment for fast, tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eFlexible J-weight polyester backing conforms to contoured surfaces\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch diameter designed for access in tight or restricted areas\u003c\/li\u003e\n  \u003cli\u003eRated to 30,000 RPM for use with compatible high-speed rotary tools\u003c\/li\u003e\n  \u003cli\u003eSingle-disc package quantity for low-volume or trial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Roloc TR (Type R) quick-change tool holders and compatible die grinders or rotary tools that accept the Type R attachment system.
