Built around a diamond abrasive material at 120 grit (Grade M125), this 1-inch diameter disc delivers consistent material removal on hard and demanding surfaces. The polyester backing rated at J-weight provides flexibility for contouring work while maintaining durability under load. A maximum rated speed of 30,000 RPM makes it suitable for high-speed rotary tools common in precision grinding and finishing applications. Installers and technicians working on hard materials benefit from the diamond abrasive composition, which outlasts conventional aluminum oxide or ceramic grains on the hardest substrates.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for precision surface finishing, deburring, and light grinding tasks on hard materials including glass, carbide, ceramics, and hardened metals. The 1-inch form factor targets tight clearances and small work areas where larger discs cannot reach. It is commonly used in metalworking, HVAC component fabrication, and maintenance environments where a quick-change system reduces downtime between disc swaps. The Roloc TR button attachment allows tool-free disc changes on compatible TR-series mandrels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiamond abrasive material for cutting performance on hard and exotic substrates\u003c\/li\u003e\n  \u003cli\u003e120 grit (Grade M125) for medium finishing and controlled material removal\u003c\/li\u003e\n  \u003cli\u003eRoloc TR (Type III) quick-change attachment — tool-free disc swaps\u003c\/li\u003e\n  \u003cli\u003eFlexible J-weight polyester backing conforms to contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eRated to 30,000 RPM for compatibility with high-speed rotary tools\u003c\/li\u003e\n  \u003cli\u003e1-inch diameter designed for tight access and precision work areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Roloc TR (Type III) mandrels and quick-change tool systems that accept TR-style button attachments.
