Each roll measures 1\/2” in diameter\nby 1-1\/2” in length with a 1\/8” pilot hole and features coarse 40 grit—ideal\nfor aggressive stock removal, deburring, and surface preparation. This\nprofessional-grade set includes ten premium rolls and a CR-9 mandrel for\nsecure mounting and smooth operation. At the core of each roll is next-\ngeneration ceramic alumina abrasive grain, which delivers up to twice the\ncutting speed and three times the service life of traditional aluminum oxide\nabrasives. The ceramic grain self-fractures during use to reveal fresh, sharp\ncutting edges for consistent, reliable performance. Backed with heavy-duty\nX-weight cotton cloth, these rolls offer excellent strength, flexibility, and\nresistance to high-speed operation—up to 18,000 RPM. Ceramic grain abrasives\nare especially well-suited for grinding and finishing hard metals. They\nperform exceptionally on stainless steel, titanium alloys, and exotic alloys\nused in demanding industries such as aerospace and manufacturing. These rolls\nalso excel in high stock removal applications, controlled finishing, and other\nchallenging metalworking tasks. Whether you're working with ferrous or non-\nferrous metals, they provide a versatile, long-lasting abrasive solution. The\nspiral, multi-layer design allows new abrasive layers to be exposed as the\nroll wears, extending lifespan and maintaining a consistent cut. An integrated\nanti-friction grinding aid reduces heat buildup, minimizing discoloration or\nsurface damage. Ideal for bores, pipes, corners, and other tight spaces where\nlarger tools can’t reach, the Pro-Graad cartridge roll is a must-have for\nmachinists, fabricators, and welders. With quick self-clamping via the grooved\nconical arbor, this set is built for efficiency, durability, and precision in\neven the most confined grinding applications.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003e[IN THE BOX]: 50 Pack Pro-Graad 1\/2 Diameter x 1-1\/2 Length x 1\/8 Pilot Hole 40 Grit German Ceramic Grain Straight\/Untapered Cartridge Rolls, 1 each CR-9 1\/4\" shank x 3-1\/2\" overall length Mandrel\u003c\/li\u003e\n \u003cli\u003e[PREMIUM CERAMIC PERFORMANCE]: Engineered with next-generation ceramic alumina grain, these cartridge rolls offer 2X the cut rate and 3X the lifespan of traditional aluminum oxide abrasives.
