It features aluminum oxide abrasive grains resin-bonded to a 5 MIL polyester film backing, delivering consistent, controlled material removal at a 40 micron grade. The backing includes a friction grip coating for slip resistance during operation, keeping the roll stable under load. This product is intended for professional machining and finishing environments where surface geometry and finish tolerances are critical. Machinists and production technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis microfinishing film roll is suited for precision finishing of cylindrical surfaces including automotive camshafts and crankshafts. The 0.472 inch width and 900 foot length make it appropriate for high-volume production or shop environments where consistent abrasive performance across a long run is required. The 1 inch core fits standard film finishing equipment. It is sold by the roll and intended for professional shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive resin-bonded to a 5 MIL polyester film backing for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e40 micron grade for precision microfinishing applications\u003c\/li\u003e\n  \u003cli\u003eFriction grip coating on backing reduces slippage during use\u003c\/li\u003e\n  \u003cli\u003e0.472 inch x 900 ft x 1 inch core dimensions suit standard finishing equipment\u003c\/li\u003e\n  \u003cli\u003eDesigned for cylindrical surface finishing including camshafts and crankshafts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on standard film finishing equipment accepting a 1 inch core.
