At 320 grit, it falls in the extra fine category, making it appropriate for final-pass work where surface finish matters. The stone measures 4 inches in overall length, 0.25 inches wide, and 0.0625 inches thick, giving it a slim profile suited to tight grooves, slots, and precision surfaces. It is not oil filled. Machinists, tool and die workers, and maintenance technicians are the primary users of this type of stone.\u003c\/p\u003e\u003cp\u003eThis polishing stone is used in applications requiring controlled material removal at a fine level, including cleaning up burrs on machined parts, refining valve seats, smoothing keyways, and finishing close-tolerance fits. Its narrow rectangular profile allows access to features that larger stones cannot reach. The extra fine 320 grit designation makes it appropriate for work where surface integrity and dimensional accuracy must be preserved. Sold in a package quantity of 12, it is a practical bench stock item for shops and field kits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320 grit aluminum oxide abrasive for extra fine finishing and deburring\u003c\/li\u003e\n\u003cli\u003eSlim 0.0625 inch thickness allows access to narrow slots and tight features\u003c\/li\u003e\n\u003cli\u003e4 inch overall length provides adequate leverage for hand honing passes\u003c\/li\u003e\n\u003cli\u003eNot oil filled, compatible with dry use or user-applied honing fluid\u003c\/li\u003e\n\u003cli\u003eRectangle profile for consistent contact on flat and grooved surfaces\u003c\/li\u003e\n\u003cli\u003eSold in a package of 12 for bench stock and field kit replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose hand honing and finishing stone suitable for use on metal, plastic, and composite workpieces wherever an extra fine aluminum oxide abrasive is appropriate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis stone is a hand-held abrasive tool and does not require mechanical installation. Secure the workpiece firmly before applying the stone to avoid inconsistent contact or surface damage. If used with honing oil or fluid, apply sparingly and keep the work area clear of slip hazards.
