Rated Extra Fine at 320 grit, this rectangular hone delivers controlled material removal and a refined surface finish in applications where standard abrasives fall short. The abrasive face measures 3\/8 inches wide by 1\/4 inches high with a 1 inch length of cut and a 4 inch overall length, making it well suited for detail work in confined bores, slots, and channels. Diamond concentration is 100 percent, ensuring consistent cutting action across the full abrasive depth. Machinists, tool and die makers, and precision grinding technicians are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis hone is used in machine shops, tool rooms, and maintenance environments where fine finishing of small bores, valve guides, cylinder ports, mold cavities, or precision fixtures is required. The rectangular hone shape suits flat-bottomed slots and rectangular profiles that round hones cannot reach. Its compact 4 inch overall length allows use in benchtop setups or hand-held honing fixtures. The Extra Fine grit designation makes it appropriate for final-pass finishing rather than aggressive stock removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320 grit Extra Fine diamond abrasive for controlled finish honing\u003c\/li\u003e\n\u003cli\u003e100 percent diamond concentration for consistent, long-lasting cutting performance\u003c\/li\u003e\n\u003cli\u003eRectangle hone shape for flat-bottomed slots, keyways, and non-circular bores\u003c\/li\u003e\n\u003cli\u003e1 inch length of cut with 1\/16 inch abrasive depth for precise engagement\u003c\/li\u003e\n\u003cli\u003e4 inch overall length suits hand-held and fixture-mounted honing applications\u003c\/li\u003e\n\u003cli\u003eSingle end design for direct, focused abrasive contact\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom hone compatible with hand honing fixtures and manual honing applications requiring a rectangular diamond abrasive profile in the Extra Fine grit range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDiamond hones of this type are installed or used by machinists and precision grind technicians in controlled shop environments. Secure the workpiece or fixture before engaging the hone to prevent lateral movement during the stroke. Apply a compatible honing oil or fluid to extend abrasive life and improve surface finish. Avoid side-loading the hone beyond its rated geometry, as this can cause premature abrasive wear or chipping of the diamond matrix.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHone Shape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Depth\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiamond Concentration\u003c\/strong\u003e: 100 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69014192140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538834653490,"sku":"69014192140","price":292.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2d80f3e5747060f53231a9ee8836e24.jpg?v=1785827918","url":"https:\/\/voomisupply.com\/products\/norton-69014192140-diamond-hone-320-grit-extra-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
