BC31618 Flexible Cylinder Hone 180G","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe BRUSH RESEARCH MFG. BC31618 is a flexible cylinder hone designed for precision finishing and deburring of small-bore cylindrical surfaces. Built with silicon carbide abrasive at 180 grit, this tool delivers an extra fine finish on bores as small as 0.1875 inches in diameter. The hone operates at up to 1200 RPM and features an overall length of 6 inches with an abrasive length of 0.75 inches. The 0.073-inch shank diameter is compatible with standard drill chucks and flexible shaft tools. Machinists, engine rebuilders, and mechanical technicians use this hone to restore surface finish and geometry in tight bores where rigid tooling cannot reach.\u003c\/p\u003e\n\u003cp\u003eThis hone is suited for use on mild steel, stainless steel, and cast iron workpieces. Typical applications include cylinder bores, valve guides, hydraulic fittings, and other precision small-bore components requiring a controlled surface finish. The flexible ball-style construction allows the abrasive globules to follow the bore contour, making it effective in both through-bores and blind-bore applications. It is commonly used in machine shops, engine rebuild facilities, and industrial maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide abrasive at 180 grit for an extra fine surface finish\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.1875 inches for use in tight, small-bore applications\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 1200 RPM for controlled, safe honing\u003c\/li\u003e\n  \u003cli\u003eAbrasive length of 0.75 inches for targeted bore contact\u003c\/li\u003e\n  \u003cli\u003e0.073-inch shank diameter fits standard drill chucks and rotary tools\u003c\/li\u003e\n  \u003cli\u003eCompatible with mild steel, stainless steel, and cast iron materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on mild steel, stainless steel, and cast iron bore surfaces with a minimum bore diameter of 0.1875 inches and a maximum bore diameter of 0.187 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis hone is installed by inserting the shank into a standard drill chuck or flexible shaft tool. Ensure the workpiece is secured before operation and do not exceed 1200 RPM. A light honing oil or coolant is typically applied during use to flush abrasive debris and extend tool life. Inspect the bore diameter before and after honing to verify dimensions remain within specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 180\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Mild Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.073 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BRUSH RESEARCH MFG.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BC31618\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRUSH RESEARCH MFG","offers":[{"title":"Default Title","offer_id":67911628357938,"sku":"BC31618","price":38.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de2c1a25281030aa725b9fcd141c81fd_22465809-069d-4170-be9c-da7ce357c76b.jpg?v=1791214577","url":"https:\/\/voomisupply.com\/products\/brush-research-mfg-bc31618-flexible-cylinder-hone-180g","provider":"Voomi Supply","version":"1.0","type":"link"}
