Built to ANSI standards and hardened to 60 to 65 HRC, this bushing delivers repeatable hole location accuracy in production drilling, reaming, and similar machining operations. The 0.625 inch inside diameter accepts standard tooling, while the 1 inch body outside diameter seats securely in a liner bushing. Inside diameter tolerance is held to a tight +0.0001 to +0.0005 inches, making it suitable for close-tolerance work. The head style allows positive positioning against the jig plate surface.\u003c\/p\u003e\n\u003cp\u003eThis bushing is intended for use in drill jigs and tooling fixtures in industrial, manufacturing, and maintenance machining environments. The slip-fixed design allows the bushing to be installed into a permanent liner bushing and locked in place with an LS-2 compatible lock screw, preventing rotation during cutting operations. It is a renewable bushing, meaning it can be replaced without disturbing the liner or jig plate when wear occurs, reducing fixture maintenance time and cost.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHardened steel construction, 60 to 65 HRC for extended wear life in high-cycle drilling applications\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSlip-fixed (SF) installation method locks into a liner bushing with an LS-2 compatible lock screw\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows in-place replacement without removing the liner bushing\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 1-27\/64 inches seats flush against the jig plate for positive location\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing geometry and dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard slip-fixed drill bushing for use with LS-2 compatible lock screws and standard liner bushings in drill jig and tooling fixture applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by tooling and fixture technicians or machinists. The mating liner bushing must be properly installed and secured in the jig plate before fitting this slip-fixed bushing. Insert the SF6412MH into the liner bushing and secure with an LS-2 lock screw to prevent rotation under cutting load. Ensure the jig and workpiece are fully clamped before initiating any drilling or reaming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-27\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Slip-Fixed (SF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: BONEHAM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SF6412MH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51732495368498,"sku":"SF6412MH","price":25.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_5c8eafec-b6a8-4d8a-9e2f-6b3263e8d405.jpg?v=1788743576","url":"https:\/\/voomisupply.com\/products\/boneham-sf6412mh-slip-fixed-drill-bushing-0-625-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
