This head-type bushing features a 33\/64-inch inside diameter, a body outside diameter of 0.750 inches, and a length under head of 3\/8 inches. Manufactured from steel and hardened to 60 to 65 HRC, it provides consistent bore guidance and resists wear under repeated tooling cycles. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures close positional accuracy. Qualified machinists, tool and die makers, and fixture builders install this bushing in production drilling, reaming, and similar operations where repeatable hole location is critical.\u003c\/p\u003e\n\u003cp\u003eThe SFT486LP is suited for use in slip-fixed bushing arrangements where the bushing is locked in place during the tooling operation and removed for tool changes. The head outside diameter measures 1 inch with a head height of 1\/4 inch, seating flush against the jig plate face. A head outside diameter of 1 inch provides a stable bearing surface against the fixture. Lock screw compatibility with the LS-TW-2 fastener secures the bushing in its liner during operation. This configuration is common in production drilling jigs requiring frequent bushing changes between operations without replacing the liner bushing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel construction hardened to 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 delivers close positional accuracy for precision hole guidance\u003c\/li\u003e\n  \u003cli\u003eSlip-fixed installation method allows quick removal and replacement without disturbing the liner bushing\u003c\/li\u003e\n  \u003cli\u003eHead-type design with 1-inch head OD and 1\/4-inch head height seats securely against the jig plate face\u003c\/li\u003e\n  \u003cli\u003eCompatible with LS-TW-2 lock screw for positive retention during the drilling operation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with LS-TW-2 compatible lock screws.

Ensure the liner bushing bore and mating surfaces are clean and free of chips before inserting the bushing. The bushing should be oriented so the lock screw engages the head notch correctly before tightening the LS-TW-2 screw. Do not press or hammer the bushing into the liner, as the slip-fixed design relies on a sliding fit for removal between operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 33\/64 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: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Slip-Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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 Bushing\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-TW-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: SFT486LP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51746258452786,"sku":"SFT486LP","price":20.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_5c199f29-361a-45a3-9e0c-de1975e0e25e.jpg?v=1788867756","url":"https:\/\/voomisupply.com\/products\/boneham-sft486lp-slip-fixed-drill-bushing-33-64-in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
