Machined from steel and hardened to 60 to 65 HRC, this bushing delivers consistent bore alignment over repeated tool cycles. It features a 21\/64-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, a 1\/2-inch body outside diameter, and a 1-inch length under the head. The head outside diameter measures 51\/64 inches with a 1\/4-inch head height. Installation is handled by tooling and fixture professionals in manufacturing, metalworking, and machining environments.\u003c\/p\u003e\n\u003cp\u003eThis slip-fixed bushing is suited for use in drill jigs where the bushing must be locked in place during the machining operation but can be removed and replaced without scrapping the jig plate. The SF-style configuration, combined with LS-1 lock screw compatibility, makes it a standard choice for production drilling fixtures in both light and medium-duty machining setups. It conforms to ANSI standards, making it directly interchangeable with other ANSI SF-series bushings of the same dimensions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed (SF) installation method locks bushing in place during drilling operations\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches ensures precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eLS-1 compatible lock screw secures the bushing in the jig liner\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows bushing replacement without jig plate replacement\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for direct dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard SF-series slip-fixed renewable drill bushing.

The LS-1 lock screw should be installed and tightened per fixture engineering specifications to prevent rotation during the cutting operation. Always ensure the jig liner bore and mating surfaces are clean and free of burrs before pressing the bushing into position. Follow applicable shop safety and workholding procedures when handling hardened components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Slip-Fixed (SF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 21\/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: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 51\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead or Headless\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\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\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\u003eStandard\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: CB00001148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51747664888114,"sku":"CB00001148","price":19.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_3ec58091-0e82-41cb-ba76-ad85582f1788.jpg?v=1788884241","url":"https:\/\/voomisupply.com\/products\/boneham-cb00001148-slip-fixed-drill-bushing-21-64-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
