Manufactured from steel and hardened to 60 to 65 HRC, it provides a wear-resistant guide surface for drill bits and other cutting tools. The bushing features a 33\/64 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, a 3\/4 inch body outside diameter, and a 3\/4 inch length under the head. The SF industry code designates this as a slip-fixed style, meaning it installs into a liner bushing and locks in place with a compatible lock screw. It is renewable and compatible with the LS-1 lock screw. Machinists and tool-and-die professionals install this type of bushing in drill jig assemblies.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs, fixtures, and precision tooling setups found in manufacturing, fabrication, and machine shop environments. The slip-fixed design allows the bushing to be removed and replaced without disturbing the jig plate, making it well suited for production runs where different operations require bushing changes. The head style provides a positive seating surface against the jig plate. ANSI standards govern its dimensional specifications, ensuring interchangeability with other ANSI-conforming components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed SF-style bushing meets ANSI dimensional standards for interchangeability\u003c\/li\u003e\n  \u003cli\u003e33\/64 inch inside diameter with precision tolerance of +0.0001 to +0.0005 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for long service life in production tooling\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows replacement without removing the liner or jig plate\u003c\/li\u003e\n  \u003cli\u003eCompatible with LS-1 lock screw for secure seating in the liner bushing\u003c\/li\u003e\n  \u003cli\u003eHead type with 1-3\/64 inch head outside diameter and 1\/4 inch head height for positive plate contact\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ANSI-standard liner bushings and LS-1 compatible lock screws in drill jig and fixture assemblies.

The slip-fixed bushing is pressed or slipped into a mating liner bushing already installed in the jig plate and secured with an LS-1 lock screw. Ensure the machine is de-energized and all moving parts are at rest before servicing the jig assembly. Inspect the liner bushing bore and mating surfaces for wear or damage prior to installing a replacement bushing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\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: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-3\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inches\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\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-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Slip-Fixed\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: SF4812LP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51753275687218,"sku":"SF4812LP","price":21.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_ded4add0-b304-4ad1-a2a5-68f68871e246.jpg?v=1788934868","url":"https:\/\/voomisupply.com\/products\/boneham-sf4812lp-slip-fixed-drill-bushing-33-64-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
