It carries the industry code SF and features a 0.1285-inch inside diameter (Number 30 wire size) with a body outside diameter of 0.3125 inches (5\/16 inches). The bushing is manufactured from steel and hardened to 60 to 65 HRC for long service life under repeated drilling cycles. It includes a head and is counterbored for secure seating. A length under head of 0.75 inches (3\/4 inches) provides adequate tool engagement depth for typical jig plate thicknesses. Licensed machinists, toolmakers, and fixture builders install this component in production and prototype drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs and tooling fixtures in manufacturing, metalworking, and machining environments. Its renewable design allows it to be replaced without retiring the fixture, reducing tooling costs in high-cycle production settings. The slip-fixed style allows the bushing to be removed and replaced while remaining locked in position during drilling via a compatible lock screw. It is compatible with the LS-1 lock screw standard, making it interchangeable within LS-1-equipped fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInside diameter of 0.1285 inches (Number 30 wire size) with a tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eBody outside diameter of 0.3125 inches (5\/16 inches) and head outside diameter of 35\/64 inches\u003c\/li\u003e\n  \u003cli\u003eLength under head of 3\/4 inches for adequate engagement in standard jig plate thicknesses\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear resistance in repetitive drilling applications\u003c\/li\u003e\n  \u003cli\u003eCounterbored and head-style design with LS-1 lock screw compatibility for secure, removable installation\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design allows field replacement without replacing the fixture liner\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with LS-1 lock screws.

Ensure the fixture liner bore is clean and free of chips before pressing or seating the bushing. Always disengage power to the drilling machine before servicing jig components. The LS-1 lock screw must be properly engaged to prevent bushing rotation or pull-out during drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.1285 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Size)\u003c\/strong\u003e: Number 30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 35\/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\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead or Headless\u003c\/strong\u003e: Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: Yes\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\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\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: CB00000012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51729646682418,"sku":"CB00000012","price":19.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_7c42b661-e7cc-4e2f-bbe2-3de1e88b91f4.jpg?v=1788707172","url":"https:\/\/voomisupply.com\/products\/boneham-cb00000012-slip-fixed-drill-bushing-0-1285-id","provider":"Voomi Supply","version":"1.0","type":"link"}
