It accepts a 20.5 mm inside diameter bore and features a 30 mm body outside diameter with a 25 mm length under the head. This style of renewable bushing is press-fitted into a liner bushing, then locked in place during drilling operations. It is used in jig and fixture setups to guide drill bits, reamers, and other cutting tools with precision. Machinists, tool-and-die makers, and production fixture builders install this type of component in drill jigs for repetitive-hole operations requiring consistent location accuracy.\u003c\/p\u003e\u003cp\u003eSlip-fixed bushings in the SFM series are suited for applications where the bushing must be removed and replaced between operations without disturbing the liner bushing installed in the jig plate. The renewable design allows the same fixture to accept multiple bushing sizes, making it practical for production environments where tooling changes are frequent. This bushing is appropriate for both light and moderate drilling loads in metal fabrication and machining fixtures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSFM slip-fixed design locks into a liner bushing during use and releases for tool changes\u003c\/li\u003e\n\u003cli\u003eRenewable construction allows replacement without reworking the jig plate\u003c\/li\u003e\n\u003cli\u003e20.5 mm inside diameter guides drill or reamer shanks with close tolerance\u003c\/li\u003e\n\u003cli\u003e30 mm body outside diameter provides stable seating in the liner\u003c\/li\u003e\n\u003cli\u003e25 mm length under head suits standard jig plate thicknesses\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 31171603 for procurement classification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for SFM-series liner bushing installations in standard drill jig fixtures requiring a 30 mm body outside diameter slip-fixed bushing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bushing is installed by a machinist or tooling technician into a compatible SFM liner bushing already seated in the jig plate. Ensure the liner bushing bore and the fixture plate are clean and free of chips before insertion. The slip-fixed design requires proper alignment of the locking notch with the lock screw or clamp on the liner bushing. De-energize all machine motion and secure the workpiece before seating or removing the bushing during a tool change.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Slip-Fixed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Code\u003c\/strong\u003e: SFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 20.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.62 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: AM00000879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51737120276786,"sku":"AM00000879","price":44.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2e1344ce9e1f008249550324bac0f19.jpg?v=1788784530","url":"https:\/\/voomisupply.com\/products\/boneham-am00000879-slip-fixed-drill-bushing-sfm","provider":"Voomi Supply","version":"1.0","type":"link"}
