Carrying the industry code PM, this bushing features an inside diameter of 3.5 inches, a body outside diameter of approximately 0.276 inches (7.00 mm), and an overall length of approximately 0.472 inches (12.00 mm). It is permanently installed into a jig or fixture plate using a press fit method, eliminating the need for a locking collar or head flange. Machinists, tool and die makers, and production drilling operators rely on this type of bushing to maintain accurate hole location and extend the working life of drill jigs.\u003c\/p\u003e\u003cp\u003eThis drill bushing is suited for use in production drilling jigs, fixture plates, and tooling assemblies where a flush, headless profile is required. The headless design keeps the bushing surface flush with the jig plate, making it practical in close-tolerance applications where clearance above the workpiece surface is limited. It is appropriate for both light production and high-volume repetitive drilling operations in metal fabrication and machine shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method for permanent, secure seating in jig plates\u003c\/li\u003e\n\u003cli\u003eHeadless design provides a flush profile with no projecting flange\u003c\/li\u003e\n\u003cli\u003eInside diameter of 3.5 inches guides drill bits accurately for consistent hole location\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in repetitive drilling applications\u003c\/li\u003e\n\u003cli\u003ePM industry bushing code for standard identification and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for drill jigs and fixture plates requiring a PM-coded press fit headless bushing with a 3.5-inch inside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are typically installed by a machinist or tool and die maker using an arbor press or hydraulic press sized for the bushing outside diameter. The receiving bore in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing type is not intended for removal or reuse. Verify inside diameter clearance against the drill bit shank before installation to confirm proper fit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.276 inches (7.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.472 inches (12.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: AM00000529\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51742078042418,"sku":"AM00000529","price":22.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9780cf8283de1c5a66233c542864d6e.jpg?v=1788835249","url":"https:\/\/voomisupply.com\/products\/boneham-am00000529-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
