With an inside diameter of 0.377 inches, a body outside diameter of 0.75 inches, and an overall length of 0.5 inches, this bushing provides consistent tool guidance in jig plates and fixture setups. Constructed from steel, it delivers the hardness and wear resistance required for repeated drilling cycles. The headless design allows the bushing to sit flush within the jig plate without protruding above the surface, making it suitable for close-tolerance tooling layouts.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in drill jig fixtures across machine shops, production tooling environments, and precision metalworking operations. It is installed directly into a prepared hole in a jig plate using a press fit, eliminating the need for additional fasteners. The P series industry code identifies the bushing size and fit classification for straightforward cross-referencing with standard tooling catalogs. Machinists, toolmakers, and fixture builders install this type of bushing during jig assembly or tooling maintenance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation seats the bushing securely in the jig plate without fasteners\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows flush mounting below the jig plate surface\u003c\/li\u003e\n  \u003cli\u003e0.377 inches inside diameter corresponds to letter size V drill and P series industry code\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides hardness and wear resistance for repeated tool use\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eCompact 0.5 inch overall length suits thin jig plates and tight fixture layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install drill bushing for standard jig and fixture plates requiring a P series press fit headless bushing with a 0.377 inch inside diameter and 0.75 inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into a precision-bored hole in the jig plate. The receiving hole must be bored to the appropriate tolerance to achieve the correct press fit interference. Never drive the bushing in with a hammer directly on the bore face, as this can distort the inside diameter. Inspect the bushing seat after installation to confirm the bushing is fully seated and square to the plate surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.377 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter Size)\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\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\u003eCounterbored\u003c\/strong\u003e: No\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: P488JR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51736841978162,"sku":"P488JR","price":16.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7eec5202809454ae7a64a9a2c2d2d397.jpg?v=1788780960","url":"https:\/\/voomisupply.com\/products\/boneham-p488jr-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
