Classified under industry code PM, this bushing features a 7.9 mm inside diameter and is machined from steel hardened to 60 to 65 HRC, delivering the wear resistance required for repetitive drilling cycles. With a body outside diameter of 12.00 mm and an overall length of 20.00 mm, it is sized for standard jig plate installations. The inside diameter tolerance is held to +0.005\/+0.014 mm, ensuring consistent drill alignment. It is not renewable and not counterbored.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for drill jig fixtures used in production machining environments where repeatable hole location is critical. It installs directly into the jig plate using a press fit, eliminating the need for a liner bushing. Typical applications include production runs on ferrous and non-ferrous workpieces where positional accuracy and bushing rigidity are priorities. Machinists, toolmakers, and fixture builders working in job shops or manufacturing facilities are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation  -  no liner bushing required\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.005\/+0.014 mm for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003eANSI-standard dimensions for compatibility with standard jig plate layouts\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with or below the jig plate surface\u003c\/li\u003e\n  \u003cli\u003eNot counterbored  -  straight through-bore geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-build component for standard ANSI drill jig fixtures requiring a PM-code press fit headless bushing with a 7.9 mm inside 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 the jig plate bore. The jig plate bore must be machined to the appropriate interference fit tolerance before pressing. Never drive the bushing in with a hammer directly on the bushing face, as this can damage the bore geometry. Verify drill clearance and bushing seating depth before committing to production use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7.9 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.005\/+0.014 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Material\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\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 pounds\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: AM00000687\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51743979536690,"sku":"AM00000687","price":19.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_5060eca1-b1d3-4e9b-a0c9-0d219707c969.jpg?v=1788852298","url":"https:\/\/voomisupply.com\/products\/boneham-am00000687-press-fit-headless-drill-bushing-pm","provider":"Voomi Supply","version":"1.0","type":"link"}
