With a 5\/16-inch (0.3125-inch) inside diameter and a 1-inch (1.0000-inch) outside diameter, it provides accurate tool guidance during drilling, reaming, and boring operations. The slotted body measures 2-3\/4 inches under the head, with a 2-3\/8-inch slot length that allows chips and coolant to clear during operation. The head thickness is 3\/16 inch (0.1875 inch). This type of bushing is a standard consumable in machine shops, tool rooms, and production environments where repeatable hole location is required.\u003c\/p\u003e\u003cp\u003eType C tool holder bushings are used in fixture-based machining setups across light manufacturing, job shops, and production lines. The slotted design suits applications where chip clearance is a priority, such as deep-hole drilling or through-coolant operations. This bushing fits into standard jig bushing liners that accept a 1-inch outside diameter Type C configuration. Machinists, toolmakers, and fixture builders select this size for smallbore work requiring 5\/16-inch tool guidance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType C slotted bushing design allows chip and coolant clearance during operation\u003c\/li\u003e\n\u003cli\u003e5\/16-inch inside diameter (0.3125 inch) for precise small-bore tool guidance\u003c\/li\u003e\n\u003cli\u003e1-inch outside diameter (1.0000 inch) fits standard Type C liner configurations\u003c\/li\u003e\n\u003cli\u003e2-3\/4-inch length under head provides extended tool support in deep fixture applications\u003c\/li\u003e\n\u003cli\u003e2-3\/8-inch slot length for maximum chip relief along the working body\u003c\/li\u003e\n\u003cli\u003e3\/16-inch head thickness for low-profile seating in fixture plates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for standard Type C rotary tool holder bushing applications requiring a 1-inch outside diameter and 5\/16-inch inside diameter in drill jig and fixture setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by toolmakers or machinists during fixture assembly or bushing replacement. Ensure the mating liner is clean and free of burrs before pressing or inserting the bushing. De-energize and lock out any machine before servicing tooling or replacing bushings in an active fixture. Do not force the bushing if resistance is encountered  -  verify liner inside diameter and bushing outside diameter tolerances before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-3\/4 inches (2.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlot Length\u003c\/strong\u003e: 2-3\/8 inches (2.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COLLIS TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 85511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67915209113906,"sku":"85511","price":115.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3732d94284f7f2b36abd47de719a44bf.jpg?v=1791252697","url":"https:\/\/voomisupply.com\/products\/collis-tool-85511-type-c-tool-holder-bushing-5-16-id-1-od","provider":"Voomi Supply","version":"1.0","type":"link"}
