It expands to contact the interior wall of a bore and holds with up to 10,000 pounds of holding force, making it suitable for heavy-duty turning, milling, and grinding applications. The clamp uses a 5\/8-11 center screw to drive expansion and mounts to a fixture plate via three mounting holes on a 4.648-inch mount hole diameter circle with 1\/4-20 mounting screws. Overall height is 1.79 inches. This component is installed and set up by machinists and tooling engineers in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 31450 is used in CNC and manual machining setups where external clamping is impractical or where repeatable, concentric part location is required. It is well suited for chucking rings, flanged parts, sleeves, and any workpiece with a usable internal bore. The expansion diameter range of 1.15 to 4.06 inches covers a wide variety of bore sizes in a single clamp body, reducing the need for multiple dedicated fixtures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExpansion diameter range: 1.15 to 4.06 inches for broad bore coverage\u003c\/li\u003e\n\u003cli\u003e10,000 lb holding force for secure fixturing under heavy cutting loads\u003c\/li\u003e\n\u003cli\u003e224 ft\/lb rated torque capacity\u003c\/li\u003e\n\u003cli\u003e5\/8-11 center screw drives expansion; 1\/4-20 mounting screws secure to fixture plate\u003c\/li\u003e\n\u003cli\u003eMild steel construction for durability in shop environments\u003c\/li\u003e\n\u003cli\u003eThree-hole flange mount pattern on a 4.648-inch bolt circle for stable base attachment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style ID expansion clamp for use with standard fixture plates and tombstones drilled to accept a three-hole mount pattern on a 4.648-inch mount hole diameter circle with 1\/4-20 mounting screws.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or tooling engineer. Before installing or adjusting the clamp, ensure the machine is powered down and the spindle is fully stopped. Mount the flange securely to the fixture plate using all three mounting holes before engaging the center screw to expand the clamp body into the bore. Do not exceed the rated torque when driving the center screw, and verify holding force is adequate for the cutting forces expected before beginning the machining cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Expansion Diameter\u003c\/strong\u003e: 1.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Expansion Diameter\u003c\/strong\u003e: 4.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Force\u003c\/strong\u003e: 10,000 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Rating\u003c\/strong\u003e: 224 ft\/lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Screw Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Screw Thread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 5.232 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Thickness\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Hole Diameter\u003c\/strong\u003e: 4.648 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Mount Holes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpansion Height\u003c\/strong\u003e: 1.27 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight Above Flange\u003c\/strong\u003e: 1.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.79 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length Below Base\u003c\/strong\u003e: 0.79 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Mild Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.52 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITEE-BITE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITEE-BITE","offers":[{"title":"Default Title","offer_id":51720955822386,"sku":"31450","price":253.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/187f6659a3980bd6c7b0f51878037fcb.jpg?v=1788571445","url":"https:\/\/voomisupply.com\/products\/mitee-bite-31450-id-expansion-clamp-mild-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
