It delivers a total indicator runout (TIR) of 0.0002 inches, making it suitable for applications where concentricity and tool holding precision are critical. The collet measures 1.082 inches in overall length and 0.669 inches in overall diameter. Machinists and tool room technicians use this collet to securely grip cutting tools, drills, reamers, and end mills during metal removal operations.\u003c\/p\u003e\n\u003cp\u003eThis collet fits standard ER16 collet chucks and is sized for tooling with a 0.375 inch shank. The minimum collet capacity is 0.336 inches, allowing it to grip slightly undersized shanks within the ER16 clamping range. It is used in both manual and CNC machining environments across job shops, production facilities, and maintenance tool rooms where repeatable tool holding and low runout are required. Each unit is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet series  -  compatible with standard ER16 collet chucks\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch TIR for precise concentricity in close-tolerance machining\u003c\/li\u003e\n  \u003cli\u003e0.375 inch nominal collet size with a minimum capacity of 0.336 inches\u003c\/li\u003e\n  \u003cli\u003eCompact 1.082 inch overall length suits tight spindle clearance situations\u003c\/li\u003e\n  \u003cli\u003e0.669 inch overall diameter fits standard ER16 chuck bore dimensions\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.06 pounds  -  does not add significant mass to the spindle assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or spare for use in ER16-standard collet chucks requiring a 0.375 inch collet size.

Before inserting or removing a collet, ensure the machine spindle is fully stopped and locked out per machine-specific lockout\/tagout procedures. Seat the collet into the collet nut before threading the assembly into the chuck to avoid damaging the collet taper. Inspect the collet bore and chuck taper for chips or contamination prior to assembly, as debris will directly affect TIR performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.336 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.082 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.669 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Service Code\u003c\/strong\u003e: 5136\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: PARLEC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5UMER16-0375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52002552938802,"sku":"5UMER16-0375","price":76.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95dc5636b43d808ced0f957ae7a05d75.jpg?v=1789998131","url":"https:\/\/voomisupply.com\/products\/parlec-5umer16-0375-er16-collet-0-375-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
