The chuck accepts ER16-series collets with a clamping capacity range of 0.019 to 0.394 inches, covering a wide variety of end mills, drills, and reamers. A 1-inch straight shank provides direct spindle compatibility with standard tool holders. Total indicator runout (TIR) is rated at 0.0004 inches, delivering the concentricity required for finish milling and precision boring operations. Actuation is performed with a wrench via the standard ER lock nut. This chuck is installed by machinists and CNC setup technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is suited for light to medium-duty cutting applications in both manual and CNC machining setups. The ER16 collet system is widely used in high-speed spindle applications where compact tool projection and secure clamping are priorities. The 7.2-inch shank length provides reach for setups requiring extended tool access. No through-coolant capability is present on this chuck, so flood or mist coolant must be directed externally at the cutting zone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet system with 0.019 to 0.394 inch clamping capacity range\u003c\/li\u003e\n  \u003cli\u003e0.0004 inch TIR for high-concentricity tool holding\u003c\/li\u003e\n  \u003cli\u003e1-inch straight shank diameter for broad spindle compatibility\u003c\/li\u003e\n  \u003cli\u003e7.2-inch shank length for extended reach applications\u003c\/li\u003e\n  \u003cli\u003eWrench-actuated ER lock nut with 0.86-inch collet nut diameter\u003c\/li\u003e\n  \u003cli\u003eNo through-coolant — external coolant application required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation collet chuck compatible with ER16-series collets.

Use the appropriate ER wrench and spanner to torque the lock nut to the collet manufacturer's specification. Inspect the collet bore and chuck taper for chips or damage before seating the collet. Do not exceed the rated collet capacity range, as oversized tooling will damage the collet and chuck body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.019 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.394 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 7.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 0.86 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Diameter\u003c\/strong\u003e: 13\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Nut Length\u003c\/strong\u003e: 0.68 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.35 x 1.18 x 1.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC09287756\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721901506866,"sku":"SC09287756","price":98.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cad44bacbcf13d53126c8ad2eae16ac2.jpg?v=1788582829","url":"https:\/\/voomisupply.com\/products\/value-collection-sc09287756-er16-collet-chuck","provider":"Voomi Supply","version":"1.0","type":"link"}
