It delivers a 2.76-inch projection from gauge line to collet nose, with an overall length of 5.44 inches. The chuck accepts collets with a minimum capacity of 1\/16 inch and a maximum capacity of 13\/32 inch, covering a broad range of small-diameter cutting tools. Machinists and CNC setup technicians install this chuck on CAT40-spindle machining centers where compact, precise ER16 toolholding is required for drilling, reaming, tapping, and light milling operations.\u003c\/p\u003e\u003cp\u003eThis collet chuck is suited for CNC vertical and horizontal machining centers equipped with CAT40 spindle interfaces. The ER16 collet series is a widely adopted standard, making this chuck a practical choice for production shops running small-diameter tooling in tight-tolerance applications. The 2.76-inch projection provides clearance in workholding setups where tool reach is a factor. It is appropriate for both production and job-shop environments where consistent runout and secure tool retention are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for direct mounting to CAT40-spindle machining centers\u003c\/li\u003e\n\u003cli\u003eER16 collet series compatibility covering 1\/16 inch to 13\/32 inch tool shank diameters\u003c\/li\u003e\n\u003cli\u003e2.76-inch projection suitable for applications requiring extended tool reach\u003c\/li\u003e\n\u003cli\u003e5.44-inch overall length for predictable tool-length offset entry\u003c\/li\u003e\n\u003cli\u003eMini-ER design supports compact, lightweight toolholding for small-diameter work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER16 collets on CAT40-spindle CNC machining centers.

Power down and lock out the machine spindle before mounting or removing the chuck. Use a calibrated torque wrench and the appropriate CAT40 retention knob or drawbar for your specific machine spindle to secure the taper shank. Verify tool runout with a dial indicator after seating the collet and before returning the spindle to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: Mini-ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.76 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 13\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112808\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TECHNIKS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 22356\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51991386849586,"sku":"22356","price":232.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47fc550340c83f784ef8ebcca8c851dd.jpg?v=1789989646","url":"https:\/\/voomisupply.com\/products\/techniks-22356-mini-er-collet-chuck-cat40-er16","provider":"Voomi Supply","version":"1.0","type":"link"}
