The set covers a capacity range from 4.00 mm to 10.00 mm in 0.50 mm increments, providing a complete working range for typical ER16 applications. Each collet in the set is rated at a Total Indicator Runout (TIR) of 0.02 mm, supporting accurate concentricity for precision cutting tool retention. The collets are designed with an ER coolant-through system, making them suitable for applications requiring through-spindle coolant delivery. This set is installed by machinists and CNC setup technicians.\u003c\/p\u003e\n\u003cp\u003eThis collet set is suited for machine shops, tool rooms, and production environments where a full range of ER16 collet sizes is needed in a single purchase. The 0.50 mm step increments from 4.00 mm through 10.00 mm allow the set to accommodate a wide variety of shank diameters for end mills, drills, reamers, and other round-shank cutting tools. The coolant-through design supports operations where chip evacuation and tool cooling are priorities, such as deep-hole drilling and high-feed milling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e13-piece set covers 4.00 mm to 10.00 mm in 0.50 mm increments\u003c\/li\u003e\n  \u003cli\u003eER16 series collets compatible with standard ER16 toolholders\u003c\/li\u003e\n  \u003cli\u003e0.02 mm TIR rating supports precision tool concentricity\u003c\/li\u003e\n  \u003cli\u003eCoolant-through (ER Coolant) system design for through-spindle coolant applications\u003c\/li\u003e\n  \u003cli\u003eSingle-set solution eliminates the need to source individual collet sizes separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER16-series toolholders and collet chucks that accept the standard ER16 collet form factor.

Always de-energize and lock out the machine spindle before changing collets. Seat the collet fully into the collet nut before inserting the assembly into the toolholder, and verify runout with a test indicator after clamping to confirm TIR is within tolerance for the application.\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 System\u003c\/strong\u003e: ER Coolant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize Range (mm)\u003c\/strong\u003e: 4.00, 4.50, 5.00, 5.50, 6.00, 6.50, 7.00, 7.50, 8.00, 8.50, 9.00, 9.50, 10.00\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.02 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 784865\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746845262130,"sku":"784865","price":665.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ef0880745b5be6a4a999a191d581582.jpg?v=1788873987","url":"https:\/\/voomisupply.com\/products\/accupro-784865-er16-collet-set-13-piece-4-10mm","provider":"Voomi Supply","version":"1.0","type":"link"}
