This collet accepts an 8 mm (0.3150 inch) tool shank and delivers a total indicator runout (TIR) of 0.003 mm (0.000118 inch), making it suitable for close-tolerance work where concentricity directly affects surface finish and tool life. The overall length is 40 mm and the overall diameter is 33 mm. No through-coolant is provided. Machinists and toolroom technicians install this collet as part of a standard ER32 toolholding setup.\u003c\/p\u003e\u003cp\u003eThis collet is suited for production and job-shop environments running milling, drilling, reaming, and tapping operations. It fits any machine spindle or toolholder configured for the ER32 collet series. The 8 mm bore accommodates end mills, drills, reamers, and taps with 8 mm shanks. The HP32 designation indicates a high-precision ground collet appropriate for applications where runout control is critical to dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 series collet, HP32 high-precision designation\u003c\/li\u003e\n\u003cli\u003e8 mm bore (0.3150 inch) for standard metric shank tooling\u003c\/li\u003e\n\u003cli\u003e0.003 mm (0.000118 inch) TIR for tight concentricity control\u003c\/li\u003e\n\u003cli\u003e40 mm overall length, 33 mm overall diameter\u003c\/li\u003e\n\u003cli\u003eNo through-coolant — suited for dry or flood coolant setups where internal coolant is not required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with any ER32-standard collet chuck or toolholder.

Power down and lock out the machine spindle before seating or removing the collet. Use a calibrated torque wrench and the manufacturer-specified ER32 collet nut when tightening — do not use standard wrenches that can over- or under-torque the nut. Inspect the collet bore and chuck taper for chips or contamination before assembly, as debris directly degrades runout performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER32 \/ HP32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Bore Size\u003c\/strong\u003e: 8 mm (0.3150 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.003 mm (0.000118 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 33 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02828372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557398675762,"sku":"02828372","price":136.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c5ccde4951ef4e0cd43af93ae217496.jpg?v=1786387278","url":"https:\/\/voomisupply.com\/products\/seco-02828372-er32-collet-8mm-hp32-series","provider":"Voomi Supply","version":"1.0","type":"link"}
