With a nominal collet size of 12 mm (0.4720 inches) and a total indicator runout (TIR) of 0.003 mm (0.000118 inches), this collet is built for applications where concentricity and repeatability are critical. The overall length is 40 mm and the overall diameter is 33 mm. Installation is handled by machinists and CNC setup technicians working in precision machining environments.\u003c\/p\u003e\u003cp\u003eThis collet is suited for use in ER32-compatible toolholders found in production machining, tool and die, and general metalworking operations. It accepts 12 mm shank tooling and is appropriate for both roughing and finishing operations where tight runout tolerance is required. The HP32 series designation indicates a higher-precision grade within the ER32 family. Through-coolant is not supported by this collet.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 collet series with HP32 high-precision grade designation\u003c\/li\u003e\n\u003cli\u003e12 mm nominal collet size (0.4720 inches decimal equivalent)\u003c\/li\u003e\n\u003cli\u003e0.003 mm TIR for high concentricity and consistent tool life\u003c\/li\u003e\n\u003cli\u003e40 mm overall length with 33 mm overall diameter\u003c\/li\u003e\n\u003cli\u003eNo through-coolant bore — solid collet body construction\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 27112800, Product Service Code 5136\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ER32-standard collet chucks and toolholders accepting 12 mm shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Before installing or removing a collet, ensure the machine spindle is fully stopped and locked out per standard lockout\/tagout procedures. The collet should be seated fully into the ER32 collet nut before tightening. Use a calibrated torque wrench and an appropriate ER collet nut spanner to achieve proper clamping force without over-tightening, which can distort the collet bore and degrade TIR.\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 Size\u003c\/strong\u003e: 12 mm (0.4720 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.003 mm (0.000118 inches)\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: 0.31 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Service Code\u003c\/strong\u003e: 5136\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: 02828376\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559128924466,"sku":"02828376","price":136.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fba691af4b6df60b1ae6c99d7a5330f6.jpg?v=1786428572","url":"https:\/\/voomisupply.com\/products\/seco-02828376-er32-hp32-collet-12-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
