The set covers a maximum capacity of 3\/4 inches and steps through sizes in 1\/32-inch increments, giving machinists a full working range without gaps. Each collet in the set conforms to the ER32 collet system standard, providing consistent radial runout control and reliable clamping force across the size range. This set is well suited for shops that need a complete ER32 lineup in a single purchase rather than sourcing individual collets.\u003c\/p\u003e\n\u003cp\u003eThis collet set is appropriate for use in both production and job-shop environments where a variety of tool shank diameters must be held securely. Common applications include end mill, drill, reamer, and tap holding in vertical or horizontal machining centers. The 21-piece configuration covers the full practical range of the ER32 system in 1\/32-inch steps up to 3\/4 inches, making it a standard outfitting choice when commissioning a new spindle or replacing a worn set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21-piece set covers the full ER32 size range in 1\/32-inch increments up to 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003eER32 collet system standard for broad compatibility with ER32 toolholders and chucks\u003c\/li\u003e\n  \u003cli\u003eConsistent clamping across all included sizes for reliable tool runout control\u003c\/li\u003e\n  \u003cli\u003eSingle-purchase solution for shops equipping or restocking an ER32 spindle setup\u003c\/li\u003e\n  \u003cli\u003eSized for end mills, drills, reamers, and taps within the 3\/4-inch capacity range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER32-standard collet chucks and toolholders.

The machine spindle must be stopped and all motion fully arrested before changing collets. Inspect each collet bore and seating taper for chips or damage before installation, as debris will affect runout and clamping force. Torque the collet nut per the toolholder manufacturer guidance using a calibrated spanner to avoid under- or over-clamping.\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: ER32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize Increments\u003c\/strong\u003e: 1\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: TECHNIKS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 04212-21(SET)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51998188339506,"sku":"04212-21(SET)","price":830.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce288881135f8e0ac89824f78368cf83.jpg?v=1789994711","url":"https:\/\/voomisupply.com\/products\/techniks-04212-21set-er32-collet-set-21-pc-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
