Sized at 7\/32 inch (0.2188 inches decimal), it delivers a Total Indicator Runout (TIR) of 0.0002 inches, making it suitable for applications where concentricity and surface finish are critical. The collet features through-coolant capability, allowing cutting fluid to pass directly to the tool tip. Machinists and CNC operators install this collet into compatible ER25 collet chucks or tool holders as part of standard tooling setups.\u003c\/p\u003e\n\u003cp\u003eThis collet is used in production and job-shop machining environments where ER25 tooling systems are standard. It fits residential and commercial machine shop equipment configured with ER25-compatible chucks. The 7\/32 inch bore size accommodates round shank cutting tools of that diameter, including end mills, drills, and reamers. Through-coolant support makes it well suited for deep-hole drilling and high-speed milling where heat management at the cutting edge is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER25 collet series  -  fits standard ER25 chucks and tool holders\u003c\/li\u003e\n  \u003cli\u003e7\/32 inch (0.2188 inches) bore for accurate round-shank tool clamping\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches for high-precision concentricity\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capable  -  directs cutting fluid to the tool tip\u003c\/li\u003e\n  \u003cli\u003eSupports high-speed milling, drilling, and reaming operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER25-compatible collet chucks and tool holders accepting 7\/32 inch round shank tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Clean the collet bore and chuck taper thoroughly before seating the collet to prevent runout caused by debris. Use a calibrated torque wrench with the appropriate ER25 collet nut spanner to achieve proper clamping force without over-torquing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Inch)\u003c\/strong\u003e: 7\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Decimal Inch)\u003c\/strong\u003e: 0.2188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\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: 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: 04225-7\/32\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52016231940402,"sku":"04225-7\/32","price":40.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/765c325cb5330fe65751360e21e0dd77.jpg?v=1790008454","url":"https:\/\/voomisupply.com\/products\/techniks-04225-7-32-er25-collet-7-32-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
