It secures 3\/8 inch hand taps and applies axial tension during the tapping cycle, helping maintain thread quality and reducing the risk of tap breakage. The ER25 series collet is a widely adopted standard in precision toolholding, and this tension-style variant is specifically suited for rigid and semi-rigid tapping applications. At 0.19 pounds, the collet is lightweight and fits standard ER25 nuts and chucks without modification.\u003c\/p\u003e\n\u003cp\u003eThis collet is used in machine shop environments for hand tap operations on vertical machining centers, knee mills, and dedicated tapping machines. The tension function accommodates slight axial float, which is valuable when the machine's spindle pitch does not perfectly match the tap's lead. It is installed by machinists and CNC operators handling threaded-hole production in metals and engineered plastics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER25 collet series  -  compatible with standard ER25 chucks and clamping nuts\u003c\/li\u003e\n  \u003cli\u003eTension tap design provides axial float to protect tap integrity during threading cycles\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/8 inch hand taps\u003c\/li\u003e\n  \u003cli\u003eThrough coolant not supported  -  suited for dry or flood coolant external delivery setups\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.19 pounds for minimal spindle load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER25 collet chucks and compatible clamping nuts. Fits 3\/8 inch hand taps as specified in the product data. No additional specific model compatibility data was provided by the manufacturer for this SKU.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator with the spindle powered down and the machine in an e-stop or lockout\/tagout state. The collet seats into a standard ER25 chuck and is secured with the appropriate ER25 clamping nut torqued to the chuck manufacturer's specification. Confirm tap shank diameter matches the collet bore before clamping. Do not use this collet for compression-only or synchronous rigid tapping without verifying the toolholder's intended tapping mode.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Compatibility\u003c\/strong\u003e: 3\/8 inch Hand Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTension Tap\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\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: PARLEC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ERT25-037\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52058647691570,"sku":"ERT25-037","price":99.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc8527b9c170877bbdc18ccc496ca82e_dae2c315-8d64-4df5-b57a-2c4bb2779124.jpg?v=1790039748","url":"https:\/\/voomisupply.com\/products\/parlec-ert25-037-tension-tap-collet-er25-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
