With a decimal bore size of 0.323 inches and a square drive size of 0.242 inches, this collet provides a secure, positive engagement with the tap shank during threading operations. It is not configured for tension-compression tapping  -  it is a rigid-style collet intended for hand tap holders and CNC or manual machining setups where axial float is not required. Machinists and toolroom technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis collet fits into any ER20-standard collet chuck and is sized specifically for 7\/16 inch hand taps. It is suited for use on CNC machining centers, manual milling machines, and dedicated tapping machines that accept ER20 toolholding systems. The 0.323 inch bore accommodates the round shank of the tap, while the 0.242 inch square recess engages the tap square to prevent rotation under load. This makes it a practical choice for production threading in metal fabrication, maintenance shops, and general machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet series  -  fits any ER20-standard collet chuck or tap holder\u003c\/li\u003e\n  \u003cli\u003e0.323 inch bore diameter sized for 7\/16 inch hand tap shanks\u003c\/li\u003e\n  \u003cli\u003e0.242 inch square drive engages tap square to prevent rotation\u003c\/li\u003e\n  \u003cli\u003eRigid (non-tension) collet  -  no axial float, suited for synchronized tapping\u003c\/li\u003e\n  \u003cli\u003eHand tap configuration  -  not designed for pipe taps\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER20-standard collet chucks and tap holders accepting 7\/16 inch hand taps with a 0.323 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Ensure the collet chuck is fully removed from the spindle or tool turret before inserting or removing the collet. Clean the collet taper and chuck bore before seating to ensure proper runout. Do not exceed the torque rating of the collet nut specified by the chuck manufacturer.\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: ER20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.242 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTension Tap\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 05410-323\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52054616604978,"sku":"05410-323","price":78.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afca159d6e47f6c7030198b38bd783f0_2bb5be7f-ae14-45c9-b083-79b27b54b860.jpg?v=1790037020","url":"https:\/\/voomisupply.com\/products\/techniks-05410-323-er20-tap-collet-0-323-inch-hand-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
