Tap collets secure taps within a tapping chuck or holder, transmitting torque while allowing controlled axial float to prevent tap breakage during threading operations. This collet features a Total Indicator Runout (TIR) of 0.001 inches, which helps maintain thread accuracy and concentricity in precision tapping applications. The square drive measures 0.286 inches and is configured for hand tap geometry. Machinists and tool-and-die professionals install this collet in compatible tapping heads on manual or CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for standard hand tapping operations in production machining, maintenance, and toolroom environments. It is designed for use without through-coolant and does not support tension-compression tapping configurations. Typical applications include threading ferrous and non-ferrous workpieces where consistent thread quality and low runout are required. The Series L designation identifies the collet series family, which determines compatibility with the corresponding tapping chuck or holder body.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble angle collet design for secure tap retention and accurate seating\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.001 inches for consistent thread concentricity\u003c\/li\u003e\n  \u003cli\u003e0.381-inch collet size accepts standard 3\/8-inch hand taps\u003c\/li\u003e\n  \u003cli\u003eSquare drive size of 0.286 inches for positive torque transmission\u003c\/li\u003e\n  \u003cli\u003eSeries L designation for direct fitment into compatible L-series tapping holders\u003c\/li\u003e\n  \u003cli\u003eSold individually — package quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Series L tapping chucks and holders that accept double angle tap collets.

Inspect the collet bore and seating surfaces for chips or wear before installation, as contamination will increase runout and reduce tap life. Ensure the tap shank and square drive are clean and fully seated before securing the collet. Follow the tapping chuck manufacturer's torque and assembly procedures for the specific holder body in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: Double Angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Drive Size\u003c\/strong\u003e: 0.286 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.001 inches (0.0300 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\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: 0.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1016591\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51751115292978,"sku":"1016591","price":98.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41e88ee397bd98ec962eb9db54d460a9.jpg?v=1788921741","url":"https:\/\/voomisupply.com\/products\/kennametal-1016591-tap-collet-series-l-0-381-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
