It accepts end mills with a 20mm bore diameter and provides a 3-inch projection from the spindle face, placing the cutting tool at a consistent, repeatable gage length. The 52mm nose diameter and 5.687-inch overall length make this holder well-suited for standard milling operations where rigidity and runout control are priorities. Installation is handled by machinists and toolroom technicians working with CAT40-spindle vertical or horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis holder fits CAT40-taper spindle machining centers running end mills, slot drills, and similar straight-shank rotary cutting tools with a 20mm shank diameter. The 3-inch projection suits applications where moderate tool stick-out is needed to clear workpiece fixtures or part features without requiring an extended-reach holder. Solid construction supports high-speed and high-feed milling passes in production and job-shop environments alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for direct spindle mounting on compatible machining centers\u003c\/li\u003e\n  \u003cli\u003e20mm bore diameter accommodates standard 20mm shank end mills\u003c\/li\u003e\n  \u003cli\u003e3-inch (3.0000 inch) projection for consistent gage length setup\u003c\/li\u003e\n  \u003cli\u003e52mm nose diameter provides a robust clamping body\u003c\/li\u003e\n  \u003cli\u003e5.687-inch overall length suits typical vertical and horizontal CNC setups\u003c\/li\u003e\n  \u003cli\u003eNo through-coolant passage  -  external coolant delivery required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style end mill holder for CNC machining centers equipped with a CAT40-taper spindle interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or toolroom technician should install this holder using a proper CAT40 pull-stud and a calibrated torque wrench rated for the spindle draw-bar specification of the target machine. Always de-energize and lock out the machining center spindle before changing tooling. Inspect the taper bore and spindle taper for chips or contamination before seating the holder, and verify runout with a dial indicator after clamping to confirm acceptable concentricity before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 20mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 52mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.687 inches\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: 3 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: 22973\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51973921669426,"sku":"22973","price":171.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21b29759f59ea55f0b97fefadebd39ec_d485117d-6a98-48f9-bfbe-ea4b062c78c6.jpg?v=1789975065","url":"https:\/\/voomisupply.com\/products\/techniks-22973-end-mill-holder-cat40-3-inch-projection","provider":"Voomi Supply","version":"1.0","type":"link"}
