The holder accepts a 0.25 inch hole diameter and provides a 6.3 inch overall projection from gauge line, making it well-suited for deep-reach operations. It is balanced to 25,000 RPM and includes through-coolant capability with Cool Jet and resealable bore technology. Installation and setup are performed by toolroom technicians and CNC setup specialists using induction shrink-fit equipment.\u003c\/p\u003e\n\u003cp\u003eThis adapter is used in precision machining environments where high rotational speeds and tight runout tolerances are required. The CAT50 taper shank fits standard CAT50 spindle interfaces found on vertical and horizontal machining centers in both production and job shop settings. The 1.42 inch clamping depth provides strong grip engagement on tool shanks, and the 0.83 inch nose diameter allows access to workpiece features without excessive interference. The through-coolant design supports directed coolant delivery at the cutting zone, improving chip evacuation and tool life in demanding cutting operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 taper shank for compatibility with standard CAT50 spindle interfaces\u003c\/li\u003e\n  \u003cli\u003e0.25 inch hole diameter with 1.42 inch clamping depth for secure tool grip\u003c\/li\u003e\n  \u003cli\u003e6.3 inch projection for extended reach in deep-cavity machining\u003c\/li\u003e\n  \u003cli\u003eBalanced to 25,000 RPM for high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capable with Cool Jet and resealable bore design\u003c\/li\u003e\n  \u003cli\u003e0.83 inch nose diameter for reduced interference in tight workpiece areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style shrink-fit tool holder adapter for use with CAT50 spindle taper machining centers requiring a 0.25 inch bore shrink-fit holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a dedicated induction shrink-fit heating unit to thermally expand the bore before inserting the tool shank. Allow the holder to cool completely and reach thermal equilibrium before mounting it in the spindle. Always verify spindle and holder tapers are clean and free of burrs or debris before seating. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when working with induction heating equipment.\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: CAT50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.3 inches (160.02 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 6.3 inches (160.02 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 1.42 inches (36.07 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.83 inches (21.08 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdditional Features\u003c\/strong\u003e: With Cool Jet and Resealable Bores\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 25,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.609 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: HAIMER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 50.842.1\/4Z.4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HAIMER","offers":[{"title":"Default Title","offer_id":67912086847794,"sku":"50.842.1\/4Z.4","price":827.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9120faeb55e679fd5298ad9c23de84c4_9532f96f-1071-4cdb-8e6a-f770098932f6.jpg?v=1791226894","url":"https:\/\/voomisupply.com\/products\/haimer-50-842-1-4z-4-shrink-fit-tool-holder-cat50","provider":"Voomi Supply","version":"1.0","type":"link"}
