It accepts tooling with a 0.5-inch bore diameter and delivers a 6.3-inch projection from gauge line, making it well-suited for extended-reach machining operations. The holder is balanced to 25,000 RPM and features through-coolant capability with Cool Jet and resealable bores, supporting high-speed, high-precision cutting applications. Machinists and tool room technicians working in production or aerospace environments install this type of holder where runout control and balance grade matter.\u003c\/p\u003e\u003cp\u003eThis adapter is used in vertical and horizontal machining centers equipped with CAT40 spindle interfaces. It is appropriate for applications requiring extended reach with a 0.5-inch tool shank, such as deep-pocket milling, drilling, or finishing passes where a standard-length holder would interfere with the workpiece or fixture. The 1.85-inch clamping depth ensures secure tool retention under load, and the 0.94-inch nose diameter is compatible with shrink-fit induction heating stations designed for this bore class.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for direct spindle mounting on standard machining centers\u003c\/li\u003e\n\u003cli\u003e0.5-inch (12.70 mm) bore diameter with 1.85-inch (46.99 mm) clamping depth for firm tool grip\u003c\/li\u003e\n\u003cli\u003e6.3-inch (160.02 mm) overall projection for extended-reach operations\u003c\/li\u003e\n\u003cli\u003eBalanced to 25,000 RPM for high-speed spindle compatibility\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with Cool Jet and resealable bore technology\u003c\/li\u003e\n\u003cli\u003e0.94-inch nose diameter suited for standard shrink-fit heating equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a shrink-fit tool holder adapter for CAT40 taper machining center spindles accepting 0.5-inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires an induction shrink-fit heating station rated for the bore diameter and holder material  -  never use open flame to expand the bore. Power down and lock out the machining center spindle before mounting or removing the holder. Verify balance grade and RPM rating do not exceed the spindle manufacturer specifications before operation. Through-coolant connection should be confirmed leak-free at the machine spindle interface before running the program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: CAT40 Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 6.3 inches (160.02 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 1.85 inches (46.99 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.94 inches (23.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes, 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: 1.682 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 40.842.1\/2Z.4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HAIMER","offers":[{"title":"Default Title","offer_id":67906027618610,"sku":"40.842.1\/2Z.4","price":625.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6ac113a519d713a065e648351f39924.jpg?v=1791163165","url":"https:\/\/voomisupply.com\/products\/haimer-40-842-1-2z-4-shrink-fit-holder-cat40-0-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
