It accepts tooling with a 1-inch bore diameter and provides 3.94 inches of projection from the gauge line, making it suitable for operations that require extended reach without sacrificing rigidity. The adapter includes through-coolant capability with Cool Jet and resealable bores, enabling effective chip evacuation and cutting zone cooling at high spindle speeds. Balanced to 25,000 RPM, this holder is appropriate for high-speed machining centers running demanding finishing or semi-finishing operations. Licensed machinists and CNC setup technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis adapter is used in vertical and horizontal machining centers equipped with CAT50 spindle interfaces. The 1-inch bore diameter accommodates standard shrink-fit tooling shanks of that size, and the 2.28-inch clamping depth ensures secure thermal grip engagement. The 1.73-inch nose diameter and 3.94-inch projection suit applications where clearance around the workpiece or fixture is a consideration. The through-coolant design with resealable bores supports both coolant-on and dry-run configurations depending on the operation.\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 on machining centers\u003c\/li\u003e\n  \u003cli\u003e1-inch bore diameter with 2.28-inch clamping depth for secure shrink-fit tool retention\u003c\/li\u003e\n  \u003cli\u003e3.94-inch projection suitable for extended-reach machining applications\u003c\/li\u003e\n  \u003cli\u003eThrough coolant with Cool Jet technology and resealable bores for flexible coolant routing\u003c\/li\u003e\n  \u003cli\u003eBalanced to 25,000 RPM for stable performance in high-speed cutting operations\u003c\/li\u003e\n  \u003cli\u003e1.73-inch nose diameter designed for clearance in tight workpiece or fixture environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CAT50-spindle machining centers with shrink-fit tooling systems requiring a 1-inch bore holder.

Power down and fully de-energize the machining center before performing any spindle or tooling changes. Confirm spindle and taper surfaces are clean and free of burrs before seating the adapter. Through-coolant port connection and resealable bore plugs should be inspected and properly configured before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: CAT50 Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3.94 inches (100.08 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 2.28 inches (57.91 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.73 inches (43.94 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: 3.847 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.25 x 4.5 x 4.5 inches\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: 50.840.1Z.4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HAIMER","offers":[{"title":"Default Title","offer_id":67911601783090,"sku":"50.840.1Z.4","price":687.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9120faeb55e679fd5298ad9c23de84c4_46fc34ab-46ef-408b-af0b-d695915127f2.jpg?v=1791213499","url":"https:\/\/voomisupply.com\/products\/haimer-50-840-1z-4-shrink-fit-adapter-cat50-1-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
