It uses a CAT50 taper shank interface and accepts tooling with a 3\/4-inch (19.05 mm) bore diameter. Hydraulic clamping technology delivers consistent gripping force and excellent vibration damping, making it well suited for finishing operations and high-speed cutting where runout control is critical. The chuck is balanced to 25,000 RPM and features a total indicator runout (TIR) of 0.003 mm, supporting tight-tolerance work. Through-coolant capability directs cutting fluid directly to the tool tip for effective chip evacuation and heat management.\u003c\/p\u003e\u003cp\u003eThis chuck is intended for use on CAT50-spindle machining centers in production and job-shop environments. It is a direct-mount toolholder requiring no additional adapters when paired with a compatible CAT50 spindle. The 81 mm projection and 41.5 mm clamping depth accommodate a wide range of end mills, drills, and reamers in standard 3\/4-inch shank diameter. Machinists, tooling engineers, and CNC setup technicians are the primary users in both vertical and horizontal machining center configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT50 taper shank for direct mounting on CAT50-spindle machining centers\u003c\/li\u003e\n\u003cli\u003eHydraulic clamping mechanism provides consistent grip force and vibration damping\u003c\/li\u003e\n\u003cli\u003eBalanced to 25,000 RPM for high-speed machining applications\u003c\/li\u003e\n\u003cli\u003eTIR of 0.003 mm supports tight-tolerance and finishing operations\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design routes fluid directly to the cutting zone\u003c\/li\u003e\n\u003cli\u003e41.5 mm clamping depth and 81 mm projection for flexible tooling reach\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT50-spindle CNC machining centers accepting standard CAT50 taper toolholders and 3\/4-inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the spindle drive before mounting or removing the toolholder. Use a calibrated torque wrench and follow the machine tool manufacturer's draw bar torque specification when securing the chuck in the spindle. Inspect the taper bore and shank for contamination or damage before seating the holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: CAT50\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: 3\/4 inch (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 55.50 mm (2.1850 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1.0591 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 81.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 41.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To RPM\u003c\/strong\u003e: 25,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.003 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 2.01 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCHUNK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1447937\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHUNK","offers":[{"title":"Default Title","offer_id":67910874759474,"sku":"1447937","price":564.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1bc8f4bb42e701a240ab4ebb6e7210c.jpg?v=1791201036","url":"https:\/\/voomisupply.com\/products\/schunk-1447937-hydraulic-tool-chuck-cat50-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
