It accepts a 1\/4-inch bore and provides 6 inches of projection from the spindle face, placing the cutting tool at the correct working distance for deep-pocket or extended-reach milling operations. The 25\/32-inch nose diameter keeps the holder compact around the tool. Through-coolant capability channels cutting fluid directly to the tool tip, supporting higher feed rates and longer tool life in ferrous and non-ferrous machining applications. Machinists and CNC setup technicians install this holder as part of a standard CAT50 tooling system.\u003c\/p\u003e\n\u003cp\u003eThis end mill holder is suited for use on CNC vertical and horizontal machining centers equipped with CAT50 spindle interfaces. The 6-inch projection makes it appropriate for operations requiring clearance from the spindle nose, such as deep-pocket milling, contour work, or fixturing around tall workpieces. Through-coolant support makes it compatible with machines that deliver pressurized coolant through the spindle drawbar. It is intended for production and job-shop environments where repeatable tool runout and rigid clamping are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 taper shank for direct mounting in CAT50-equipped machining center spindles\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch bore accommodates standard 1\/4-inch shank end mills and cutting tools\u003c\/li\u003e\n  \u003cli\u003e6-inch projection provides extended reach for deep-cavity and clearance-sensitive setups\u003c\/li\u003e\n  \u003cli\u003e25\/32-inch nose diameter maintains a low-profile clamping zone near the tool shank\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design delivers pressurized cutting fluid directly to the cutting edge\u003c\/li\u003e\n  \u003cli\u003e10-inch overall length for predictable gauge-line-to-tip measurements during setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT50 spindle-interface machining centers that support through-spindle coolant delivery.

Power down and lock out the machining center spindle before changing or seating toolholders. Clean the CAT50 taper and spindle bore thoroughly before insertion to ensure full taper contact and minimize runout. Torque the drawbar and set screw according to the machine tool manufacturer specifications, not those of the holder alone.\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\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 25\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: 22931-6B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52097394770226,"sku":"22931-6B","price":333.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1dfcbcb89c588cc3fdbed3b06183c97b_5e95c078-3b16-498f-a4b2-7b1c2f1b346d.jpg?v=1790066860","url":"https:\/\/voomisupply.com\/products\/techniks-22931-6b-cat50-end-mill-holder-1-4-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
