The holder accepts a 1-1\/4 inch bore and delivers through-spindle coolant directly to the cutting zone, reducing heat buildup and extending tool life. With a 2-inch projection, a 2-1\/4 inch nose diameter, and a drawbar thread size of 5\/8-11, this holder is built for production milling environments. It is balanced to 12,000 RPM, making it suitable for high-speed operations on vertical and horizontal machining centers. Machinists and CNC setup technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis end mill holder is suited for use in production and job-shop CNC machining environments running CAT40 spindle tooling. The 1-1\/4 inch hole accommodates end mills and cutting tools with matching shank diameters. The through-coolant feature supports high-pressure coolant delivery through the spindle, which is particularly useful in deep-cavity milling, difficult-to-cut materials, and high-feed applications where flood cooling is insufficient. The 2-inch projection provides adequate clearance for a range of workpiece geometries without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for direct mounting in CAT40 spindle machines\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch bore diameter accommodates standard end mill shanks\u003c\/li\u003e\n\u003cli\u003eThrough-spindle coolant delivery via internal coolant channel\u003c\/li\u003e\n\u003cli\u003eBalanced to 12,000 RPM for high-speed milling applications\u003c\/li\u003e\n\u003cli\u003e2-inch projection with 2.35 inches of clamping depth for secure grip\u003c\/li\u003e\n\u003cli\u003e5\/8-11 drawbar thread for standard CAT40 retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers equipped with CAT40 spindle interfaces and through-spindle coolant capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by CNC machinists or toolroom technicians. The machine spindle must be powered down and the tool changer disabled before mounting or removing this holder. Use the appropriate torque wrench on the drawbar to the machine manufacturer's specification — do not over-tighten or impact-drive the drawbar. Verify coolant port alignment with the spindle before use to ensure proper through-coolant flow.\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: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 2.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.687 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrawbar Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 12,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.44 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1013426\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732812890418,"sku":"1013426","price":190.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bfa8eb44e524b511b554fe8d54c54d6_a18098c6-b0f0-460d-9d8b-6e7e58aafa98.jpg?v=1788747111","url":"https:\/\/voomisupply.com\/products\/kennametal-1013426-end-mill-holder-cat40-1-1-4in","provider":"Voomi Supply","version":"1.0","type":"link"}
