The holder accepts a 1-inch bore and features a 2-inch nose diameter with a 6-inch projection, giving it an overall length of 8.687 inches. A 5\/8-11 drawbar thread secures the holder to the spindle. It is balanced to 12000 RPM, making it suitable for high-speed milling operations on CNC machining centers. Machinists and toolroom technicians install this holder in CAT40-spindle machines for face milling, end milling, and slotting work where coolant-through capability is required.\u003c\/p\u003e\n\u003cp\u003eThis end mill holder is used in production and job-shop environments running CAT40-equipped vertical and horizontal machining centers. The 6-inch projection accommodates deep-reach applications where standard-length holders cannot clear fixtures or part features. Through-spindle coolant is routed directly to the cutting zone, supporting chip evacuation and tool life in ferrous and non-ferrous machining. The 4.43-inch clamping depth provides secure grip on compatible end mill shanks. This holder is appropriate for both roughing and finishing operations where vibration control and coolant delivery are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for direct spindle mounting on standard CNC machining centers\u003c\/li\u003e\n  \u003cli\u003e1-inch bore accommodates end mills with 1-inch straight shanks\u003c\/li\u003e\n  \u003cli\u003e6-inch projection enables deep-reach milling where clearance is limited\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant delivery routes coolant directly to the cutting edge\u003c\/li\u003e\n  \u003cli\u003eBalanced to 12000 RPM for stable high-speed operation\u003c\/li\u003e\n  \u003cli\u003e4.43-inch clamping depth provides solid tool retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CAT40-spindle CNC machining centers accepting a 5\/8-11 drawbar thread.

Verify spindle is powered down and locked out before mounting or removing any toolholder. Use a calibrated torque wrench and the machine manufacturer-specified drawbar torque procedure when securing the holder. Inspect the taper bore and spindle taper for nicks, chips, or contamination before assembly, as surface defects will affect runout and balance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2 inches\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: 8.687 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 4.43 inches\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\u003eDrawbar Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 12000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.64 pounds\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1013425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730106384690,"sku":"1013425","price":246.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bfa8eb44e524b511b554fe8d54c54d6_05245d3d-8d26-4d32-ab2b-8a0bb6b13796.jpg?v=1788711827","url":"https:\/\/voomisupply.com\/products\/kennametal-1013425-cat40-end-mill-holder-1-in-hole","provider":"Voomi Supply","version":"1.0","type":"link"}
