It accepts shell mills via a standard pilot bore connection, transmitting torque and maintaining precise cutter alignment during heavy face milling operations. The pilot diameter measures 19.05 millimeters with a nose diameter of 44.45 millimeters, and the overall length reaches 187.30 millimeters. Through-coolant capability is built in, directing cutting fluid directly to the cutting zone for improved chip evacuation and tool life. This holder is installed by CNC machinists and toolroom technicians working with CAT40-spindle vertical or horizontal machining centers.\u003c\/p\u003e\u003cp\u003eThe 10008257 is suited for production and job-shop environments running shell mills on CAT40-taper machining centers. The through-coolant feature makes it appropriate for applications where heat buildup and chip control are critical concerns, such as steel and cast iron face milling. A projection from flange to nose end of 100.00 millimeters provides clearance for workholding fixtures in typical setups. This holder ships as a single unit and is cataloged as a replacement or web-only SKU.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 TF ADB taper shank for direct spindle mounting on CAT40-equipped machining centers\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capable, routing fluid to the cutting zone without external adapters\u003c\/li\u003e\n\u003cli\u003e19.05 mm pilot diameter for precise shell mill registration and repeatable cutter positioning\u003c\/li\u003e\n\u003cli\u003e100.00 mm projection from flange to nose end accommodates workholding clearance in standard setups\u003c\/li\u003e\n\u003cli\u003e44.45 mm nose diameter supports a range of common shell mill bore sizes\u003c\/li\u003e\n\u003cli\u003eOverall length of 187.30 mm suits standard CAT40 spindle reach requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style shell mill holder for machining centers equipped with a CAT40 taper spindle interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified CNC machinist or toolroom technician. The spindle must be fully stopped and the machine placed in a safe, locked-out state before mounting or removing the holder. Proper drawbar torque should be applied according to the machining center manufacturer specifications. Inspect the taper shank and spindle bore for contamination or damage before seating the holder to ensure accurate tool runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40 TF ADB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 187.30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection Flange to Nose End\u003c\/strong\u003e: 100.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 19.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 44.45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 14.96 inches (L) x 3.23 inches (W) x 3.23 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.73 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10008257\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562371711282,"sku":"10008257","price":362.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb28015b35cbe0a8c09042990ddd54ff_22c6c45b-94d4-4b3e-a366-5aa2614a5ade.jpg?v=1786475874","url":"https:\/\/voomisupply.com\/products\/seco-10008257-shell-mill-holder-cat40-tf-adb","provider":"Voomi Supply","version":"1.0","type":"link"}
