It accepts a shell mill via a standard pilot interface and transmits torque from the spindle to the cutter with high rigidity. The holder features through-coolant capability, allowing cutting fluid to be delivered directly to the cutting zone for improved chip evacuation and tool life. With an overall length of 187.30 mm and a pilot diameter of 25.40 mm, this holder is suited to medium-duty face milling and shoulder milling applications. It is installed and serviced by machinists and CNC tooling technicians working in job shops, production machining environments, and toolrooms.\u003c\/p\u003e\n\u003cp\u003eThis shell mill holder is intended for use in CAT40 spindle machines, which are common in vertical and horizontal machining centers across general metalworking, aerospace component manufacturing, and precision parts production. The projection from flange to nose end is 100.00 mm, making it appropriate for applications that require moderate gage length. The nose diameter of 57.15 mm accommodates shell mill bodies designed for that pilot size. Through-coolant routing makes it well suited to high-feed or dry-sensitive materials where flood cooling alone is insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 TF ADB taper shank for direct spindle mounting on CAT40 machining centers\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability delivers cutting fluid to the tool nose for improved thermal management and chip removal\u003c\/li\u003e\n  \u003cli\u003ePilot diameter of 25.40 mm for positive shell mill registration and repeatable runout\u003c\/li\u003e\n  \u003cli\u003eNose diameter of 57.15 mm accommodates standard shell mill body bores\u003c\/li\u003e\n  \u003cli\u003eFlange-to-nose projection of 100.00 mm provides balanced reach without excessive overhang\u003c\/li\u003e\n  \u003cli\u003eWeighs 7.14 pounds, indicating a robust steel construction appropriate for production environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style shell mill holder for CAT40 spindle machining centers using the TF ADB taper standard.

Power down and lock out the machine spindle before inserting or removing the holder. Use a properly rated pull stud torqued to the spindle manufacturer's specification and verify that the taper interface is clean and free of chips or burrs before seating. Confirm through-coolant port alignment with the machine spindle coolant circuit before operation.\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 TF ADB\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: 25.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 57.15 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: 8.27 inches L x 2.95 inches W x 2.95 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.14 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10008258\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558237045042,"sku":"10008258","price":372.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb28015b35cbe0a8c09042990ddd54ff.jpg?v=1786406927","url":"https:\/\/voomisupply.com\/products\/seco-10008258-shell-mill-holder-cat40-tf-adb","provider":"Voomi Supply","version":"1.0","type":"link"}
