With a 0.75 inch pilot diameter and a 1.75 inch nose diameter, it securely locates and drives shell-style cutters in high-load milling operations. Through-coolant capability routes cutting fluid directly to the cutting zone, supporting longer tool life and better chip evacuation. At 5.119 inches overall length and 2.43 pounds, this holder suits vertical and horizontal machining centers running production or job-shop face milling work. Licensed machinists and CNC setup technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis shell mill holder fits CAT40 spindle interfaces found on a wide range of vertical machining centers and horizontal machining centers used in production and job-shop environments. The 0.75 inch pilot and 1.75 inch nose diameter accommodate correspondingly sized shell mill arbor bores. The through-coolant port makes it well-suited for materials and cutting conditions where flood-only coolant delivery is insufficient. It is sold individually with a minimum order quantity of one unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for direct spindle mounting on compatible machining centers\u003c\/li\u003e\n\u003cli\u003e0.75 inch pilot diameter for positive cutter location and drive\u003c\/li\u003e\n\u003cli\u003e1.75 inch nose diameter supports standard shell mill arbor bores\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability for improved chip evacuation and tool life\u003c\/li\u003e\n\u003cli\u003e5.119 inch overall length with 1.75 inch projection from flange to nose end\u003c\/li\u003e\n\u003cli\u003eSold individually — minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CAT40 spindle-interface machining centers requiring a 0.75 inch pilot shell mill holder with through-coolant capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom technician with the machine powered down and the spindle locked before mounting or removing the holder. Use a calibrated torque wrench and the appropriate retention knob for CAT40 tooling when securing the holder in the spindle. Inspect the taper shank and spindle bore for nicks, burrs, or contamination before seating the holder, as surface defects directly affect runout and tool life. Follow the machine tool manufacturer guidelines for drawbar force and retention knob specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.119 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection Flange to Nose End\u003c\/strong\u003e: 1.75 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: 2.43 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.61 inches L x 3.31 inches W x 3.31 inches H\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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03197129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558015992114,"sku":"03197129","price":223.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ccc0e608eb564ab2939d2adb83bcf02_d5d8fb68-4117-4889-85f9-8cb3575ee952.jpg?v=1786400915","url":"https:\/\/voomisupply.com\/products\/seco-03197129-shell-mill-holder-cat40-0-75-inch-pilot","provider":"Voomi Supply","version":"1.0","type":"link"}
