Built with a taper shank interface, the holder provides rigid, repeatable tool holding suitable for high-speed milling operations. It features a 3-inch projection, a 1-3\/4 inch nose diameter, and a 2.25 inch flange diameter. Through-spindle and DIN flange coolant compatibility supports both flood and directed coolant strategies, making this holder a practical choice for shops running production milling with coolant-intensive toolpaths. Machinists and toolroom technicians install this holder as part of a standard CAT40 tooling assembly.\u003c\/p\u003e\u003cp\u003eThe 75022 is suited for use on CNC vertical and horizontal machining centers equipped with a CAT40 spindle taper. The 3-inch projection accommodates applications where clearance from the spindle face is needed, such as deep-pocket milling or setups with workholding interference. The 20 mm bore diameter accepts standard 20 mm shank end mills. Through-coolant capability supports consistent chip evacuation and tool life in ferrous and non-ferrous cutting applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for compatibility with standard CAT40 machining center spindles\u003c\/li\u003e\n\u003cli\u003e3-inch projection for extended reach in deep-pocket and obstructed setups\u003c\/li\u003e\n\u003cli\u003e20 mm bore diameter accommodates standard 20 mm shank cutting tools\u003c\/li\u003e\n\u003cli\u003eThrough-spindle and DIN flange coolant delivery for directed coolant at the cutting zone\u003c\/li\u003e\n\u003cli\u003e1-3\/4 inch nose diameter and 2.25 inch flange diameter for stable tool clamping geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT40 spindle taper machining centers accepting standard end mill holders with through-coolant capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Power down and lock out the machining center spindle before mounting or removing the holder. Use a calibrated torque wrench and the appropriate CAT40 retention knob when securing the holder in the spindle. Verify coolant port alignment and check for runout with a dial indicator before beginning a cutting operation.\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\u003eOverall Length\u003c\/strong\u003e: 5.687 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 2.25 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 and DIN Flange\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COLLIS TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75022\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67906181169458,"sku":"75022","price":248.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35b4ab2000d00c2a8ad3ceb413ea66ea.jpg?v=1791165823","url":"https:\/\/voomisupply.com\/products\/collis-tool-75022-cat40-end-mill-holder-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
