It accepts a 3\/8 inch bore and delivers a 3 inch projection from the spindle face, positioning the cutting tool at a consistent and repeatable standout. The nose diameter measures 7\/8 inch. With an overall length of 5.687 inches and a weight of 2.6 pounds, this holder is built for rigid, accurate tool clamping in production milling environments. Licensed machinists and toolroom technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis end mill holder is suited for vertical and horizontal CNC machining centers running CAT40 spindles. The 3 inch projection makes it appropriate for applications where clearance is needed between the spindle and the workpiece or fixture. It accepts end mills and shank-style cutting tools with a 3\/8 inch shank diameter. No through-coolant capability is present, so coolant delivery must be handled externally or through an alternative method. Typical applications include general-purpose profiling, slotting, and peripheral milling in job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for compatibility with CAT40 spindle tooling systems\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch bore diameter for standard shank end mills and cutting tools\u003c\/li\u003e\n  \u003cli\u003e3 inch projection provides standout clearance from spindle face\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch nose diameter for secure, rigid tool clamping\u003c\/li\u003e\n  \u003cli\u003eOverall length of 5.687 inches for predictable tool offset entry\u003c\/li\u003e\n  \u003cli\u003eNo through-coolant  -  suitable for external or flood coolant setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling holder for CNC machining centers equipped with CAT40 spindle interfaces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machining center spindle before inserting or removing any toolholder. Use a calibrated torque wrench and the appropriate pull stud for your machine when securing the holder in the spindle. Inspect the taper shank and spindle bore for nicks, chips, or contamination before seating the holder to ensure full contact and runout accuracy.\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\u003eBore Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.687 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.6 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: TECHNIKS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CAT40SLN3\/8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51973496242482,"sku":"CAT40SLN3\/8","price":105.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b97a2679c9a9a5ceb4d7b3e46189b41d_24ad8614-3ded-4226-ba7d-08069bb62785.jpg?v=1789973486","url":"https:\/\/voomisupply.com\/products\/techniks-cat40sln3-8-end-mill-holder-cat40-3-8-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
