The adapter features a 1.5-inch inside hole diameter and a 4.5-inch projection, providing the reach needed for deep-pocket or extended-tool applications. Through-coolant capability allows cutting fluid to be delivered directly to the cutting edge, improving chip evacuation and extending tool life in demanding metal-cutting operations. This adapter is installed by machinists and toolroom technicians working with CAT50-spindle machines.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for use in industrial and production machining environments, including job shops and manufacturing facilities running CAT50-spindle vertical or horizontal machining centers. The straight shank with flat configuration accepts standard end mill holders and similar tooling. The through-coolant design makes it a strong fit for deep-bore drilling, reaming, and milling operations where flood coolant alone is insufficient to clear chips or control heat at the cutting zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT50 taper interface for positive spindle engagement and repeatable tool positioning\u003c\/li\u003e\n\u003cli\u003e1.5-inch inside hole diameter accommodates large-shank tooling\u003c\/li\u003e\n\u003cli\u003e4.5-inch projection provides extended reach for deep-pocket machining\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design delivers coolant directly to the cutting edge\u003c\/li\u003e\n\u003cli\u003eStraight shank with flat design for secure set-screw clamping\u003c\/li\u003e\n\u003cli\u003e2.75-inch nose diameter for rigidity and vibration damping at the spindle face\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT50-spindle machining centers requiring a straight shank with flat tool holder.

Ensure the taper and spindle bore are clean and free of chips or coolant residue before seating the adapter. Verify the drawbar is properly torqued to spindle manufacturer specifications before resuming operation. Do not exceed the toolholder rated speed or overhang limits specified by the machine builder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Hole Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrawbar Thread Size\u003c\/strong\u003e: 1-8 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: 10.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112811\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1749475\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732498055474,"sku":"1749475","price":569.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d2d55288d00820367776cb6709486ed_faa2cc60-e960-411f-84a1-1bc190c9c14e.jpg?v=1788743616","url":"https:\/\/voomisupply.com\/products\/kennametal-1749475-cat50-straight-shank-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
