It accepts CNMG 432 inserts secured by a clamp and pin holding method, providing rigid, repeatable insert positioning during facing, milling, and turning applications. The shank measures 3\/4 inches wide by 3\/4 inches tall with an overall length of 4.5 inches. A -5 degree rake angle and right-hand cutting direction make this holder suited for aggressive material removal on a broad range of workpiece materials. Licensed machinists and CNC lathe operators are the primary installers and users of this toolholder.\u003c\/p\u003e\u003cp\u003eThis toolholder is built for general-purpose turning center and lathe applications across a wide range of workpiece materials including ferrous metals, non-ferrous metals, stainless, heat-resistant alloys, and cast materials. The universal primary workpiece material rating corresponds to material codes H, K, M, N, P, and S. It fits the Multi-Option series and is well-suited for production environments where consistent insert changeover speed and rigidity are required. The head length is 1.0 inch and the back-of-bar to cutting edge dimension is 1.25 inches, providing predictable tool offset for programmed cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMCLN toolholder style with -5 degree rake angle for controlled negative-rake cutting geometry\u003c\/li\u003e\n\u003cli\u003eAccepts CNMG 432 inserts with 1\/2 inch inscribed circle and 0.1875 inch thickness\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding method for secure, repeatable seating under heavy cutting loads\u003c\/li\u003e\n\u003cli\u003e3\/4 inch by 3\/4 inch square shank fits standard lathe and turning center tool blocks\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; rated for facing, milling, and turning operations\u003c\/li\u003e\n\u003cli\u003eNo coolant-through feature; compatible with external coolant delivery setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept CNMG 432 inserts with compatible insert size code CN43 and an inscribed circle of 1\/2 inch.

Before changing inserts or mounting the toolholder, power down and lock out the machine per standard lockout\/tagout procedures. Secure the shank fully into the tool block or turret to the manufacturer-recommended engagement depth before torquing the clamping fasteners. Inspect the insert seat and locating pin for debris or wear before seating a new CNMG 432 insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MCLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CNMG 432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: CN43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Facing, Milling, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multi-Option\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.72 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: U101624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51728508256562,"sku":"U101624","price":145.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ecd8f0cd07fee6e5335d375f42712f6.jpg?v=1788692363","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101624-mcln-turning-toolholder-cnmg-432","provider":"Voomi Supply","version":"1.0","type":"link"}
