It accepts WNMG 432 inserts secured by a clamp and pin holding method, providing rigid, repeatable positioning during external turning operations. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches. This toolholder is designed for use on CNC lathes and manual turning centers where controlled, negative-rake cutting geometry is required. Installation and setup are handled by machining technicians and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for external turning applications in both production and job-shop environments. The right-hand cutting direction makes it compatible with standard spindle rotation on conventional lathe setups. With a head length of 1.25 inches and a back-of-bar to cutting edge distance of 1.25 inches, it positions the WNMG 432 insert precisely for consistent depth-of-cut control. It is part of the Sumitomo Multi-Option series, intended for shops that standardize on WNMG insert geometry across multiple operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMWLN toolholder style with -5 degree negative rake angle for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eAccepts WNMG 432 inserts — secured by clamp and pin method for positive insert location\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe spindle rotation\u003c\/li\u003e\n\u003cli\u003e1 inch by 1 inch shank cross-section for use in standard tool posts and turrets\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with 1.25 inch head length and 1.25 inch back-of-bar to cutting edge\u003c\/li\u003e\n\u003cli\u003eNo coolant-through — designed for external coolant delivery or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept WNMG 432 inserts.

Ensure the lathe or turning center is fully powered down and locked out before changing toolholders or inserts. Verify that the shank fits the tool post or turret pocket to the correct depth and that clamping hardware is torqued according to the machine manufacturer's specifications. Inspect the clamp and pin components for wear before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MWLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WNMG 432\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\u003eShank Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.25 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\u003eCoolant Through\u003c\/strong\u003e: No\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: 1.7 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: U101740\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51727091269938,"sku":"U101740","price":155.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b3fbce25fa79043830c12bbf8f0fef9.jpg?v=1788673149","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101740-mwln-turning-toolholder-wnmg-432","provider":"Voomi Supply","version":"1.0","type":"link"}
