Part of the Kennametal Kenloc series, it accepts WN..43. inserts secured by a clamp and screw holding method, providing rigid, repeatable insert location under heavy cutting loads. The toolholder features a 5-degree lead angle and a negative 5-degree rake angle, making it well suited for interrupted cuts, hard materials, and applications where insert edge strength is the priority. Manufactured from steel, it delivers the rigidity machinists expect in production turning environments.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for use in metal-cutting operations where a left-hand tool path is required, such as turning toward the tailstock or machining specific shoulder geometries. It fits standard square-shank tool posts and turrets sized for 1-1\/4 inch shank tooling. Typical users include CNC lathe operators, manual lathe machinists, and toolroom technicians working in job shops, production facilities, and aerospace or industrial component manufacturing environments. Coolant-through capability is not available on this holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand holder orientation for turning away from the chuck or toward the tailstock\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of -5 degrees promotes insert edge strength for interrupted cuts and hard materials\u003c\/li\u003e\n\u003cli\u003eKenloc clamp-and-screw insert holding method provides rigid, secure insert seating\u003c\/li\u003e\n\u003cli\u003eAccepts WN..43.

Ensure the machine spindle is fully stopped and all stored energy is released before mounting or changing toolholders. Secure the shank fully within the tool post or turret to the recommended clamping depth to prevent deflection under cutting forces. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool height and offset values.\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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Kenloc\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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1.25 inches\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: 1.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.5 inches\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 Compatibility\u003c\/strong\u003e: WN..43. \/ WN.. 432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.61 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1095990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744842481970,"sku":"1095990","price":192.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/491018a1a83457e9d5b940e2013c7990.jpg?v=1788861374","url":"https:\/\/voomisupply.com\/products\/kennametal-1095990-mwln-left-hand-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
