It features a 1 inch by 1 inch square shank and an overall length of 6 inches, making it well-suited for standard tool post and turret applications. The toolholder operates at a negative 5-degree rake angle and uses a clamp-and-screw insert holding method for secure, repeatable insert seating. It accepts WN..43. series inserts with a 0.5 inch inscribed circle. Constructed from steel, this toolholder is built for rigidity under interrupted cuts and continuous turning passes. Machinists and tool-and-die professionals install this holder on manual lathes and CNC turning centers alike.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for external turning applications where a left-hand cutting direction is required. The MWLN style positions the insert at a 5-degree lead angle, directing cutting forces toward the spindle for improved stability. It is a practical choice for shops running general-purpose turning on steel, cast iron, and similar materials where negative rake inserts deliver longer edge life under heavier feeds. The back of bar to cutting edge distance is 1.25 inches, and the head length measures 1.13 inches, providing predictable tool nose positioning during setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand MWLN toolholder style with negative 5-degree rake angle\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert holding method for secure insert retention under load\u003c\/li\u003e\n\u003cli\u003eAccepts WN..43. series inserts with 0.5 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003e1 inch x 1 inch square steel shank for rigid tool post and turret mounting\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with 1.13 inch head length and 1.25 inch back-of-bar to cutting edge\u003c\/li\u003e\n\u003cli\u003ePart of the Multi-Option series for broad insert compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept WN..43. series inserts, specifically WN..432 geometry, with a 0.5 inch inscribed circle.

Secure the toolholder shank fully within the tool post or turret block to the manufacturer-recommended engagement depth before tightening. Power down and lock out the machine spindle before changing inserts or adjusting the holder. Inspect the insert pocket and clamping screw for wear or damage each time an insert is indexed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MWLN\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 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: 1.13 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 Inscribed Circle\u003c\/strong\u003e: 0.5 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WN..43.
