Kennametal 1095986 Mwln Left Hand Turning Toolholder

Product Description

The KENNAMETAL 1095986 is a left-hand MWLN-style indexable turning toolholder designed for negative rake external turning operations on CNC and manual lathes. Built on the Kenloc series platform, it features a clamp-and-screw insert holding method that provides rigid, repeatable seating for WN..43. style inserts. The toolholder is machined from steel and carries a -5 degree rake angle, making it suited for stable, high-feed roughing and finishing passes on a wide range of workpiece materials. The 1 inch by 1 inch square shank fits standard toolpost and turret pockets commonly found on mid-size turning centers.

This toolholder is intended for use in production turning environments where left-hand approach geometry is required, such as turning toward the tailstock or facing from center outward. It accepts WN..43. inserts, specifically WN.. 432 complete insert compatibility, giving machinists access to a broad selection of carbide grades and chip-breaker geometries. The 5 degree lead angle promotes chip control and reduces entry shock during interrupted or continuous cuts. Coolant-through capability is not available on this holder.

Key Features

• Left-hand holder orientation for turning toward the tailstock or specific approach directions
• Negative -5 degree rake angle for increased cutting-edge strength on demanding materials
• Clamp and screw insert retention for secure, high-rigidity insert seating
• Accepts WN..43. style inserts with 0.5 inch inscribed circle
• 1 inch x 1 inch square shank for compatibility with standard turret and toolpost pockets
• Steel construction for durability in continuous production use

Compatibility

Designed for use with WN..43. style indexable inserts, with complete insert compatibility noted as WN.. 432. The 1 inch x 1 inch shank suits standard toolpost and turret pocket configurations on mid-size CNC and manual lathes.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the lathe spindle is fully stopped and the machine is in a locked-out, tagged-out state before mounting or removing the toolholder. Seat the shank fully into the turret pocket or toolpost and torque all clamping fasteners to the machine or toolpost manufacturer specifications. Verify insert seating and tool centerline height before initiating any cutting operation.
