Kennametal 1085675 Modular Lathe Shank KM50 Neutral

Product Description

The KENNAMETAL 1085675 is a neutral-cutting modular lathe shank designed for use with KM50 quick-change tooling systems on CNC turning centers and manual lathes. Built to the NCM-SS Round Shank Standard Length series, this shank provides a rigid, repeatable interface between the machine turret and cutting head. It features a 2-inch (50.80 mm) round shank diameter, an overall length of 5.59 inches, and a shank length of 4.34 inches. Through-coolant capability is built in, supporting high-pressure coolant delivery directly to the cutting zone. At 4.89 pounds, it is machined to tight tolerances for reliable seating and minimal runout in production turning applications.

This shank is intended for turning operations requiring a neutral tool orientation, meaning the cutting head is positioned on centerline without left or right offset. It fits KM50-compatible turret pockets and is well suited to medium-duty turning on horizontal CNC lathes in job shop and production environments. Machinists and CNC operators installing or rebuilding tooling assemblies will find this shank appropriate for both roughing and finishing pass setups where coolant-through tooling is preferred.

Key Features

• KM50 connection size for quick-change, high-repeatability tooling interface
• Neutral cutting direction — centerline alignment for standard OD turning
• Through-coolant capability for improved chip evacuation and tool life
• 2-inch shank diameter (50.80 mm) with 4.34-inch shank length
• 5.59-inch overall length suits standard-reach turning applications
• NCM-SS Round Shank Standard Length series construction

Compatibility

Designed as an OEM-style modular component for KM50 quick-change tooling systems used on CNC turning centers equipped with KM50-compatible turret interfaces.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle and turret before mounting or removing any tooling components. Ensure the KM50 receiver and shank mating surfaces are clean and free of chips or debris before seating. Consult the machine tool manufacturer's documentation and applicable shop safety procedures for proper clamping torque and coolant connection requirements.
