Kennametal 1144829 Modular Lathe Shank KM40 Neutral

Product Description

The KENNAMETAL 1144829 is a modular lathe shank designed for turning applications on CNC and manual lathes. It uses a KM40 quick-change connection, allowing the shank to mate with compatible KM40 tooling heads for fast, repeatable tool changes. The cutting direction is neutral, making it suitable for straight turning operations. The shank measures 1.5 inches (1-1/2 inch) in diameter, with an overall length of 4.33 inches and a shank length of 3.33 inches. Through-coolant capability is built in, supporting directed coolant delivery to the cutting zone to extend tool life and manage chip evacuation in deep or continuous cuts.

This shank is used in production turning environments where modular tooling systems reduce changeover time and maintain tight runout tolerances. It fits horizontal and vertical turning centers equipped with KM40-compatible tool blocks or turret stations. The NCM-SS Round Shank Standard Length series is commonly applied in general-purpose OD turning on both ferrous and non-ferrous workpieces. Licensed machinists and CNC tool-setting technicians are the primary installers in job shop and production settings.

Key Features

• KM40 modular connection for fast, repeatable head changes with consistent tool offset retention
• Neutral cutting direction suits straight turning without axial tool pressure bias
• Through-coolant capable for directed coolant delivery at the cutting edge
• 1.5-inch round shank diameter fits standard KM40-series turret and block holders
• 4.33-inch overall length with 3.33-inch shank length for rigid overhang control
• NCM-SS Round Shank Standard Length series for broad compatibility across KM40 platforms

Compatibility

Designed for use with KM40 modular tooling systems. Compatible with turret stations, block holders, and quick-change units built to the KM40 connection standard. Consult the KENNAMETAL NCM-SS series documentation for specific head and adapter pairings.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle and turret before installing or removing the shank. Verify the KM40 mating surfaces are clean and free of chips or burrs before seating the connection. Confirm through-coolant passages are clear and the coolant supply port aligns with the machine tool block before final clamping.
