Hertel 113016909 MGTN-3 HT10 Carbide Cutoff Insert 3mm

Product Description

The HERTEL 113016909 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured in the MGTN insert style with a size code of 3, it delivers a 3 mm (0.1200 inches) cutting width with a neutral lead angle and a 30-degree relief angle. The HT10 grade, uncoated solid carbide construction is suited for consistent chip control and dimensional accuracy in cut-off applications. Licensed machinists and CNC operators install this insert as a direct replacement in compatible MGTN-style toolholders.

This insert is intended for cut-off and parting operations in production turning environments, both job shop and manufacturing floor settings. The neutral lead angle suits straight plunge parting cuts without lateral cutting forces, making it a reliable choice for bar-fed turning applications where clean part separation and repeatable width are critical. Material grade C2 positions it for use on cast iron and non-ferrous materials.

Key Features

• MGTN insert style with size code 3 for compatibility with standard MGTN parting toolholders
• 3 mm (0.1200 inches) cutting width for precise parting and grooving
• Solid carbide construction, HT10 grade, for rigidity and wear resistance
• Neutral lead angle (0 degrees) for straight plunge cut-off without lateral cutting force
• 30-degree relief angle to reduce rubbing and extend edge life
• Uncoated finish — material grade C2, suitable for cast iron and non-ferrous workpieces

Compatibility

Designed as an OEM-style replacement insert for MGTN-style parting and cut-off toolholders accepting a size 3 insert with a 3 mm cutting width.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before changing inserts. Seat the insert fully and evenly in the toolholder pocket and secure the clamping screw to the toolholder manufacturer's specified torque using calibrated tooling — do not overtighten, as carbide inserts are brittle and can fracture under uneven clamping load. Inspect the pocket and clamping components for wear or debris before installing a fresh insert.
