Hertel 113017437 MGTN-4 Carbide Cutoff Insert 4mm

Product Description

The HERTEL 113017437 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured to the MGTN-4 insert style, it features a 4 mm (0.1600 inch) cutting width and a neutral lead angle, making it well-suited for straight plunge cutting with balanced cutting forces. The insert is produced in HERTEL grade HC335 with a multilayer TiC/TiCN/TiN coating, delivering wear resistance and surface finish quality across a range of workpiece materials. A 30-degree relief angle reduces rubbing on the part face. This insert is installed by machinists and CNC operators in production and job-shop environments.

This insert is intended for cut-off and parting applications in ferrous and non-ferrous machining. The HC335 grade and multilayer coating are suited for material grades C5 and C6, covering a broad range of steels and cast irons under moderate to high cutting speeds. Typical use is in production turning where consistent groove width and clean part separation are required. The neutral lead angle suits center-line plunge cuts without side load bias.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine before seating or removing the insert. Use the correct torque wrench and manufacturer-specified clamp screw to secure the insert — do not overtighten by hand. Inspect the insert seat and clamping components for chips or debris before seating a new insert to ensure proper support and alignment.
