Parting clamp holder MGM 300 L125mm — left-hand, 20 mm clamping width (Teknik Makina)

The Parting clamp holder MGM 300 L125mm is a left-hand grooving and parting toolholder designed for indexable insert systems and precision lathe operations

• Left-hand cutting orientation
• 125 mm overall length
• 20 mm clamping width
• Compatible with Korloy MGM 300 inserts

Engineered for accurate grooving and reliable parting

The holder is built to convert insert geometry into consistent cut quality: the 20 mm clamping width and ISO 2020 designation ensure secure seating of the indexable insert, while the left-hand orientation supports dedicated machining strategies. With a max grooving depth of 28 mm and a 3 mm cutting width, the design reduces lateral vibration and enables repeatable cuts across production runs. For workshops moving from provisional setups to standardised processes, this holder provides measurable improvements in tool life and surface finish by stabilising the insert under load.

Robust clamping and simple serviceability for production environments

Fast, reproducible clamping is achieved via the M5x20 clamping screw, which requires a 4 mm Allen key for adjustment. The holder’s 20 × 20 mm head dimensions and 125 mm overall length create a compact profile that still resists bending moments typical in grooving tasks. Maintenance is straightforward: replacement of the indexable insert family is quick when worn, lowering machine downtime and improving throughput. These mechanical choices translate directly into reduced setup variance and higher first-pass yield on batch work.

Seamless integration with common insert systems and machine shops

Designed for the widely used MGM 300 indexable inserts (Korloy), the toolholder fits established tooling families, cutting inventory complexity. The left-hand cutting configuration suits operations that require counter-directional parting or specific chip flow management. Supplied by Teknik Makina and distributed via Metav Werkzeuge, the holder aligns with industry workflows, making it simple to adopt in manual or CNC lathe setups where predictable performance and compatibility are priorities.
