Corner tool head — 40 mm, internal coolant, for APMT 0903 indexable inserts (Teknik Makina)

The corner tool head is a coolant-fed indexable insert holder designed for square-shoulder turning and compact tool setups, compatible with APMT 0903 indexable inserts and optimised for repeatable shoulder and face operations.

• 40 mm diameter for compact installations
• Internal coolant for improved chip evacuation
• Compatible with APMT 0903 Korloy inserts
• 90° cutting angle for square-shoulder machining

Accurate square shoulders with compact geometry

The holder’s compact 40 mm diameter and precisely maintained 90° cutting angle translate into consistent shoulder dimensions and reduced manual rework on repeat production runs. The design supports stable insert seating, which limits vibration and enhances surface finish; this predictable geometry is particularly beneficial when tight tolerances matter and when set-up times should be minimised. The combination of compact form and rigid construction enables efficient use on multi-tool turrets and small-lathe configurations without sacrificing repeatability.

Coolant-fed design for extended tool life and cleaner cuts

An integrated internal coolant channel directs cooling and lubrication precisely to the cutting edge, lowering thermal load and aiding chip control during interrupted cuts. This focused coolant supply reduces flank wear and helps preserve insert geometry, extending service intervals and cutting costs per component. For operations that demand controlled chip evacuation—especially in shoulder and face turning—the coolant-fed approach improves machining stability and supports more consistent cycle times under moderate to high cutting parameters.

Compatibility that simplifies tooling logistics

This indexable insert holder accepts APMT 0903 inserts and is compatible with Korloy-manufactured grades, easing stock management where those inserts are already in use. Fast replacement is ensured via the supplied Torx fastening system (Torx key T8; screw M2.5x5.5), allowing quick insert changes and minimising machine downtime. The unit’s compact overall length and standard interface simplify integration into existing tool stations, while the proven fastening specification supports secure clamping through repeated changeovers.

Production-ready build for reliable operation

Engineered by Teknik Makina with a focus on workshop durability, the holder’s lightweight yet robust construction (approx. 0.248 kg) and 40 mm overall length make it suitable for high-mix, space-constrained production environments. The design reduces inertia on the turret, improving acceleration and deceleration in CNC sequences and helping to maintain part accuracy across long runs. Clear interchangeability with APMT 0903 indexable inserts supports flexible process planning and rapid response to changing production demands.
