Corner tool head T258TM – indexable insert holder for APMT 11T3, 32 mm shank (Teknik Makina)

A compact Corner tool head T258TM for secure mounting of APMT 11T3 indexable inserts, engineered to support precise corner and facing operations in general workshop and light industrial milling setups.

• Corner tool head T258TM by Teknik Makina
• Compatible with APMT 11T3 inserts (Korloy)
• 32 mm shank diameter for secure clamping
• 90° cutting angle, overall length 63 mm

Stable geometry for repeatable precision

The holder is built around a 32 mm shank and a 100 mm head diameter to provide a stable interface with standard tool posts and turret adaptors. That greater mass and contact area reduce vibration and support repeatable accuracy during each pass, which in practical terms means fewer rejects and less rework. The unit’s weight of 1.81 kg contributes to damping of high-frequency chatter, improving surface finish without additional balancing. Where setup time is at a premium, a stable tool head cuts cycle variability and helps achieve consistent component quality.

Fast insert changes and clear compatibility

Designed specifically for APMT 11T3 format inserts and compatible with Korloy insert grades, the head features a Torx retention system (Torx screw M2.5x5.5, Torx key T8) for reliable clamping and quick changeover. Indexable inserts allow the cutting edge to be rotated or replaced without altering tool geometry, which conserves machine setup and reduces tooling costs over time. The Torx fixing provides a secure seat to maintain cutting orientation and repeatability, and the clear specification of the retention parts simplifies spare-part sourcing for maintenance planning.

Practical integration and machining benefits

With a 90° cutting angle and 63 mm overall length, the head is suited to facing and shoulder operations where a square approach is required. The design supports standardised toolholder bores and fixtures, so the holder integrates into existing tooling systems with minimal adaptation. The combination of robust clamping, standardised insert format and compact footprint reduces downtime during tool changes and streamlines workshop logistics. For production environments focused on throughput and surface quality, the head offers a pragmatic balance of rigidity and serviceability.

FAQ

What insert type fits this tool head?
The Corner tool head T258TM accepts APMT 11T3 indexable inserts; compatible insert grades from Korloy are indicated in the technical data and can be used according to the intended machining task.

How is the insert secured to the head?
Insert retention is by a Torx screw specified as M2.5x5.5; the Torx key required for tightening and loosening is size T8, providing a secure and repeatable clamping force.

Which machines or holders is the head suited for?
The head is configured with a 32 mm shank, making it suitable for tool posts and adaptors designed for that shank diameter; compatibility should be checked against the machine’s toolholder bore and clamping scheme.

Does the head support heavy-duty roughing?
The robust construction and mass (1.81 kg) give good damping characteristics; for heavy-duty roughing it is necessary to match the insert geometry and grade to the application, using the APMT 11T3-compatible inserts specified.

What are the primary benefits of using this head in production?
Using the Corner tool head T258TM reduces setup time through standardised insert mounting, improves stability with its 32 mm shank and head mass, and supports consistent surface quality via the 90° cutting angle.
