Corner tool head T241TM — 90° turning head for APMT 1604 indexable inserts (Teknik Makina)

Corner tool head T241TM for turning and facing operations, designed to accept APMT 1604 indexable inserts and to fit tool posts with a 16 mm shank

• 90° cutting angle for precise turning
• Compatible with APMT 1604 inserts
• 16 mm shank for secure clamping
• Torx fixing M4x10 with T15 key

Consistent cutting geometry for repeatable results

The 90° cutting angle of this turning head delivers defined contact conditions between insert and workpiece, which helps to maintain a stable cutting line and predictable chip flow. Fitting APMT 1604 indexable inserts means the insert seating and rake geometry are standardised, so set-up times are reduced and tool life can be managed more reliably. The head’s compact form factor and standardised interface make it suitable for small to medium turning tasks in production and maintenance environments, where repeatability and setup speed are central to efficiency.

Secure mounting and quick insert changes

A 16 mm shank diameter provides a robust connection to the tool holder or turret, reducing vibration and improving surface finish when the assembly is correctly clamped. The insert is secured with a M4x10 Torx screw, accessed with a T15 key, enabling rapid insert replacement without special tooling. For workshop personnel unfamiliar with indexable tooling: the screw size defines the clamping torque range and the Torx drive reduces the risk of cam-out, which contributes to consistent clamping force and longer service life of the fastening elements.

Practical compatibility and application range

Engineered for use with APMT 1604 inserts from major suppliers such as Korloy, this head supports common grades used for steel, stainless steel and cast materials; selecting the correct insert grade and geometry will determine performance on specific materials. The tool head’s Ø40 mm footprint and 45 mm overall length keep clearance requirements modest while still providing four usable cutting edges per insert, which is economical for batch work. The recorded mass of 0.258 kg reflects a compact design that is easy to handle during tool changes and inventory management.

Why this holder suits a modern workshop

Using standardised insert formats and conventional fastenings simplifies procurement and stocking: a workshop can keep a small range of insert grades and rely on the same basic holder geometry across multiple machines. The combination of a clear 90° geometry, a 16 mm interface and Torx clamping delivers a balance of precision, serviceability and robustness — attributes that support throughput and reduce unexpected downtime. For process planners, this means fewer variables to adjust during set-up and more consistent part quality from the first piece.
