Corner tool holder T493TM — for LNGX 1307 indexable inserts, 90° cutting angle (Teknik Makina)

A robust corner turning head designed for external turning and facing tasks, the corner tool holder T493TM suits workshops requiring repeatable, precise 90° corner cuts with LNGX 1307 indexable inserts

• 90° cutting geometry for precise corner turning
• Compatible with LNGX 1307 indexable inserts
• 27 mm shank diameter for secure clamping
• M4x10 Torx screw; T15 Torx key required

Consistent, accurate corner turning from the 90° geometry

The central advantage of this tool is its 90° cutting angle, which delivers predictable corner profiles and simplifies toolpath planning on lathes or turning centres. Fitted for LNGX 1307 indexable inserts, the holder supports efficient chip removal and repeatable seating, with seven cutting edges providing multiple index positions before replacement is required. This arrangement reduces non-productive time and improves process reliability, while the defined geometry aids programmers and operators in achieving consistent part geometry across production runs.

Fast, secure mounting that keeps set-up time low

A 27 mm shank provides a stiff interface to the turret or toolpost, reducing chatter and keeping tolerances tight during interrupted cuts. The insert is clamped using an M4x10 Torx screw, released and tightened with a T15 key, allowing quick insert changes and straightforward torque application with standard maintenance tools. These features combine to shorten machine downtime and deliver a dependable clamping solution that supports predictable tool life and surface finish.

Broad system compatibility for flexible tooling strategies

Compatibility with LNGX 1307 indexable inserts and proven fitment for Walter insert systems makes the holder a practical choice when consolidating tooling inventories or switching between supplier inserts. The acceptance of established insert formats means straightforward integration into existing tooling families, enabling shops to standardise on a small number of holders while retaining a wide range of cutting grades and geometries from different insert manufacturers.

Durable dimensions engineered for workshop conditions

With an 80 mm diameter head and 50 mm overall length, the toolholder balances reach and rigidity for many external turning tasks; the unit weight of 1.124 kg provides mass that dampens vibration without excessive bulk. The construction and geometry aim to withstand the rigours of daily workshop use, supporting stable cutting conditions and contributing to consistent surface quality and dimensional control on finished parts.

FAQ

What insert type does this holder accept?
The holder is designed for LNGX 1307 indexable inserts and is compatible with systems from Walter, enabling use of standard insert grades.

Which fastener is used to secure the insert?
An M4x10 Torx screw secures the insert; a T15 Torx key is recommended for correct tightening and release.

What shank diameter is required for mounting?
The tool has a 27 mm shank diameter, which fits turrets and toolposts designed for that shaft size and offers increased rigidity.

Is the T493TM suitable for heavy-duty cuts?
The combination of a substantial head (Ø 80 mm) and 27 mm shank provides good stiffness for many external turning operations; select cutting data and insert grade according to workpiece material and depth of cut.

How does the holder improve uptime?
By accepting widely used LNGX 1307 inserts and using a simple M4x10/T15 clamping method, the holder reduces insert-change time and supports predictable tool life, helping to maintain steady production.
