Turning Tools for Internal Machining

Dieterle offers three turning tool systems for internal machining. Depending on the application, they provide maximum flexibility for internal processing starting from a diameter of 0.7 mm.

MINIFIX System

Great, simple clamping system with V-groove fixation for precise adjustment of the tip height and excellent interchangeability accuracy at small diameters.

INO-CUT System

Bore processing from Ø 7.8 mm, especially for punching grooves, free cuts or profile inner cuts, as well as for threading.

Boring Bars

Internal machining with ISO inserts in the smallest ranges

MINIFIX – Turning tools for internal machining

Our MINIFIX turning tool system stands for the highest precision and efficiency in internal machining. Designed for workpieces where maximum accuracy and cost-effectiveness are crucial at small diameters. The MINIFIX system offers flexible solutions for internal turning as well as many other demanding machining tasks.

Features of the MINIFIX system

The MINIFIX system impresses with its versatility and flexibility. The specially developed holder for internal machining allows for quick and precise tool changes. With this internal turning system, even complex machining tasks from a diameter of 0.7 mm can be performed accurately and burr-free.

Overview of applications:

Drilling out holes – internal turning forward and backward: Perfect results when machining the smallest holes and internal contours.
Precise parting and burr-free back turning: Special cutting geometries enable burr-free machining even in hard-to-reach areas.
Axial spot drilling or turning: For demanding applications in the axial range.
Thread chasing: Efficient internal thread machining with the highest precision.
Internally cooled holders: Thanks to the internal coolant supply, tool life is extended and machining quality is improved.

Advantages of indexable inserts and precision holders

The MINIFIX system relies on high-quality indexable inserts that ensure long tool life and easy, quick handling. Combined with internally cooled holders, the cooling of the cutting edges is optimized—even under high demands.

Your benefits at a glance:

High precision: Perfect results even at the smallest bore diameters.
Cost-effectiveness: Durable tools and simple handling reduce downtime and setup times.
Flexibility: One tool for a variety of applications, e.g., drilling out holes, parting, or reverse turning.

Application areas

The MINIFIX system is ideal for manufacturing precision parts in industries such as automotive, medical technology, watchmaking, aerospace, defense, fluid technology, and many other fields where tight tolerances and high surface quality are required.

Why choose Dieterle special tools?

For decades, the name Dieterle has stood for innovation and quality in cutting technology. With the MINIFIX system, we offer you a tool specifically developed for the demands of modern internal machining—maximizing efficiency and precision.

High-Quality Turning Tools for Internal and Bore Machining – INO-CUT

Discover our innovative turning tools for precise internal machining, bore machining, parting, NC fine turning, full radius turning, internal turning, profiling, internal undercuts, axial grooving, back turning, pre-grooving, chamfering, and threading – including metric threads (partial and full profile), Whitworth full profile, and trapezoidal threads.

With easily replaceable inserts, internally cooled tool holders, and finely tuned coating materials, INO-CUT offers a robust solution for long tool life and maximum precision in bore machining. Our turning tools are specifically designed for demanding internal machining applications, ensuring efficient, stable, and precise results.

Benefits of our internal turning tools:

Turning tools for parting, NC fine turning, and full-radius turning
Inserts for internal turning, profiling, and internal undercuts
Precision axial grooving, back turning, and pre-grooving
Chamfering and threading (metric threads, partial profile, full profile, Whitworth full profile, and trapezoidal threads)

Our standard inserts are available starting from a diameter of 7.8 mm and are ideally suited for internal machining on lathes. As special tools, we offer profiled tools within the INO-CUT system, which make your production even more precise, stable, and efficient.

High-Quality Tool Holders for Turning Tools

Our internally cooled precision tool holders made from steel and carbide ensure high repeatability during tool changes. Both types of holders are compatible with a standardized interface, allowing inserts in matching sizes to be used. Carbide holders offer greater flexibility in cutting depths, while steel holders provide a cost-effective alternative for shallower cuts.

Application Areas of INO-CUT Turning Tools:

From Ø 7.8 mm, particularly for grooving, internal profile grooves, undercuts, and threading. Perfect for internal machining, bore machining, parting, NC-profiling, full radius turning, internal turning, profiling, internal undercuts, axial grooving, back turning, pre-grooving, chamfering, and threading (metric ISO, trapezoidal, and Whitworth threads).
