Tangential indexable insert milling cutters for maximum tooth utilisation

MaxiMill – Tangent delivers turbo feed rates

We've all been there. You've got a component to machine, but can't what you're doing because of all the interfering contours. Face milling cutters are out of the question, not least when long overhang lengths render stable, low-vibration machining impossible. The situation may sound hopeless, but in fact all you need is the right tool: the new MaxiMill – Tangent. This tangential indexable insert cutter shows its true strengths when machining steel and cast iron components.

Go straight to the milling system

Machining difficult to access steel or cast iron components is often a challenge, especially in unstable roughing applications.

With the MaxiMill – Tangent, you can achieve stable, low-vibration high-performance milling with turbo feed rates and maximum stability of the indexable insert in day-to-day operations.

MaxiMill – Tangent: Advantages / benefits

Stable, soft-cutting system
Rugged design permits up to 50% greater feed rate per tooth
Wide variety of tool holders with different connections: G (thread) / A (shell mill adapter) / C (cylindrical shank)
Maximum number of teeth on the milling body thanks to tangential clamping
The best axial and concentric run-out properties due to precision-ground inserts and tight manufacturing tolerances for the tool holder
Reduced vibration thanks to irregular tooth pitch
Unbeatable accessibility allows for rapid tool change

The MaxiMill – Tangent enables stable and yet soft-cutting machining. We have prioritised a uniform chamfer profile across the entire cutting edge length of the precision-ground indexable inserts. With a wide range of holders and inserts with four usable cutting edges in sizes -09 and -13, we offer a versatile selection for different applications. Furthermore, we have an integrated face-cutting edge, which offers numerous advantages, including uniform material removal that results in a smoother component surface. In addition, the cutting forces are distributed more evenly, which reduces the load on both the tool and the machine.

We are launching the MaxiMill – Tangent in three holder variants: as a face mill, a screw-in cutter and with a cylindrical shank, and in sizes ranging from 25 mm to 125 mm. The large and stable contact surfaces for the indexable insert integrated into the holder provide additional stability and reliability. But the advantages of tangential clamping don't stop there. Compared to radial systems, tangential clamping provides extra space for significantly more indexable inserts on the milling cutter body, thus guaranteeing maximum cutting-edge density and efficiency. And to prevent any drop-offs in efficiency during tool changes, inserts can be rotated, turned and replaced quickly and easily.

With internal coolant holes to prevent chip jamming

One key to the MaxiMill – Tangent's success lies in its optimum chip control for shoulder, corner and face milling – something attributed to both its overall design and its internal coolant holes. These prevent disastrous chip jams, improve the surface quality of the component and significantly extend the service life of the tools.

Actively vibration-damped transverse slot shell mill adapter: vibrations effectively minimised

The MaxiMill – Tangent is also compatible with our actively vibration-damped transverse slot shell mill adapter.

This combination also delivers maximum process security when working with components that are difficult to access or with troublesome interfering contours.

To the adapter

Do you have to machine workpieces with long overhangs and experience problems with strong vibrations? With our actively vibration-damped transverse slot shell mill adapter including mounted Densimet core, vibrations can be kept to a minimum, thereby increasing the tool life and significantly improving surface quality.
