With the INOSCREW modular milling system, the tool manufacturer InovaTools says it supports tool and mold construction with a technically sophisticated and cost-effective solution. Thanks to a large number of shank shapes and different geometries, the tool system covers a wide range of applications. Flexibility, precision and reduced set-up times are arguments designed to encourage the cutter to use the new InovaTools tool family.

In the INOSCREW modular tool system, the user can choose between cylindrical tool holders (short, long, extra long) as well as conical ones (short, long) with diameters ranging from 8mm to 20mm. A special trapezoidal inner thread ensures a secure hold in the replaceable head holder. The replaceable heads are fitted with a guide pin and a ground cone in addition to the trapezoidal outer thread. In combination with the contact surface, the milling replaceable head is seated very securely in the holder with no leeway after being screwed"

Sixteen head types ensure the necessary flexibility for a range of uses. Examples include the replaceable head STARMAX for HPC milling, the roughing end mill QUICKMAX, the finishing end mill MULTICUT, different copying, full radius and ball head end mills right up to deburring devices and quarter-circle end mills. All replaceable heads are made of quality hard metal and, whether coated or uncoated, thus feature good wear resistance and toughness. This means that high cutting speeds can be achieved with INOSCREW tools.

Thanks to its many unique design features, INOSCREW scores points with the outstanding stability of the tool system, and this successfully suppresses vibrations and oscillations. In practice, INOSCREW therefore wins people over thanks to its extremely high change and concentricity accuracy, which is below 20µm. Thanks to the precision inner thread and the guide pin, the replaceable heads can be changed quickly and easily directly on the machine. The replaceable head holder does not have to be removed for this purpose. This keeps set-up times extremely low.

Ditmar Ertel, Manager of InovaTools: "Thanks to this, it takes less than 1 minute to replace a head. This is Formula 1 speed compared to replacing a complete shank end mill, which involves removing the tool holder and making fine adjustments."
