effective up to full 1xD axial depth. Side milling (profiling) is effective
up to 0.5xD radial by 1.0xD axial depth.
Ÿ Shank tolerances to h6.
Ÿ Reinforced corner by extra positive dubbing for long tool life.
Ÿ Centre cutting with drilling possibility.
Ÿ Designed to works standard over the 1mm to 20mm diameter range.
Ÿ Multiple corner radii and extended neck configurations are available to
maximise metal removal rates.
Sub-micron carbide grade of European origin.

CODE
The current market trend is towards the increasing use of aluminium substrate in
the manufacture of die cut and moulds. Aluminium substrate offers many
advantages, such as excellent machinability and good thermal conductivity, as well
as being light in weight, with a high strength-to-weight ratio.
Due to the relative softness of aluminium, specific characteristics and geometries
in solid carbide end mills are required for efficient machining of this ductile
material.
Somta's high efficiency carbide end mill range with optimal flute geometry
provides all the required features for high performance machining of aluminium,
with the added benefits of greater stock removal rates at high speeds and feeds,
excellent surface finish quality and extended tool life.
The range allows for roughing and finishing applications in aluminium and other
non-ferrous materials and competes favourably with current global state-of-the-art
solid carbide cutting tool designs.
Somta has integrated a state of the art Walter Helicheck
Basic 3 into its quality check management process. The
Walter Helicheck is a 4-axis CNC measuring machine
for non-contact complete measurement of rotationally
symmetrical precision tools with complex geometry.
