3.2 SOLIDTHREAD – Solid Carbide Endmills
THREAD MILLING ISCAR offers a rich line of solid carbide endmills for thread milling operations. These tools,

with nominal diameters from 0.72 mm to 20 mm by metric system or from 0.045 inch to
0.75 inch by imperial and United States customary systems and varied in form, are intended
for machining all types of materials such as: steel, stainless steel, cast iron, etc.
The tools differ in cutting geometry, helix angle, number of flutes, length and grades.
ISCAR catalogs and leaflets contain detailed guidelines for using the solid carbide endmills
in thread milling. Commonly, tool selection and cutting data depend on application
requirements and workpiece material.

Cutting tool manufacturers, from small shops to world-known companies, produce solid
carbide endmills of the same sizes that often seem like copies of each other.
However, despite a formal resemblance, there is a great difference in performance and
tool life of the cutters. The reason lies in carbide grades, grinding technology and cutting
geometry features.
