HSS burr set

Cut 3 has chip breakers and is especially well-suited to machining of steel, cast steel and cast iron. It is used in a rotational speed range of 1,200 to 7,900 RPM, depending on the burr diameter. Set 86 Z3 contains three HSS rotary cutters for fine and coarse stock removal in the most common shapes and dimensions. The sturdy plastic box protects the tools from dirt and damage.
