Hitachi Tools is listed on the drill for machining cast iron for MQL processing

February 17, 2023

Hitachi Tools has launched the ultra-hard drill bit for cast iron machining "Super Hard OH Non Step Borer for cast iron". In addition to ordinary cast iron, it is also used for punching of high-strength cast iron parts such as compacted graphite iron and ductile iron. The price is 12,300 to 870,500 yen (including tax).
According to the company, as the weight of automotive components is reduced, the strength of component materials continues to increase. In addition, in order to reduce the environmental load, semi-dry processing such as MQL (Minimum Quantity Lubrication) processing with a small amount of cutting oil is spreading. For these reasons, there are more and more cases where tools need to be used at high cutting temperatures, so the company developed this bit with high wear resistance and oxidation resistance.
The new drill reduces wear by using a concave blade design and improved corner shape. The base material uses "TH Coat" which is high in hardness and excellent in oxidation resistance. Even if the cutting temperature is high, it can last longer than the original product because it can maintain high wear resistance. In addition, by improving the shape of the blade groove, it is easy to discharge the chips, and even the deep hole processing can work stably.
For example, in the case of semi-dry machining of ductile iron (FCD700) using a drill having a tool diameter of 6.0 mm, the original number of holes can be processed twice at a cutting speed of 120 m/min. Deep holes with a maximum L/D (machining depth / machined diameter) of 30 can be machined. When the FCD450 is machined at a drill speed of 4000 mm/min using a drill having a diameter of 5.0 mm, a small hole having an L/D of 20 can be drilled in 1.5 seconds.
