Hitachi Tools Introduces the Giant Threaded Tool for Super Hard Alloy Taps

“Hitachi Tools finds out the cause of blade wear and adopts a series of policies to improve durability. Superhard alloys are less than half the processing time compared to high-speed steel, and can also be used for thread cutting of high-hardness materials.”
In the spring of 2009, Hitachi Tools will introduce super-hard taps (manufactured with a male threaded tool).
The development of the product is almost at the end, and the tests conducted by the group companies at Hitachi Manufacturing also show good results. From the main products such as end mills and drills to taps that can be threaded in the screw holes, Hitachi is constantly developing its product range and seeking benefits.
Since the tap has always attached great importance to the wear resistance (toughness) of the blade, and the superhard alloy lacks toughness, it has not been used in the production of the tap. The mainstream has always been a high-toughness high-speed steel product. Hitachi Tools identified the causes of blade wear and adopted a series of policies to increase durability. Compared with high-speed steel, super-hard alloys can process less than half of the time, and can also be used for thread cutting of high-hardness materials.
Hitachi temporarily named it "Epoch Power tip", which is now in the stage of productization discussion, and the price is scheduled to be similar to other competing companies. For the stable processing of taps, unique technology is indispensable, including the setting of cutting conditions. Therefore, no other new companies have been added. At present, the market share of taps is accounted for by more than half of OSG and the Manchu and Production Center (Central District of Tokyo).
