Unlike other thread mills, the AT-2 has a left-hand blade, but why? Does the left-hand blade differ from other tools?
The AT-2, a thread mill with end cutting edge for high-hardness steel, is a left-hand blade specification (= used with left-hand rotation of the tool).
(Tool left rotation + climb cut ).
Relationship between AT-2 usage and tool specifications
The AT-2 is a thread mill that performs pilot hole drilling and threading at the same time.
Other thread mills are drilled in advance before machining, but the AT-2 can be threaded from muku.
* Since the pilot hole is drilled at the same time, the machining movement is from top to bottom.
(Tool Right Rotation + Up Cut) or (Tool Left Rotation + climb cut )

* Since the pilot hole is drilled at the same time, the machining movement is from top to bottom.
(Tool Right Rotation + Up Cut) or (Tool Left Rotation + climb cut )
* climb cut recommended to enable harsh high-hardness machining.
In order to meet this at the same time, the AT-2 will have a left-handed blade.
