answer

Since it is a left-hand blade specification, please use it with reverse spindle rotation & climb cut .

 
Please confirm in advance that the bottom of the finished hole with end cutting edge is permissible in the machining instructions because it has a different shape from a normal drill.

The bottom shape of the finished hole is as shown in the figure below. Please confirm in advance that it is acceptable.
