This is a drill with a flat tip, and the ADF and ADFO series are applicable.
A flat tip shape is one in which the point angle of the drill is 180 degrees and has a flat shape.
It has advantages in machining that is difficult to process with a drill with point angle .
This is because in inclined surface and curved surface machining, point angle can cause the drill to shift.
The flat tip shape suppresses the radial load of the drill from shifting.
This is not the only advantage of the flat tip shape.
The fact that the load on the drill is less likely to be applied in the radial direction also applies to the workpiece.
The fact that the workpiece is less likely to be subjected to radial load is also effective in suppressing burrs in thin plate processing.
In addition, flat drills can be used in a variety of applications.
・ counterboring Machining
・Guide hole processing for deep holes
・Stop Tap Pilot hole processing
・Cross hole processing
・Plunge processing
etc
Of course, it can also be used for normal drilling. In particular, it is a drill that leads to a reduction in machining costs in a variety of applications that require pre-processing.
