DRILLING VAPDSCB DRILLS 1) The above cutting conditions are for drilling 2xD hole depths without a pilot hole.
When drilling holes smaller than 1xD hole depths, it is possible to increase the RPM by 20%.
2) Drilling without a pilot hole is recommended.
If there is a pilot hole, the chips may not be broken. Use a peck feed when chip breaking is necessary.
3) For counter boring of a sloped face, a carbide end mill is recommended.
4) When machining austenitic stainless steels (X5CrNi1810), reduce the revolutions by 30 - 60% and reduce the feed rate by 40 - 60%.
5) Please use a collet type drill chuck.
6) Please reduce the revolution and feed rate depending on the drilling situation when the installation of workpiece or machine lacks rigidity.
7) Use sufficient cutting fluid.
The above mentioned cutting conditions are a guide when using water soluble cutting fluid.
Please reduce the revolution when using non-water soluble cutting fluid.
y Recommended Cutting Method
