1. Guide Drilling should be done as Diameter+0.1mm
between 3×D and 5×D
2. For Main Drilling, proceed with low RPM at Guide
Drilling segment.
(RPM 300, FEED 400mm/min)
3. Just before the end of Guide Drilling segment, reduce
feed to zero and increase the RPM according to
Recommended
4. After then, proceed main drilling by increasing feed
without step drilling.
5. When coming out from Guide Drilling start point after
drilling, RPM should be reduced as 300 and feed
should be 1000 mm/min.
6. When coming out from Guide Drilling segment to the
outside, the feed should be decreased as 50%

Recommended tapping speeds and cutting fluids
Recommended tapping speeds and cutting fluids
Tapping speeds depend on very important factors such as material type of tap, chamfer length, drill size,
work materials and cutting fluids.
Users need to check every aspect before applying it.
Morever, cutting fluids, cooling and abrasion resistance are three important factors affecting cutting fluids.
Therefore, users should provide enough fluids during the tapping process.
