Recommended Drilling Procedure for Deep Hole Drilling
1 Drill a pilot hole 1-2xD deep with a short drill. The pilot drill should be
0.03-0.05 mm larger than the long drill and its point angle should 1
also be larger (over 135°).
2 Enter the pre-hole using low feed and rotate at low speed 2
(50-100 RPM) until it engages the material.
3 Activate the coolant system and increase rotation speed to the
recommended cutting parameter, maintain for 2-3 seconds, then 3
continue at recommended drilling feed. No pecking is required.
4 After having reached the required depth, reduce speed to 4
50-100 RPM before retracting from the hole.

- 40xD & 50xD must utilize a 20xD intermediary drill along with pilot drill.
- In through holes, the tool exit should not exceed 2-3 mm.
