Make a pilot hole.
For a pilot hole, select same size or below 0.1mm larger size drill than FTO-GDXL/FTO-M-GDXL/FTO-H-GDXL.
The recommended drills for a pilot hole are listed below.
Increase the revolution to the designated speed and start drilling. Insert the FTO-GDXL/FTO-M-GDXL/FTO-H-GDXL into a pilot hole with zero or low revolution.
After drilling, move the drill away from the bottom of the hole; then reduce its speed while pulling it out of the hole.
Make sure to use an internal coolant supply when drilling.
When working on a curved surface, use the FX-ZDS (end mill for counterboring) to counterbore a pilot hole.

The sizes for guide holes are available.
To use CAO-GDXL for 30D times the drill diameter, please contact our sales.
