Make a pilot hole.
To use FTO-GDXL for 30 times the drill diameter, please contact our sales. 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. FS-GDS, FS-GDN, FT-GDS, FT-GDN : See page 4451 The sizes for guide holes are available. Insert the FTO-GDXL/FTO-M-GDXL/FTO-H-GDXL into a pilot hole with zero or low revolution. Increase the revolution to the designated speed and start drilling. When working on a curved surface, use the FX-ZDS (end mill for counterboring) to counterbore a pilot hole. 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.
To use CAO-GDXL for 30D times the drill diameter, please contact our sales. Make a pilot hole. For a pilot hole, select same size or 0.020.05mm larger size drill than CAO-GDXL. The recommended drills for a pilot hole are listed below. FTO-GDS FTO-GDN FTO-PLT Insert the CAO-GDXL into a pilot hole withzero or low revolution. Increase the revolution to the designated speed and start drilling. After drilling, move the drill away from the bottom of the hole; then reduce its speed while pulling it out of the hole.

Centering by OSG s starting drills Use 120 or 130 degree point angle starting drills.recommended drills: NC-LDS, TIN-NC-LDS Make a pilot hole. Recommended drill : EX-GDS For a pilot hole, select 0.05mm to 0.1mm larger size drill than TDXL. For deep hole, we recommend to drill deeper pilot hole. For a vertical machining center. When drilling many holes in a small area with vertical machining center. We recommend only centering by 130 degree point angle LDS to avoid chips building up in pilot holes, which can cause drill chipping or breakage. When drilling the pilot hole it is recommended to make the hole 3xD in depth, at a feed rate equal to (Drill x 0.01) per revolution. Straightness will be less accurate than a comparable operation in a horizontal machining center. Start supplying the coolant. Increase the revolution to the designated speed and start drilling. At the start of drilling, set the feed rate to 1% of the drill diameter and increase the feed rate when the depth reaches between 3xD and 5xD. We recommended to use point angle from 120 degree and over. Increase feed rate to between 1 and 2% Set it to 1%D between 3xD and 5xD Insert the TDXL into a pilot hole with low revolution. (500min After drilling, move the drill away from the bottom of the hole; then reduce its speed while pulling it out of the hole.
