ROUNDNESS

One of the most remarkable features when drilling with this tool is the roundness of the hole produced.

The three flutes guide the tool during the drilling process and have the function of self-centering.The results are excellent in terms of circularity, even after more than 3,000 holes!

The positioning accuracy is in the order of 4 µm, well worth mentioning without centering!

BURR

During tests performed on our 3-axis machine, we found that the burr formation was extremely low both at the entry and exit of the hole.

The comparison with a standard drill and a competitor tool for titanium shows that the tip and cutting angle of the 3-lip drill ensure ideal penetration into the material. Burrs of 4 µm at the entrance and 15 µm at the exit were measured.

CHIP

The specially designed geometry for chip removal focuses on two specific elements:

1) The tip and the sharpening of the drill enable an optimized penetration into the material. This limits the temperature rise, which prevents premature wear of the tool.

2) The particularly low helix angle and the low roughness in the chip flutes allow the chips to be removed quickly. Furthermore, overheating of the tool is reduced.
