Drilling tools \ Solid carbide high-performance deep-hole drill type UNI
process description, deep hole drilling
drilling the pilot bore hole
in order to get an accurate pitch, we recommend centring with our NC spotting drill no 11169.
for the pilot hole, we recommend our no. 11181.
these are 0.02 mm larger in diameter than the corresponding deep-hole drills and have a tip
angle of 140°.
the pilot hole should be at least 3xD in depth, to a maximum of 5xD.
entering the pilot bore hole with the deep hole drill
deep hole drilling up to 30xD
please enter the pilot hole at low rotation speed (n = 300 rpm) and a low feed rate
(Vf = 1000 mm/min), 1-2 mm before reaching the hole base, stop the feed. then increase the
rotation speed continuously until reaching the final speed. allow sufficient idling time to ensure
that the cooling pump has built up enough pressure.
deep hole drilling
carry out deep hole drilling with the recommended cutting values, do not remove chips.
for cross-drilled holes or exiting, reduce the feed by 50 %.
extending the deep hole drill
retract the deep hole drill by about 1-2 mm from the base of the hole
reduce the rotation speed to (n = 300 rpm) and travel out of the hole with a low feed rate of
(Vf = 1000 mm/min). Cooling must be switched off during this process.
