Description
Version:
Long flutes, left-hand helix.
Extremely irregular spacing (EU) from size 2.
This ensures that the reamed bore is absolutely round and free from chatter marks.
Extremely irregular spacing (EU) from size 2.
This ensures that the reamed bore is absolutely round and free from chatter marks.
Application:
On stable, low vibration machines. Longer tool life and better dimensional accuracy than HSS reamers.
Tool material:
Sizes 1 − 13 solid carbide.
Sizes 14 − 16 with carbide inserts, supported by hard nitrided steel guide chamfers.
