Thread tools \ Technical introduction – thread milling

Internal cooling during thread milling

Internal cooling is of particular importance when it comes to thread milling. The short chips must be rinsed
out of the working area by the coolant medium. Otherwise, the chips produced could damage the surface of
the thread or even cause cavities on the tool.
We make a fundamental distinction between thread milling cutters with axial coolant fl ow, used for blind Thread milling cutters with axial coolant fl ow
holes, and modifi ed variants with radial coolant fl ow, which are ideal for through holes.
