Helix angle and rake angle

Helix and rake angles are particularly important characteristics of milling tools. Due to this fact, helix
l 45° angle l and rake angle g are specified for each tool. The exact values can vary with the tool diameter.
g 5°

Crash angle α
Tools with a smaller cutting diameter than the shank diameter need specific attention during machining.
A crash can surely be avoided when the limiting side surfaces are sloped with at least a minimum angle,
the crash angle α, against the vertical.
The angle of collision is stated for each diameter in the data table on the catalog page.
