Due to the different shape of the inserts, the tip angle changes from the minimum 35° to the round blade, and the corresponding tip angle is selected according to different workpieces.
Each shape has its own unique characteristics:
- Some provide the high strength required for roughing
- Some have good accessibility during profiling cutting
Each shape also has its own limitations. For example: high accessibility during machining means that the cutting edge strength is worse.
What’s the difference between a big tip angle and a small tip angle?
|Big tip angle||Small tip angle|
|Stronger cutting edge|
Higher feed rate
Increase cutting force
|Weaker cutting edge|
Reduce cutting force
What’s the difference between a big corner radius and a small corner radius?
|Big corner radius||Small corner radius|
|Very high feed rate|
Large depth of cut
High cutting edge safety
Increase radial pressure
|Best for small depth of cut|
Low cutting edge strength
