Comment

Comparison of cutting surface

After 10 hours machining, DHR237 still can achieve high quality cutting surface.
In the rival products, the processing surface roughness could not be kept constant.

Comparison of tool wear

Because of the 37.5°helix angle, burrs, wave and cutting resistance have been effectively decreased!
DHR237 has 2 times tool life comparing to the rival products.

Upper burr amount

DHR237 suppressed the occurrence of burrs and achieved the sharp edges.
