The competitor’s end mill showed an obvious decrease in surface finish quality as it reached the end of its tool life.
The S-Mill maintained a quality finish throughout the extent of its long tool life.

The S-Mill’s sharpness reduced the occurrence of burrs and increased tool life compared to competitor’s tool.
The sharp cutting edge also produced noticeably less sound than the current tool.
