100R Series

Tool 100Ri625A

Roughing steel and titanium puts serious thermal stress on cutting edges. The 100Ri625A handles this with TiAlSiN coating over solid carbide. The aluminum content in the coating creates a thermal barrier that keeps cutting temperatures manageable when you're pulling heavy chips at aggressive feeds.

The 4-flute design balances chip evacuation with tool rigidity.
Chipbreaker geometry along each flute fractures chips before they can work-harden or pack the gullets.
The 0.008" chamfer strengthens the cutting edge against the impact loads you get when roughing interrupted cuts or scale.
This isn't a finishing tool.
Surface finish will reflect the aggressive parameters.
The 5/8" diameter gives you the mass to run the feeds these materials require without deflection.
Follow with a finisher for final dimensions and surface quality.
