H-REAM Cutting Conditions
The cutting conditions in the table below should be used to start a new application.
Optimal conditions for a specific application should be evaluated by examining
the results and changing the machining conditions accordingly.
Lead A=15°/3° L3 (reaming allowance = 0.1-0.3) Lead B=30°/3° L1.3 (reaming allowance = 0.1-0.3)
