The Challenge
The customer is machining a steel component made from H13 using a horizontal Okuma L106 lathe with 200 PSI internal coolant.

Tool used: Sandvik indexable drill with two inserts
  • Hole diameter = 1.96" (50mm)
  • Hole depth = 5.9" (150mm)
  • 900 RPM
  • 0.002 IPR (0.05 mm/rev)
  • 1.8 IPM (45.72 mm/min)
  • Cycle time = 3 minutes 17 seconds
  • Tool life = 6 holes
  • Process required pecking
The customer was unhappy with the long cycle times and short tool life. They needed a better solution to solve these issues.
The Solution
Allied recommended the Revolution Drill.
