The Challenge
A customer manufactures ball screws, aerospace actuators, and landing gear actuators for the aerospace industry. In this application, they are using an Okuma VMC with 750 PSI through-tool coolant to machine a gear actuator housing made from cast stainless steel.

Tool used:  Guhring RT800 drill
  • Hole depth = 0.25″
  • Hole diameter = 0.7030″
  • 733 RPM
  • 0.007 IPR
  • 5.13 IPM
  • Cycle time = 15 seconds
  • Tool life = 10 holes
Unsatisfied with their current process, the customer needed to increase tool life and reduce the cost of production.
The Solution
Allied recommended the Original T-A drill.

Tool used:  Original T-A drill insert (item 1C51A-.703) with holder (23010S-100L)
  • 760 RPM
  • 140 SFM
  • 0.008 IPR
  • 6.08 IPM
  • Cycle time = 14.5 seconds
  • Tool life = 40 holes
The Advantages
The Original T-A drill achieved the customer’s goals by increasing tool life while lowering the overall cost of production.
  • Increased tool life by 30%
  • Total cost savings = $361.65 or 85.2%
