The Challenge
A customer manufactures and maintains components for offshore oil rigs. They use a Johnsford VMC with 1000 PSI coolant through the tool. The part they are machining is a component for a locking collar for an offshore pipe wrench made out of alloy steel.

Tool used: Cobalt drill (27/64" diameter)
  • Hole diameter = 0.421″
  • Hole depth = 1.20″
  • Tap drill size for ½ -13 threaded hole
  • 110 SFM
  • 0.004 IPR
  • Cycle time = 23.53 seconds
  • Tool life = 468 inches
Seeking to improve their production process, the customer wanted to decrease machine cycle time.
The Solution
Allied recommended the ASC 320 solid carbide drill.

Tool used: ASC 320 drill (3.5xD) (item #335E04219A21M)
  • 300 SFM
  • 0.011 IPR
  • Cycle time = 9.4 seconds
  • Tool life = 2,016 inches
The Advantages
The ASC 320 not only reduced cycle time, but it also decreased the cost of production while increasing shop capacity.
  • Decreased cycle time by 60%
  • Increased tool life by 330%
  • Eliminated spot drill operation
  • Total cost savings = $564.45 or 63.76%
