The Challenge
A mold shop that specializes in small production parts for the tool and die industry is machining a stainless steel proprietary component that requires drilling 4 holes. They use a Mori Seiki VMC running with 250 PSI through-tool coolant.

The customer tested 2 tools to compare the results.
  • Hole depth = 0.630″
  • Hole diameter = 0.3543″
Tool 1:  Sumitomo solid carbide drill
  • 2480 RPM
  • 230 SFM
  • 0.004 IPR
  • 9.92 IPM
  • Cycle time = 4 seconds
  • Tool life = 150 holes
Tool 2: Guhring solid carbide drill
  • 2480 RPM
  • 230 SFM
  • 0.004 IPR
  • 9.92 IPM
  • Cycle time = 4 seconds
  • Tool life = 150 holes
Needing better results than these tests showed, the customer requested a solution to reduce cycle time and decrease the cost of production.
The Solution
Allied recommended the ASC 320 solid carbide drill.

Tool used: ASC 320 drill (item 335M09000A21M)
  • 2480 RPM
  • 230 SFM
  • 0.006 IPR
  • 14.88 IPM
  • Cycle time = 2.5 seconds
  • Tool life = 500 holes
The Advantages
The ASC 320 successfully reduced cycle time and increased tool life for the customer.
  • Reduced cycle time by 1.5 seconds
  • Increased tool life by 233%
  • Total cost savings = $408.94 or 67.0%
