The Challenge
A customer manufactures large bearings for turrets on military humvees. The turrets are made from aluminum. They use a vertical Makino to manufacture their products

Tool used: Carbide twist drill
  • Hole diameter = 0.2656″
  • Hole depth = 2.00″
  • 417 SFM
  • 0.003 IPR
The customer also used a high speed steel reamer in the production process. Because it took one hour to ream the hole, the customer needed to update their tooling.
The Solution
Allied recommended the ASC 320 solid carbide drill.

Tool used: ASC 320 drill (item 390E02656A21M)
  • 417 SFM
  • 0.011 IPR
The Advantages
The ASC 320 successfully eliminated the reaming process in this application.
  • Eliminated the reaming process
  • Total cost savings = $460.62 or 67.37%
