T-A® Drill Inserts Alloy Steel
 
A contract machine shop that repairs and maintains equipment for the oilfield industry is machining a down hole mud injection tube used in offshore drilling made out of heat treated alloy steel. They are using a Manual Lathe running with water soluble oil coolant through the tool with RCA.
Previously, the customer was using a Nachi Cobalt Twist drill running at a speed of 475 RPM and 0.005 IPR with a cycle time of 4.7 minutes. The tool created a 10.0″ deep hole with a 0.750″ diameter and had a life of 8 holes. Seeking to improve their production process, the customer wanted to reduce the tool’s cycle time and decrease the cost of production.
 
AMEC's Solution
AMEC’s Application Engineers recommended a T-A® drill insert, item #151A-0024, with holder #27010S-100L. It was advised that the tool be run at a speed of 750 RPM and 0.0065 IPR. The results were excellent. Using the T-A® tool, the customer lowered cycle time to only 2.55 minutes and increased tool life to 11 holes. Also, the customer received a substantial cost savings. With the AMEC cost per hole being only $5.78 compared to the competitor’s cost per hole of $14.14, the customer saved a total of $836.58 or 59.15%.
 
Benefit
Due to the successful performance of the AMEC tooling, the customer lowered cycle time and increased tool life. They also lowered their cost of production by 59.15%.
