Our team was presented with two challenging projects.. here is an overview of the challenge and outcome.

Project: Our Client required material drilled on 316 Stainless with drills run on a 40 taper VMC.

Challenge: The First drill was 1.125" diameter, running at 933 RPM the holes were drilled 1.365" deep in one pass at 3.75 IPM.

Outcome: The drill produced better than a 40 micro finish and after a run of 35 parts the inserts minimum to no signs of wear.

Challenge: The second drill was .750" run in the same machine and material.

Outcome: This drill was run at 1375 RPM .800" deep at a feed rate of 4 IPM with the same performance after 35 parts.
