Stainless Steel
Imagine setting up a job. The last operation is to thread an internal hole with a 3/4-32 thread on a very expensive job, 15-5PH that is about 32 HRc. We had been running an indexable single point thread mill. Setup time was horrible, averaging 2.5 hours. Production time was just as bad: we only threaded 4 holes per hour. Tool life was only 40 holes per insert.

Our OSG rep suggested solid carbide thread mills with TiAlN coating that he said would reduce my setup time as well as increase tool life and productivity. I had to see it to believe it! When all was said and done, this amazing thread mill ran for 153 holes, an increase of 194%. Setup time was reduced to less than one hour. My productivity increased by about 450%! Calculated over the entire year, I saved over $16,000 in costs by using OSG EXOCARB® Thread Mills. Thank you OSG!

Inconel
I was using a European EXPENSIVE solid carbide thread mill in Inconel 718 that ranged from 42-44 HRc. Tool life with this thread mill was the best for any thread mill I had found in the market; that is until OSG provided 10-24 thread mill samples to test. I ran these and found the tool life to be over 30% better than what I was currently using! Not only that, the price on the OSG was considerably more affordable than the EXPENSIVE brand! I am in the process of switching all of my thread mills to OSG. What a great product from OSG!
