Wobble Broach Tool Test in BioDur 108C (50 Hrc)

Wanted to share this wobble broach tool test received from a major orthopedic manufacturer. This is cutting in BioDur 108C which has an HRC of ~50. It is a very difficult and tough material to cut. Their application is making 2.7mm/3.5mm diameter screws with a range of 12-90mm in length. This test was done vs their previous broach supplier, with both broaches being used in a PCM holder. They were using 6000 broaches annually, at a cost of $137,000. They will save over $85,000 per year using our Rayco #7 material broaches, and have over 5000 less tool changes!

*One thing to note here is the customer mentioned that hardness varies bar to bar within the same heat on this material quite a bit, which is one a factor that creates a larger standard deviation. *
