I decided to run some parts in brass so I could shoot good video without all the coolant running! The grip is a tricky little part. The largest drill is 1/4″ and the smallest is 2.8mm. That is the smallest size drill OSG makes with coolant through. I wasn’t sure it would be possible to do the whole thing without flipping the part to machine the other end, but I managed to get a way with cutting the final contour on the tip and parting off with the same tool. Not really how it’s supposed to be used, but it works! There is still a manual debur operation of the opening at the tip, but I set that up on the Bridgeport and it goes pretty fast.
