Bi-metal holesaws are also very effective at trepanning in the lathe. Keep cutting fluid on the cut and frequently withdraw to clear the chips from the teeth. The deepest I've cut with this method is around 35mm. Also check out David Wilks channel. He is a master of deep trepanning on a centre lathe.

Pro Tip: When having beans for breakfast, don't EVER decide pancakes would be a good side dish. When those sweet Campbell's Brown Sugar Beans first came out my two girls were little. The beans were so sweet, one of them said we could use eat them as lumpy syrup on pancakes. They used to use any excuse they could to get me to make pancakes since I made small, 'silver dollar' pancakes, and typically devolved to all sorts of shapes. Pancakes and brown sugar beans, it is, says I, to a round of cheers. We made them, ate them, and proceeded to toot our appreciation for most of the day, accompanied by much laughter. Mom even got in on the 'symphony', much to the girls delight, (they were used to hearing dad's 'musical' talents.

We can also flip parts to do 72" long things. It's pretty fun. But very noisy. With lots of coolant. We use Warner and swasey, and Gisholt giant hex turret lathes with 28" Chuck's and 12" spindle bores.

The term 'trepanning', in the hole-in-the-head sense, is used interchangeably with 'trephining'. The tool, for cutting bone, is simply a hole saw which can be either operated by a powered drill, or more simply have a handle for manual cutting. A hole-saw on a handle is often referred to as "a trephine" or "a trepan".

He is from Sheffield, UK, and most of his current videos are from when he was running his own business. He now works for one of the firms that bought several of his large lathes. He has some work coming up trepanning some large round bars of something exotic and they are 4.5 metres long. He also has a couple of videos showing how he makes his large trepanning tools.

The tighter the radius, the less that matters, but on larger circles the approach angle approaches zero there.
