In case it matters, two days ago I drilled four 1-3/8 inch holes, 1/2 inch deep into the end grain of a mahogany turning blank. 1-3/8 inches is slightly larger than the 32 mm that @Shay
wants. It isn't that large.
(After that, I drilled four 7/8 inch holes, 1/4 inch deep in the center of the previous holes.)
I tried my old Forstner bit on my underpowered drill press, but got nowhere. The bit burned and burnished the wood, but it would not drill, even when I applied enough pressure to almost stall the drill press. I looked at the Forstner bit and it is shot, probably past the point of salvaging with diamond files.
I bought a new Forstner bit it made all the difference. The new bit drilled correctly, but the drilling was still slow. I am methodical, but it took me a couple hours to measure and make the holes. Some of the time was spent checking the depth, and some of the time was spent clearing the hole along with resting/cooling the bit.
My point is that drilling a large hole in end grain hardwood can be slow. It takes a sharp bit, plus time and patience. Take small bites and allow time for your drill bit to cool between bites. Keep the hole clear as you drill.
