Thread: Boring Head
24/09/2021 19:40:02

Minimum bore size is dependent upon the size of the tool, as many have already stated, and more importantly by the thickness and rake angle of the HSS or tungsten carbide tip. What will happen trying to bore too small a hole is the bottom of the TC bit will likely hit the workpiece first and scrape the bore and it will get very hot. I've just bored out a hole to 34mm diameter but it wasn't until I got out to near 24mm that it started to cut correctly.
