INSERT BLANK PRE-DRILLED - This is a super nice wood insert blank that we cut on our CNC so they're precision drilled and sized. There's a 5/8" diameter shaft with an O-ring, and it's been pre-drilled with a tapered exhaust. You simply cut the toneboard and shape the bell end. We let the CNC do the precision work that is hard to accurately do by hand. So with a good portion of the hard work done you'll be able to complete the insert much quicker.
