How we do it... The manufacturer will take an existing freshly made HSS Forstner bit. The chosen bit must be microscopically larger than your requested size. Next, that bit will be further ground down to your requested diameter. At that point, all that remains is to overwrite (replace) the old engraving on the shaft with the new (updated) size.
Unfortunately, the manufacturer won't have any economies of scale when producing a unique item so pricing reflects a more individualized cost to produce and ship.
Your custom made forstner bit will be hand made by the manufacturer in Austria.
If you have a preference between a Saw Toothed rim, Continuous (AKA Knife edge) rim or a wavy rim, please let us know before or during your order process.
