How we do it... The manufacturer will take a slightly larger, freshly made HSS Forstner bit and grind it to your requested diameter. At that point, all that remains is to replace the old engraving on the shaft with the new 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 'Stern' in Austria.
Please note - All custom Forstner bits are made to a tolerance of +/- 0.05mm (0.0019 inches)
