Universal forstner bits
MACHINE SHARPENABLE - These forstner bits will make a smooth, flat bottomed hole like any forstner drill bit, but with a really important difference. They are machine sharpenable! No more hand sharpening. These bits are top quality, high carbon steel.
Custom sizes are available upon request
Custom sizes are a special order items and may take up to 8 weeks to deliver. (Contact for details).
How we do it... The manufacturer will take a slightly larger, freshly made HSS Forstner bit and grind it down 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)
