Drawing upon years of experience in making the best forstner bit and forstner bit set available, the Stern forstner drill bit has been redesigned to include a tooth-like pattern on the outside rim of the tool. These teeth assist in the cutting action, and yet still offer the same advantages of the traditional forstner bit. These bits are guided by their circular rim instead of their center, and consequently will bore any arc of a circle and can be guided in any direction regardless of grain or knots. Bores a flat bottom hole.
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)
