Fulton 25cm Long Forstner Bit Extension
Drilling with forstner bits to achieve a flat bottom hole or to start a deep hole turning project like on a larger vase or vessel is essentially impossible with a standard length forstner bit. To remedy this issue we have developed an extra long, heavy duty steel extension that allows you to secure a forstner bit into the end collet.
About this item
Drilling with forstner bits to achieve a flat bottom hole or to start a deep hole turning project like on a larger vase or vessel is essentially impossible with a standard length forstner bit. To remedy this issue we have developed an extra long, heavy duty steel extension that allows you to secure a 3/8 inch shank forstner bit into the end collet.
The forstner bit extension gives you an additional 8-1/2 inches of reach to bore deeper into your projects. This will help you create larger diameter starter holes or help when you need to drill in just a little further than the standard bit length will allow. The extension can be used with forstner bits on drill presses, lathes with a drill chuck installed (drill chuck not included) or with a power drill.
One of the most common uses for the forstner bit extension is for woodturners who need to bore out starter holes on larger vessels. However, the extension works exceptionally well for projects like salt shakers, pepper mills, or even wood turned beverage mugs. Contractors use the extension when they need to bore deep holes for running cables or wires and they also use it for joining larger timbers.
The forstner bit extender is made from solid, heavy-duty machined steel. It is designed to be used with forstner bits only. The collet inside diameter is 3/8 inch. This tolerance is very tight and designed to accept forstner bits with shank sizes of 3/8 inch or slightly smaller. Please note that some forstner bit manufacturers produce bits that say 3/8 inch shank size when in fact they are not. If you measure your bit shank and it is 3/8 inch, your bit should fit once the set screws are loosened.
- Collet inside diameter: 3/8 inch
- Collet outside diameter: 25/32 inch
- Minimum hole size: 13/16 inch
Please note that forstner bits and machinery shown in pictures are NOT included.
