3. Fulton


Fulton 6 inch Long Forstner Bit Extension for Adding Over 5-5/8 inches of Drilling Depth to Your Forstner Bit. for Wood Turners, Furniture, Carpentry and Construction

Fulton #ad - 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. 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.

Please note that some forstner bit manufacturers produce bits that say 3/8 inch shank size when in fact they are not. To remedy this issue we have developed a heavy duty steel extension that allows you to secure a 3/8 inch shank forstner bit into the end collet. Forstner bits and Machinery shown in pictures are NOT included. The forstner bit extender is made from solid, heavy duty machined steel. The minimum size hole this extension will allow you to drill is 13/16 inch. The collet inside diameter is 3/8 inch.

This means the set screws may protrude outwardly from the collet. The reason this is important is that as we mentioned earlier, some bits may have slightly different shank sizes. The collet outside diameter is 25/32 inch without the set screws protruding outward. This tolerance is very tight and designed to accept forstner bits with shank sizes of 3/8 inch or slightly smaller. However, the extension works exceptionally well for projects like salt shakers, pepper mills or even wood turned beverage mugs.
