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 1/2 inch shank forstner bit into the end collet.
  • The forstner bit extension gives you 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 1/2 inch. This tolerance is very tight and designed to accept forstner bits with shank sizes of 1/2 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 1/2 inch, your bit should fit once the set screws are loosened
  • The collet outside diameter is 29/32 inch without the set screws protruding outward. The reason this is important is that as we mentioned earlier, some bits may have slightly different shank sizes. This means the set screws may protrude outwardly from the collet. The minimum size hole this extension will allow you to drill is 15/16 inch. Forstner bits and Machinery shown are NOT included. PLEASE NOTE: Your drill must have a 1/2” chuck in order to accommodate this 1/2” diameter shank.

The collet is 1/2” but it turns out my porter cable set of Forster bits are 3/8” shank. I saw forstner and got all excited and ordered this thing. My bad.The other problem is the outer diameter of the collet is just over 7/8” wide. Since I am drilling a 7/8” hole, it wasn’t able to extend my drilling at all.

This thing is really awesome and exactly what I needed except for one caveat. It's really long. I know, I know, the point of getting one is that it's long , but I didn't realize exactly how much it would extend so that putting a hole into a foot long piece of wood means when I am using a forstner bit on my drill press I have to start the hole without the extender and then drop the bit into the hole with the extender attached and reconnect it to my drill press. I also had trouble getting my 1/2 shank bit out of the extender and the set screws cut some marks into the shaft. I had to use some WD-40 to get it out. It is making the holes straight through like I wanted though so A+ with that.

Fulton makes great bit extensions. I own several and can not make up anything negative. My 4 5/8 inch forstner bit with this extension on my lathe works perfect. The grub screws and allen wrench have never failed me in any Fulton extensions I own.

La pieza es de buena calidad y bajo precio.Lo malo es que no tengo y además no encuentro (para mis necesidades) brocas con el diámetro adecuado para la extensión.Casi todas son de 3/8" o menos (aptas para broquero) y la entrada de la extensión es de 1/2".

The first thing I noticed is how nice the finish and machining is on this extension. So far it's perfectly balanced and shows no sign of deviation. I took off 1 star due to the depth of the set-screw threads as they are very shallow. You're obviously not going to crank on the screws but when loosened, they are VERY close to falling out.

This is a really good product. Used with Forster bit to bore holes for coring out lathe turnings. For 1/2 inch shanks only. Won’t work with 3/8 inch shanks
