Best Hole Enlarging Drill Bits

Fulton 10 inch Long Forstner Bit Extension for Adding Over 8\ of Drilling Depth to Your Forstner Bit Ideal for Wood Turners Furniture Carpentry and Construction (3/8 inch Collet)

  • 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 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 forstne....
