Drilling with forstner bits to achieve a flat bottom hole or to start a deep hole turning project like a large vase or vessel can be very challenging with a standard length forstner bit. Worse yet, even with a standard length extension you’ll probably only add about 3” of depth to your bit. This is often not enough of a depth for many of your projects and it can get quite frustrating without the proper tools.

With the 10” long forstner bit extension you can now add over 8” of extra drilling depth to your current forstner bits! That alone makes this extension especially ideal for woodturners when having to hollow out large vessels or objects like salt and pepper shakers. The extension also works great for rustic furniture, joining wide timbers, wooden beverage mugs and even works great on things like turned kaleidoscopes.

Can be used with hand drill as well. The 10” Forstner Bit Extensions are made from heavy duty solid machined steel and feature a 3/16” thick socket wall to firmly hold the bits in place. The bits are secured with two hex socket set screws using a hex key wrench which is included. The extensions will work with hex shank or round shank forstner bits.
