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. One of the most common uses for the forstner bit extension is for woodturners who need to bore out starter holes on larger vessels. Forstner bits and Machinery shown in pictures are NOT included. The reason this is important is that as we mentioned earlier, some bits may have slightly different shank sizes. This tolerance is very tight and designed to accept forstner bits with shank sizes of 3/8 inch or slightly smaller. 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 forstner bit extension gives you additional 5-5/8 inches of reach to bore deeper into your projects.

Furniture, Carpentry and Construction Use 10" x 1/2" Extension for 1/2" Forstner Bit, 10” Long Forstner Bit Extension For Adding Over 8" of Drilling Depth To Your Forstner Bit. For Wood Turners
#adPeachtree Woodworking Supply #ad - 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 extensions will work with hex shank or round shank forstner bits. Can be used with hand drill as well. 1/2" extension will only work with 1/2" drill chucks. The 10” forstner bit extensions are available in two different shank diameters: 3/8” and ½”.

To be certain, please make sure your bits fall into the correct socket size before purchasing. The bits are secured with two hex socket set screws using a hex key wrench which is included. 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. Unlike other brands of forstner bit extensions, this extension is non proprietary so they will work with most any brand of forstner bit. Worse yet, even with a standard length extension you’ll probably only add about 3” of depth to your bit. This means that the 3/8” extension will accept 3/8” shank forstner bits while the ½” extension will accept ½” shank forstner bits. 10” long by ½” extension has an inner diameter of ½” and an outer diameter 57/64” and works with bits 15/16” in diameter or larger.
