Inset screws too long
WoodRiver 3/8" x 4" Forstner Bit Extension
I got this extender to make longer holes with a 3/4" Forstner bit - I figured since it was 3/4" diameter, it would work with my 3/4" Forstner bit. I figured wrong. The set screws protrude about a 16th" making it useless for 3/4" holes. Should work well with 7/8" or 1" bits. Sturdy construction and good precision. My only regret is that they don't spell out what size bits it will work with.
No, I would not recommend this to a friend
Good solid extender when needed.

Critical When You Need IT
As a turner, one needs to drill holes deep in a spindle project, like a pepper mill. On a Midi Lathe, there isn't the space to just use a long bit extender.
I bought 2 of these extensions. Drill in to the depth of the extension. Add a second 4" extension and drill to that depth. Go to the 10" extension and your done.
Ft Myers, Fla
Attachment end a little large if drilling smaller size holes.
