Very sturdy bit extension. I ordered it to cut down and use as an extension for my fly tying vise with a 3/8" shaft, but may just keep it for use with 3/8" shaft drill bits.High quality steel construction.

This is a solid piece if steel that will extend the reach of your Forstner bit in your lathe chuck. The extension includes Allen fittings so you can lock your connection together.
