Review on 🪵 TIDEWAY Shank Forstner Woodworking Cutter: Precision Cutting Tool for Woodworking Projects by Ryan Olsen

If you need a little wiggle room, this might not be what you're looking for. The block I have is just under 25mm which makes the fittings very tight. I have two other 25mm bits that don't have this problem (but they don't sink as low as their shanks are much shorter). It works well though and the fact that the end of the shank is triangular means your drill press will hold the drill bit much more securely than other cheaper round bits.
