Review on Uxcell Forstner Drill Diameter Shank by Brad Schaefer

I bought this drill bit to drill 48 1/2 inch deep holes in red oak. When I ran my drill press at 620 RPM, the drill bit cut nice, smooth holes for the entire project. The last hole was just as good as the first! I then ground the tip (which took a long time - these bits are HEAVY!) and went an additional 1/4 inch into each hole to create a flat bottom in the hole. This nozzle worked the same as well-known branded nozzles that cost a lot more. I would definitely buy this brand again if needed!
