1/2" x 8" Auger Drill Bit with a 3/8" Shank. Solid center design for rigidity when boring. Coarse screw point provides fast boring in hard and soft woods. Quality Guaranteed.
So far this has worked well. It went through 3 inches of pine easily and would have gotten 5 stars, but I only got it two days ago and haven't used it on hardwood.
Definitely did the job. Used this to drill holes in giant beams that I used to build my kids swings. Use a good big drill and this drill will fly right through. A good thing.
