7/16" x 12" 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.
I purchased this auger to use on a construction site for digging holes for fence posts. It is extremely durable and makes quick work of any surface it encounters. The cutting edge is sharp and stays that way through multiple uses. The auger is industrial and scientific grade, so it can handle any tough job. The only downside is its weight, which can be a challenge to maneuver at times.
Pros
Durable, sharp cutting edge, industrial and scientific grade
Cons
Heavy weight can be cumbersome to maneuver at times.
Arrived next day and came in handy straight away to install the patio railing in my apartment building so required a lot of drilling. It continues to just chew wood and works great. I looked for 7/16" at all local hardware stores and crossed it out.
