Each WeldTec auger bit features a hard cutting edge welded to the base material. Auger drill bit features a long-lasting nail-cutting life. Wide flutes and a 3/8-inch quick-change impact shank make this a versatile auger drill bit. 1/2" diameter. 17" overall length.
According to my experience, this industrial drill bit is phenomenal. It cuts through tough surfaces with ease and has an extended lifespan. The quality is undeniable and the silver coating is a bonus.
Pros
Exceptional quality, cuts through tough surfaces with ease, extended lifespan, silver coating.
Sufficient for approximately 60 holes through pressure machined 4x4 with 2x8 on each side, ie approximately 6 1/2 inches per hole. I also tightened a few screws, which also reduced its lifespan. Generally worth the money.
