Champion Cutting Tool 705C-5/16 Cobalt 5/16-Inch 135 Degree Split Point HSS HD Jobber Twist Drill Bits, 6-Pack

I'm getting better, but I'm pretty hard on drill bits, so getting the cheap ones end up costing me more money. I came across the Champion Cutting Tools & I am very impressed with the quality of these bits. I've been drilling holes in 2 1/4 oil field pipe and I'm still on the first drill bit after 68 holes. It's showing some wear, but still cutting through it like it was wood. A couple of times the bit got in a bind and twisted the drill out of my hands. Any other drill bit would of snapped off. I own several sizes of this brand & they are all like this review. Save your money and try these & you'll wish you did years ago.

thanks
