Premium Cobalt Jobber Drill Bits Set (6-Pack) - High-Speed Steel USA Made - Ideal for Metal, Wood, and Plastic Drilling - Champion Cutting Tool 705C Series

I’ve used A LOT of drill bits over the years and these are by far the best so far. I used these mainly to drill through some trailers when I was replacing the floor. It took about 1.5 bits to do a 20 ft gooseneck which is about 70 holes through 1/8-3/16” steel. The only reason it didn’t last longer is some of my holes lined up with the old screws that I couldn’t get out.These arrived just as advertised. A pack of 6 jobber length, cobalt steel, letter size O drill bits that are made in U.S.A. They're sharp, precise, and all around a great purchase. I won't hesitate to buy again. 5 stars.very goodEverything about this purchase was 5-stars. They arrived as a 12-pack of cobalt drill bits as expected. They are letter size H and made in USA. Sharp, precise...everything I was expecting from this brand. I will not hesitate to buy these again.
