I was pleasantly surprised with these drill bits as I just completed a task with the first bit of a series of pop rivet holes in 2.5mm steel as RHS posts (around 50 holes) and the one bit (one end) did the lot with a decent speed and no undue pressure without a breakage..... This is unusual in the construction industry.... It was better than I had expected for sure. My hope is that all the bits perform as well as the first. I recommend these bits based on this performance alone. Jim (Builder for over 50 years) retired.

These are the best pilot drills. Always use them if drilling a bigger hole. Great for rivets as well.
