## Description

Each step drill bit manufactured by NEIKO comes with precision manufacturing and is built with high-grade high-speed steel. Our step bits, or known as unibits, come with a titanium coating that promote the strength and cutting power of each of these drill bits. In this 3 piece set, you get a total of 31 step sizes to create clean holes in metals, plastic and wood. The spiral grooved design deburrs faster and gives you clean cuts every time. Each bit set is engineered for faster drilling and you can have confidence in knowing you will get the job done with accuracy and efficiency with bits that truly perform. Need a center punch to start your hole drilling? Be sure to check out the 02638A 5" Center Punch and the 02639A 6" Center Punch.

Review: worked well on thin sheet metal - We were working on a craft project that required holes through small sheet metal covers to mount solar lights. The holes were 11/16 inch diameter and these step bits cut a nice, clean round hole in the metal. The bits have angled shafts to prevent rotation in the drill chuck, and seem sturdy and sharp. For cutting something thicker, like wood, I think it would work easier to see clearly when the various step levels occur, because you have more resistance. But overall these worked great for our project, and a new addition to the variety of drill bits we need and use around our DIY projects.
Review: Excellent - I'd give it 6 stars if I could - I'm not a professional carpenter but I always seem to be building and fixing things just the same. I have owned various tools, drills and drill bits over the years yet somehow I had never heard of a "step" drill bit. Where have I been? A need came about where I had to widen the diameter of some pre-existing 1/2" holes I had drilled in 20/24 gauge steel. These holes were being placed in the back walls of a Tennesco metal office drawer ( B0057NFQWM ) - the back wall and the back of the drawer. So I attach this Neiko Titaniaum Step Drill bit to my Ryobi 9.6V cordless drill and to my amazement it quickly & effortlessly removes all the "slag" left over from the initial drilling attempt. It then widens the holes very quickly in progressively larger increments as I press the drill harder and just persist for a minute of drilling. I am impressed! This * EXACTLY * solved my installation problem. The fact that it does it's job so quickly and cleanly and I don't have to do any metal filing cleanup work made my day. It does not warp the metal either. Yes, it throws curlicue metal shavings around but that's a given. Easier to clean those up than the micro-fine metal filings from a conventional drill bit. TIP1: Since I started with a pre-existing pilot hole I cannot speak to whether this will work without a pilot hole. I suspect it would be * wise * to have * some * kind of basic pilot hole - even if it's 1/16 inch. TIP2: I did not use any lubricant's on the bit, but in retrospect, for the sake of bit longevity, it probably would have been a good idea. NOTE: My 9.6V cordless drill balked at doing the last two (widest opening) "steppings" but rather than getting out the electric powered drill, I said "good enough" at that point. The holes I had created were more than wide enough to feed Ethernet cables w/jacks through or 14/3 SJT cord - with a fair amount of remaining "slack" space. Highly recommended if you need to make clean holes in 20 to 24 gauge sheet metal.
