Featuring a 135-degree split-point tip and a 2-flute design, this metal hole cutter will bore through almost any surface, including steel, wood, and other materials. It’s designed in a cone shape to automatically tap, drill, and deburr holes in one simple step.Our step bit is constructed with high-speed alloy steel and features a titanium nitride coating for added durability, longer life, and cooler, faster, and cleaner drilling. To use, place the tip of the bit against the sheet of metal or slab of wood you’re working on and drill to the precise measurement you need. There’s no need to purchase multiple bits when you can get the job done with one easy drill bit.This step drill bit for metal can drill holes in the following sizes: 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", and 3/4". You can use our high-speed drill bit for steel jobs at home or work, and its small size allows you to pack it in your toolbox and take it wherever you go. Whether you need a multifunctional drill bit to cut through stainless steel or a new step bit to add to your equipment, NEIKO has your back with our durable, dependable, and strong tools.

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: Great price and product! - Quality step bit! Does what it should and seems to be a long lasting product!

### ⭐⭐⭐⭐ Worked great
*by S***. on July 12, 2016*

Drilled a hole in my stainless steel sink for an air gap for the dishwasher in about 10 (fairly exciting) minutes of drilling. I needed a hole the entire size of the bit so this put it through a pretty good test. For a small hole this could've done the job in seconds. I'm fairly handy but this was my first attempt at cutting stainless steel or with a step drill bit. I tried to start a pilot hole with a 1/16 titanium drill bit but was only successful at creating a little dent before it got obvious it was starting to get hot. I read reviews saying be careful about denting or heating SS so it doesn't work harden so I stopped. The little dent the 1/16 bit made was plenty to get started and keep the step drill bit on target. Used Tap Magic cutting fluid and followed advice to press hard and start slow. The bit dug right in and I had a small hole in just a few seconds. Every 30 seconds or so I stopped, checked my progress, wiped excess oil and metal and added fresh oil. As the hole got bigger the bit got stuck a few times. I had to go in with a little bit of speed to get the bit to spin without getting stuck once the hole got big enough. Had some smoke and hot pieces of smoking metal coming off the bit when I increased the speed . . . glad I did this when the wife wasn't home or I'm sure she would've stopped me and we'd be waiting for a plumber to finish the last 2 minutes of this job. The hole's not 100% perfect but it's decent and since it's covered by a gasket it works just fine for my needs. The bit shows a fair amount of wear, probably from going a little too fast, but at $10 I can buy a new one for every hole I make and still save a fortune even as a one-time-use tool.
