Drills are often needed to create holes for numerous reasons. And one of the best tools for this job are the 3pcs HSS Titanium Coated Step Drill Bit. These drill bits work at a faster speed, saving you a lot of time while working. Perfect for any DIY projects, constructions, and home improvements.
Works on different materials
You can use these to drill holes to any materials. Work on plastic, woods, and most metals, including steel, brass, aluminum, and copper.
Perfect Fit Shanks
The shanks are small enough that they should fit any standard size chuck such as that on a small drill press or hand-held drill.
Made of high-grade material
The drill bits are made of drop forged, heat treated and fully polish classic high-speed steel with Titanium coating for proven capability and durability.
Comes in different sizes
Comes in three sizes: 4-12mm with 5 steps, 4-20mm with 9 steps and 3-12mm with 10 steps. This takes the guessing out of drilling by supplying the proper depth for you.

Needed only one of these but thought why not get more since it wasn't that much more expensive than buying a single drill bit from a big name brand. Does exactly what it needs to and works very well! Tried it on both wood and plastic and these bits are superb. Also comes in a little carrying pouch which is nice!
The drill bits are impressive! I drilled through 1/4" steel no problem. The material appears to be very strong titanium. After a few sheets of steel, the edge appears to be in good shape and still sharp!
For the money these can't be beat. Sure, are there better carbide step bits out there? Yes. Do they cost five times more than these for one bit? Absolutely.
I have used each bit a number of times. They have gone through soft steel, stainless steel, plastic, clutch plates, and aluminum with no issues.
If you are a professional fabricator that uses these multiple times a day then you probably need something better. For the rest of us that are weekend mechanics and tinkerers these work great.
These really surprised me. I thought I would be lucky to get 1 cut into a 3/8" plate. I considered this option for the drill press as I had a 1 3/8" hole to drill on the 3/8" plate. It did not get hot and cut through nicely. It saved me tooling costs as I was almost ready to purchase an annular cutter for the application. The amount of time it took I will use this method. The cost to production ratio was better than expected. Note I did use this with a drill press.
I purchased this set so I would be able to drill some holes in aluminum I was using for backing brackets for a project I'm working on. I've never used something to drill holes besides a drill press. These bits came very well packaged and in great condition. I like this set because it has multiple sizes and depths it can do. I tested it out on some scrap aluminum I had in the garage and it was a champ. These bits are well made and very durable. I'm glad I was able to add these to my tool collection. I highly suggest this set to anyone looking at buying one.
