9pc Step drill bits are constructed from traditional HSS combined with a titanium coating to make them even more durable. This also proves the capability and durability of the drill to last through multiple drilling on surfaces such as: plastic, aluminum, copper, stainless steel, and so much more.
- It’s great for sheet metal, aluminum sheets, wood chips, plastic and wood board. It’s a perfect choice for DIY and engineering use.
- Engraved Sizes Easily identify which size you need with the contrasted, laser engraved sizes inside the step drill bit flute.
- High speed steel along with titanium coating ensures outstanding durability and sharpness, can reduces the friction, runs cooler.
- Split point tip is at 118 degrees to increase the wear resistance. The two flute design provides a smoother cutting, allows the material particles escape easily for a much more clean drilling operation.
- Tri-flatted shank is a great universal fit that will give you confidence while you work knowing that your drill bit is securely in place.

My husband loved this! Perfect for making the required hole for our sink.
I purchased this to aide in adding a spoiler to my CTS coupe but got the job done before they arrived. They looks like a very complete set with any size you might need and comes with a very nice case. I haven't put them to the test yet. If they hold up then they deserve the four stars I've given them.
