Product description Worture Step Drill Bit Wide Application- For Metal Wide Application- For Wood Suitable for Various Materials Review: Step drill bit - I recently purchased the WORTURE M35 Step Drill Bit (3/16” to 7/8”, TiAlN Coated), and it has exceeded my expectations. The build quality is impressive — the M35 high-speed steel combined with the TiAlN coating makes it extremely durable and resistant to heat, which is perfect for working with both soft and harder metals. The bit cuts smoothly and accurately. Each step transitions cleanly, and I noticed minimal burrs on the edges after drilling. It handled stainless steel, aluminum, and even some thicker steel sheets without any issues. The precision and sharpness mean fewer passes and less wear on your drill, which is a big plus. I also love the convenience of the stepped design. It’s perfect for enlarging holes without changing bits constantly, and the size markings are clear, making it easy to pick the exact hole I need. If you’re looking for a reliable, heavy-duty step drill bit that stays sharp, reduces heat buildup, and delivers professional results, this WORTURE M35 is worth every penny. Highly recommended! Review: Strong - Strong. Worked through bike rack hitch insert. Can go “sideways” well if hole is not exactly right the first time. Also used recently on hitch strut supports to extend one bolt installation hole. Worked well. No visible wear.

Decent step drills
I bought these for my son to use. Everyone should have a decent set of step drills in their toolbox, they're very useful . So far their performance has been very good.

Step bit works
Why did you pick this product vs others?: I needed a tool that could increase the size of an existing hole. This one was priced right and offered the capability to do it.

These work great.
I have a love and hate relationship with step bets. These work great as so many others, but as soon as that tip wears out. But I love theses things. It's a whole drill index on one bit, and the price is good too.

Huge bang for the buck
I used this to widen a hole in 1/4" steel plate and it not only worked, but drilled a very nice circular hole. This is the best value for a stepper bit that I've seen
