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. ## Features - Superior M35 Cobalt Construction- This 4-Spiral Flute step drill is crafted from M35 cobalt high-speed steel (HSS), ensuring exceptional sharpness and durability.
