The size marks are stamped next to each step to ease the use.
  • Double spiral flutes for more efficient swarf clearance; 1/4 Inch hex Shank with quick release slot to eliminate slipping; Self-starting for clean holes in thin materials; M35 cobalt HSS to cut stainless steel. The step drill bit is made with M35 cobalt. It is ideal for variety of materials from stainless steel, metal, plastic, fiberglass to wood. They also help to enlarge existing holes. M35 HSSCo is a high speed steel alloy made up of 5% cobalt. M35 is similar to M2, but with 5% cobalt added.
  • The addition of cobalt increases heat resistance. It is widely used in metal manufacturing because of its ability to resist wear over conventional high speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes. M35 is also less prone to chipping when used for interrupted cuts.

A youtube video did a comparison of a bunch of different brands of step drills, this one was rated the best. I ordered it and it is really better than the other four brands that I have in my drill index.I have bought an assortment of three sizes of this same manufacturer, very happy with the product.

Drilled really well for a very short time. Kept it lubricated, speed down, and pressure up; but it blunted extremely quickly and just plain stopped drilling.

Works great. The spiral shape of cut reduces tear out. Highly recommend this tool.

Used this to drill 6 holes in a pickup truck frame to mount a towing receiver mount. It did the job fine, and I believe will still drill more holes. No complaints.

I’ve never used a step bit before and I have been missing out. This thing is amazing, it drills through metal with ease and it seems to continue to stay sharp. I have used drill bits in the past that were made for metal and they got dull so quick but this step bit keeps on going. I also use oil lubricant to help keep the bit cooler which I think helps a lot. I am very happy with this product and it was well worth the money.

Best Step Bit I've ever owned! Cuts so fast I have to slow the speed down to not go past the size I want. Price is almost as low as the cheapest ones.

There's nothing I dislike about this. Used it to ream the door hinges on my Suzuki Swift to accept stouter hinge pins and bushings. Very sharp, very effective. I'd recommend this tool
