Made of carbide steel material and has high hardness characteristic
The shank that fits into the drill has three flattened surfaces, making them less likely to slip in the chuck. Much much easier to use than hand reamers!!! NOT AS DESCRIBED: The title says these are both carbon steel and carbide steel, but they are not the same. carbon steel and carbide are not the same; they are fundamentally different materials with distinct properties. Carbon steel is a metal alloy of iron and carbon, known for flexibility and toughness. Carbide (often Tungsten Carbide) is a ceramic-like, extremely hard, and brittle compound used for cutting, offering much higher wear resistance and heat tolerance. These have the look and feel of carbide, and not carbon. In my expert opinion. Most tires are "steel belted radial" and it is hard to ream through the steel belts by hand. I have spent HOURS trying to ream through difficult tire punctures by hand! These bits make quick work of the process. If needed, the sizes can be used gradually from smallest to largest. They leave a smooth sided hole which is less prone to leakage when the tire plug is inserted. Excellent value for the money! Highly recommended.

Makes plugging faster
It makes to process of plugging a tire a lot faster. I think you need to use a drill with these. Unless you had a hand drill with a chuck to tighten down on the bits, you probably wouldn't be able to use like a t-handle because you couldn't pull the reamer bits out. Just in case you were thinking of keeping this in a roadside emergency kit. It turns probably a 30 minute job into a 5 minute job with a drill though. I attached a picture of the hole after I was done reaming with all 3 sizes up to the largest.
