About this item












3/16 to 1-3/8 Inch Cobalt Step Drill Bit for Multi-Size Versatility
This cobalt step drill bit has nineteen exact hole sizes, from 3/16 inch to 1-3/8 inch, so you don't have to stop what you're doing to switch tools. It's easy to drill clean holes in a wide range of sizes, from small test holes to larger ones for pipes or fittings.
You can also adjust the hole size by applying pressure as you drill deeper. This makes the work more accurate and clean. This helps you work more easily, especially when you need to slowly change the size of something without damaging it. With confidence, you can fix things around the house, do electrical work, or work on projects in the workshop.
Cobalt Step Drill Bit: 3/8 Inch Triangular Shank for Quick and Secure Fit
Most standard cobalt step drill bits have a 3/8-inch triangular shank, which provides a safe, stable grip. You don't have to worry about this bit falling or being out of place when you put it in and take it out of your drill. This design makes it easy to use with a variety of tools and set up projects quickly.
You'll notice how stable it is when you drill into metal or wood. Because it is triangular, the bit doesn't spin in the chuck, so you always have control. You keep your hand straight and get clean results even when drilling through harder materials.
TiAlN Coating on Cobalt High-Speed Steel for Long-Lasting Sharpness
The cobalt high-speed steel with a TiAlN layer in this step drill bit makes it work well. This high-tech covering keeps the bit sharp for a long time and protects the cutting edges. It takes less work to drill into hard things like aluminum, stainless steel, and sheet metal.
Also, less heat builds up while you drill, which protects both the bit and the material. Less heat means cuts and holes are smoother, with no burning or rough edges. It takes less time to cool the bit or get new tools when the old ones wear out. This makes things last longer, which helps you get things done faster and better.
Four-Flute Design with 118° Tip for Optimized Cutting
The cobalt step drill bit has a 118-degree tip and four flutes, which help clear chips quickly and reduce friction. You can drill holes in metal, wood, plastic, and fiberglass that are clean, exact, and free of burrs. The best tip position also makes it easy to start drilling without having to move across the surface.
You'll see how easily the bit cuts through both thick and thin materials. The shape helps keep the bit from sticking and lowers the temperature. This bit makes the job easier and more professional, whether you are drilling new holes or enlarging existing ones. It's a useful way to drill quickly, accurately, and cleanly.
Works on Materials Up to 1/8" (3 mm) Thick
For materials up to 1/8 inch (3 mm) thick, this step drill bit works great. You can confidently drill through metal panels, wood planks, plastics, fiberglass, and stainless steel sheets. The thickness range is flexible enough to meet most home and business uses.
You don't need to keep different kinds of tools on hand. You can work quickly on various surfaces with this single step drill bit because you don't have to switch bits or tools. It makes home improvement, auto repair, and fabrication jobs easy, and even if you're a beginner, you can get professional results.

You can use this cobalt step drill bit on various types of materials, making it a useful tool. It works on almost all surfaces, like metal, stainless steel, wood, plastic, and fiberglass. For example, you can use it in your shed, workshop, or on the job site.

Because it's so flexible, you can use it for plumbing, electrical work, home improvements, or making things.
High-Speed Steel Construction for Maximum Durability
The cobalt high-speed steel used to make this step drill bit is strong and effective for tough applications. Cutting at high RPM is possible with this material without it warping or losing its edge. The bit will stay in shape even after drilling through metal sheets, stainless steel, and other tough materials.
Additionally, the long-lasting durability gives you value. The bit doesn't wear down quickly, so you won't have to change it very often. You don't have to switch tools to work with soft materials like plastic and harder metals. The strong steel ensures that the holes remain clean and the same size.
