Still Struggling With Dull Bits, Heat, and Messy Holes?
Ordinary drill bits can heat up quickly, lose sharpness, and slow down when working on harder materials.
Our Solution:
Made with industry-grade 6542 high-speed steel and 5% cobalt to improve wear resistance, hardness, and long-lasting drilling performance.
Basic drill bits often slip or “walk” before the hole starts, leaving scratches and inaccurate marks.
Our Solution:
Features a 135-degree split point with a straight shank to help prevent walking and make drilling more precise without needing a center punch.
Poor groove design can create extra friction, more heat, and slower drilling progress.
Our Solution:
Uses a fully ground spiral groove design that helps reduce friction and heat for faster, cooler, and cleaner drilling.
Many bit sets are hard to organize and do not cover the sizes people use most often.
Our Solution:
Includes 6 commonly used drill bit sizes with a portable plastic storage bag for easy carrying, storage, and organization.

Here’s Why People Trust the Cobalt Drill Bit Set
It’s become an essential for DIYers, repair workers, and hands-on makers who want cleaner holes and smoother drilling.
The biggest difference for me is how quickly the bit starts. It doesn’t skate around like my old ones, and the holes look much cleaner.

Great little set to keep in the toolbox. The sizes are practical, the storage bag is useful, and the bits feel sharp right out of the package.

I used water when drilling harder tile material, and the result was much better than expected. Smooth, steady, and easy to control.
