Each bit is forged from premium high‑speed steel and finished with a striking gold coating that not only adds visual appeal but also provides an extra layer of corrosion resistance. The set includes a range of fractional sizes from 1/16″ up to 1/2″, incremented in 64ths, ensuring you have the right diameter for any fastening or drilling task.

The bits are rated for a cutting diameter of 0.5 inches, making them suitable for a wide range of applications, from automotive engine work to general construction tasks. The set’s weight of just 2.4 ounces per bit ensures that the overall mug remains lightweight, reducing fatigue during extended use.
