Review: good quality - good for steel but not for stainless
Review: Drill America #54 cobalt drill bits (12 pack), Great value and they work well on steel - These drill bits are a good value, and they can actually drill a hole through 3/16" steel. I had purchased Max Tool No. 54 drill bits, and they would not penetrate the steel plate and were useless for my project, so I bought the Drill America no. 54 drill bits and they work great. I would buy these drill bits again.

## Features

- Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys
- Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools
- Round shanks allow use with a wide variety of toolholding systems
- When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
- Ideal for drilling in tough, high tensile strength materials

### ⭐⭐⭐⭐⭐ good quality

good for steel but not for stainless

### ⭐⭐⭐⭐⭐ Drill America #54 cobalt drill bits (12 pack), Great value and they work well on steel
*by F***K on February 12, 2026*

These drill bits are a good value, and they can actually drill a hole through 3/16" steel. I had purchased Max Tool No. 54 drill bits, and they would not penetrate the steel plate and were useless for my project, so I bought the Drill America no. 54 drill bits and they work great. I would buy these drill bits again.

### ⭐⭐⭐⭐⭐ Nice drill bits
*by N***1 on October 19, 2025*

Needed these #60 drill bits for a project involving drilling through 304 stainless steel. And, these worked great. Only broke a few, probably due to using a hand drill, not a drill press. Oh well, price of drilling small holes in stainless!
