These bits are perfect for heavy-duty drilling jobs in an industrial setting. The cobalt design ensures long-lasting performance and precision. Plus, the metric measurement markings make it easy to ensure accuracy.
Pros
The only downside is that they are a bit pricier compared to standard drill bits.
Cons
Overall, a great investment for any industrial and scientific workplace.
Drill bits are sharp and work well on brass. I use these drill bits in my watch repair shop. Having worked well with brass I'm sure they will work just as well with other soft metals and plastics.
Pros
Material: high-speed steel, cobalt; Flute Length: 43 mm / 1.7 in.
