Frequently Asked Questions
What materials can this cobalt drill bit cut?
Our cobalt drill bits handle stainless steel, cast iron, hardened steel, alloy steels, aluminum, copper, and more.
What speed should I use when drilling metal?
Use our Speeds & Feeds Calculator to set the correct RPM. Running too fast will overheat the bit; slower speeds preserve sharpness.
Can cobalt drill bits be resharpened?
Yes — cobalt drill bits can be resharpened, giving you long-term value.
How is cobalt different from standard HSS?
Cobalt (M35, 5%) withstands higher heat and stays sharper longer, making it ideal for harder metals compared to standard high-speed steel.
Do I need cutting paste when drilling metal?
We recommend TTP CUT-IT cutting paste for smoother drilling, cooler operation, and longer tool life.

1mm Drill Bit for Metal – Precision in Every Cut
Discover our 1mm drill bit for metal, crafted for fine, accurate drilling in steel, aluminum, and more. Built with a 118° tip angle for clean starts. Ideal for delicate precision tasks.
Built for Accuracy in Small-Scale Metal Drilling
If you're working on precision projects—such as electronics, model-making, or jewelry—the 1mm drill bit for metalis a must-have tool in your kit. Small but mighty, this bit is engineered to deliver exceptional accuracy on thin and delicate metals.
Unlike most of our cobalt bits, this size features a 118° point angle. Why does that matter? Because the shallower angle is perfect for thin material. It reduces walking and improves control, especially when you don’t have a pilot hole. As a result, you get cleaner entry points with minimal surface damage.
Made from M35 Cobalt for Superior Performance
Despite its tiny size, this bit means business. It’s made from M35 high-speed cobalt steel, which holds up brilliantly under heat and pressure. Even when drilling stainless steel, it won’t dull out quickly like standard HSS bits.
You'll find this bit useful for:
Sheet metal and aluminum
Mild steel or stainless steel
Copper, brass, and soft alloys
Metal-faced plastics
When you're drilling several holes in tougher materials, heat builds up fast. To keep things cool and extend tool life, we always recommend using TTP CUT-IT metal cutting paste.
Use the Right Speed Every Time
Getting the right RPM is crucial—especially with a small bit like this. Our free Speeds & Feeds Calculator helps you choose the ideal speed and feed rate based on material and drill size. With this tool, you’ll avoid overheating and extend the lifespan of every drill bit.
Trusted by Professionals — Backed by Our Guarantee
Still not sure if this is the right bit for you? Check out our real-world customer reviews (PDF) and see what others are saying.
Like every drill bit we sell, the 1mm cobalt version is backed by our money-back guarantee. If it doesn’t outperform your current bits, we’ll refund your purchase—no questions asked.
Conclusion: Ideal for Precision, Built to Last
In summary, the 1mm drill bit for metal is the ideal solution for those delicate drilling tasks that demand accuracy and control. Whether you’re building, repairing, or customizing, this bit ensures your work starts right.
