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.
