Cobalt Drill Bit

Cobalt Drill Bits — Premium Metal‑Drilling Bits for Professionals & Workshops

The Cobalt Drill Bit collection features high‑performance drill bits designed to penetrate tough metals such as stainless steel, cast iron, alloy steel, and other hard materials. Made with cobalt‑enhanced high‑speed steel (HSS), these bits deliver superior heat resistance, durability, and precision — making them ideal for heavy‑duty drilling applications in fabrication, construction, and industrial workflows.

Whether you’re a professional machinist, metalworker, welder, or serious DIYer, cobalt bits offer extended bit life and reliable performance when standard bits wear down too quickly. These bits stay sharper longer and withstand high RPM and heat, which improves accuracy and efficiency on the job.

What’s Included in This Collection

• Cobalt Twist Drill Bits — Standard form for general metal drilling.
• Jobber Length Bits — Versatile bits for through‑and‑through holes.

Frequently Asked Questions (FAQs)

Q: What are cobalt drill bits used for?
A: Cobalt drill bits are used for drilling hard metals like stainless steel, cast iron, and high‑strength alloys where standard high‑speed steel bits would wear out or dull quickly.

Q: What makes cobalt bits superior to regular HSS bits?
A: Cobalt drill bits contain a percentage of cobalt alloy, which increases heat resistance and hardness, allowing them to drill harder materials with less wear and a longer service life.

Q: Can cobalt bits be used on wood or soft metals?
A: Yes — but they are best optimized for metalworking. For woodworking and softer materials, standard high‑speed steel bits or wood bits are often more cost‑effective.

Q: How do I care for cobalt drill bits?
A: To maximize life, use the correct speed and feed for the material, apply cutting fluid when drilling metals, and keep bits sharp and clean between uses.
