Javelin Ice Black Bronze (Cobalt) Drill Bits 1.0mm–7.5mm – Clean Precision for Tough Materials
The Javelin Ice Black Bronze (Cobalt) Drill Bits 1.0mm–7.5mm are precision-ground for high-performance drilling in hard materials. Designed with cobalt alloy and a black bronze finish, these bits deliver superior durability, clean cuts, and reduced friction even under demanding conditions.
Ideal for stainless steel, alloyed metals, and cast iron, this range of cobalt drill bits is perfect for workshops, fabrication, and mechanical repairs. The cobalt-enriched HSS material resists heat and wear, keeping each bit sharp and efficient through multiple uses.
With sizes from 1.0mm to 7.5mm, this set covers a broad range of precision-drilling needs. Whether you’re doing layout work, pilot holes, or detailed fabrication, you’ll get consistent performance. The 135° split point prevents walking and ensures fast, accurate starts—no need to pre-punch the surface.
Fully ground flutes improve chip evacuation and reduce resistance. This means the bits cut faster and straighter while generating less heat. Because of the rigid design, there’s also minimal vibration, which protects both your material and your tool.
To get the best results, pair these bits with the right speed setting and cutting oil. You’ll also find more drilling and cutting tools to match your setup and expand your tooling system.
