NEO TOOLS HSS-Co Cobalt Twist Drill Bits for Metal, 12.0 mm, 5-Pack (DIN 338, 135° Split Point)

Drilling through tough metals demands a bit that won't dull after a few holes. Standard high-speed steel bits often overheat and lose their edge when tackling stainless steel or cast iron. The NEO TOOLS HSS-Co 12.0 mm drill bits solve this with 5% cobalt alloyed into the steel, providing superior heat resistance and hardness for demanding metalworking tasks.

Who is it for

Professional metalworkers, machinists, and serious DIYers who regularly drill steel, stainless steel, cast iron, and non-ferrous metals. Ideal for use in workshops, fabrication shops, and maintenance departments where precision and tool life are critical.

Tips

Use cutting fluid or lubricant when drilling hard metals to extend bit life and improve hole quality. For stainless steel, reduce speed and apply steady pressure. Always secure the workpiece and wear safety glasses. Store bits in the provided case to prevent damage.
