Engineered with 5% Cobalt (M35 grade) blended into high-speed steel, this bit is designed specifically for drilling into hard, abrasive metals that would dull standard bits.

The Krobahn HSS Cobalt Drill Bit is a premium workshop essential for tradespeople and serious DIYers who refuse to compromise on performance. While standard high-speed steel bits struggle and overheat when faced with stainless steel, Krobahn’s cobalt-infused metallurgy ensures the bit remains sharp and effective. At ECO Heat Shop, we supply the heavy-duty hardware and professional-grade tools required for precision engineering and robust metal repairs.
These bits are fully ground from a single piece of M35 alloy steel, offering exceptional strength and resistance to breakage. The high-heat resistance of the cobalt allows for faster drilling speeds without the bit losing its temper (softening). Whether you are working on automotive repairs, marine stainless steel, or industrial metalwork, Krobahn delivers the cutting power you need for a clean, accurate hole every time.
