Experience the ease and precision that our Cobalt Jobber Drill Bits HSS-Co5 bring to your workshop. Designed for both professionals and weekend DIYers, these drill bits make light work of even the toughest materials. Made from high-speed steel with cobalt, they offer outstanding durability and maintain a sharp cutting edge, ensuring smooth, accurate holes every time. Whether you're working with steel, high tensile steel (up to 1000 N/mm²), stainless steel (V2A/V4A), cast steel, cast iron, non-ferrous metals, or hard plastics, these drill bits deliver consistent performance and reliability.
What sets these bits apart is their thoughtfully engineered design. The standard helix with right-hand, ground flutes provides efficient chip removal and reduces heat build-up, which is essential for maintaining bit life under demanding conditions. The 135° split point ensures that the bit starts precisely where needed, minimizing wandering and ensuring accuracy on every drill. With a straw finish for added surface protection and manufactured to DIN 338 standards, you can be confident in the quality and performance that these bits offer.
No more frustrating starts or uneven holes—just clean, professional results. Enjoy faster, more efficient work, and spend less time troubleshooting your tools.
