Compared to standard high-speed steel drill bits, the N-Durance COBALT045 offers markedly superior durability and cutting power, especially when used with hardened or stainless steels. Owing to its enhanced cobalt content, these drill bits maintain their sharpness far longer than ordinary HSS variants, reducing the need for frequent replacements. When measured against previous models, this drill bit showcases not only better heat resistance but also an improved cutting edge, allowing for more consistent results under continuous use.

Key Technical Advantages:
Technology and Performance

The N-Durance COBALT045 drill bits are innovatively constructed using premium cobalt alloy, ensuring greater resistance to heat and wear during prolonged drilling operations. This leads to a reduction in bit breakages and minimises downtime, even when tackling metals that often prove challenging for inferior products. Their precision-ground flutes ensure rapid swarf removal, significantly lowering the risk of binding and overheating during use.

Furthermore, adherence to DIN338 geometry delivers reliable accuracy and a straight drill path — crucial for applications demanding a flawless finish. The robust cobalt HSS construction also provides enhanced toughness, reducing chipping and extending the lifespan of each drill bit within the pack. Select the N-Durance COBALT045 Cobalt HSS Drill Bit DIN338 4.5mm x 78mm (Pack of 2) for consistently top-tier performance and efficiency in your drilling projects, whether you are outfitting a professional workshop or undertaking advanced home improvements.
