• Material: Cobalt-High Speed Steel (HSS)
• Standard: DIN338 compliant
• Quantity: Supplied as a single unit

Compared to standard HSS drill bits, the COBALT085 sets itself apart by boasting enhanced heat and wear resistance, credit to its high cobalt content construction. This makes it particularly well-suited for repetitive drilling in tougher metals, such as stainless steel and cast iron, where conventional drill bits might fail or wear prematurely. Users transitioning from previous models will notice the marked improvement in longevity and consistent precision.

Key Technical Advantages:
The N-Durance COBALT085 combines advanced metallurgy with precision manufacturing to deliver superior drilling results. Its robust HSS construction, enriched with cobalt, minimises wear and delivers up to 50% longer service life compared to standard twist drill bits. The DIN338 compliance ensures uniformity and compatibility with a wide range of drilling equipment, while the optimised 8.5mm diameter and 115mm length provide versatility for various drilling tasks.

Technology and Performance
The use of cobalt-alloyed high-speed steel enhances both performance and safety, allowing for stable and accurate penetration of tough materials without overheating or chipping. This twist drill bit’s engineering guarantees exceptionally clean cuts and reduced bit wandering, even under strenuous workloads. Whether included in a professional workshop or a home tool kit, the N-Durance COBALT085 delivers reliable results and stands as a new benchmark in the twist drill bits category.
