N-Durance COBALT100 HSS DIN337 Cobalt Drill Bit 10mm x 133mm (Single) – Twist Drill Bits

The N-Durance COBALT100 HSS DIN337 Cobalt Drill Bit 10mm x 133mm (Single) is expertly engineered to deliver exceptional performance and durability in demanding drilling applications. Crafted from premium high-speed steel (HSS) alloyed with cobalt, this twist drill bit is optimised for precision drilling through tough materials, maintaining sharpness and structure even in high heat.

• Diameter: 10mm
• Overall Length: 133mm
• High-speed steel (HSS) construction
• Enhanced with cobalt for increased heat resistance
• DIN337 compliant for standardised accuracy

Compared to conventional drill bits and earlier models, the N-Durance COBALT100 stands out for its robust build and longer operational lifespan. While many standard twist drill bits can struggle with hardness and rapid wear, this cobalt-infused bit consistently outperforms in both longevity and efficiency. It is particularly well-suited for professional trades and DIY enthusiasts who require precise results when working with stainless steel, cast iron, and other challenging materials.

Key Technical Advantages: The N-Durance COBALT100 HSS DIN337 Cobalt Drill Bit 10mm x 133mm (Single) benefits from a unique combination of high cobalt content and HSS, offering up to five times longer life than comparable non-cobalt bits. This translates to fewer bit changes and uninterrupted workflow, saving you time and resources in the workshop or on-site. The adherence to DIN337 standards ensures that every bit meets strict tolerances for diameter and concentricity, guaranteeing reliable and repeatable results.

Technology and Performance
Purpose-built for tough environments, the N-Durance COBALT100 features precision-ground flutes that facilitate optimal chip removal, reducing the risk of bit jamming or overheating. Its superior heat resistance allows for higher drilling speeds and efficiency, making it a valuable addition to any toolkit. Whether tackling stainless steel or abrasive alloys, this twist drill bit maintains its edge, supporting faster, cleaner holes and extended service life compared to industry norms. Rely on N-Durance’s innovation to provide performance and reliability each time you reach for your drill.
