TOOLPAK Cobalt Ground Jobber Drill Bit, 2 Pack - 4mm x 75mm

The TOOLPAK Cobalt Ground Jobber Drill Bit Set delivers exceptional performance for drilling through the toughest metals, making it an essential tool for engineers, metalworkers, and demanding DIY projects. These professional-quality drill bits are crafted from M35 (5% Cobalt) High Speed Steel, a premium material renowned for its heat and wear resistance.

Cobalt alloy reduces friction and heat build-up significantly during drilling, extending the tool's working life and allowing it to maintain its cutting edge even under high-temperature conditions. This makes them perfect for drilling into very hard and dense materials such as stainless steels, high tensile steels, and cast iron. The bits are fully ground for precise cutting action and superior chip removal.

A key feature is the 135-degree split point tip, designed to provide easy starting without skidding or walking across the material's surface. This ensures accurate hole placement and reduces the need for centre punching on many applications. Manufactured to the stringent DIN338 standard, you are assured of consistent quality, dimensional accuracy, and reliable performance in every drill bit.

This versatile 2-pack offers great value, providing you with a ready supply for your workshop. Whether you are working on automotive repairs, fabricating metal structures, or undertaking precision engineering tasks, these cobalt drill bits offer the durability and cutting power needed to complete the job efficiently and cleanly.
