Tvardy 2 mm HSS M35 Cobalt Metal Drill Bit

The Tvardy 2 mm HSS M35 Cobalt Metal Drill Bit is a precision-engineered cutting tool designed for demanding drilling applications in hard and alloyed metals. Manufactured from high-grade HSS M35 high-speed steel containing cobalt, this drill bit offers superior thermal resistance and structural integrity during intensive use. It is specifically engineered to maintain sharpness and cutting efficiency when working with difficult materials, making it a reliable addition to any professional workshop or toolkit.

Advantages

This cobalt metal drill bit provides exceptional durability and wear resistance compared to standard high-speed steel alternatives. The inclusion of cobalt in the HSS M35 alloy allows the tool to withstand high temperatures generated during continuous drilling operations without losing its cutting edge. The 2 mm diameter enables precise hole creation in tough workpieces, ensuring clean entry and reduced risk of bit deflection. Its robust construction minimizes breakage, leading to extended tool life and consistent performance across multiple drilling cycles.

Suitable for

• Drilling 2 mm holes in hard metals and alloyed steels
• Working with cast iron and other rigid ferrous materials
• Professional metalworking and mechanical workshop tasks
• Precision engineering and fabrication projects requiring strict accuracy

When it may not be suitable

This drill bit is not optimized for drilling into soft materials such as wood, plastics, or non-ferrous metals like soft aluminum, where standard bits or specialized geometry might perform better. Additionally, it is not intended for masonry, concrete, or stone drilling applications.

Key specifications

• Diameter: 2 mm
• Material: HSS M35 high-speed steel with cobalt
• Application: Hard metals, alloyed steels, and cast iron

How to use

Select a suitable rotary drill or drill press capable of accepting a 2 mm bit shank. Secure the workpiece firmly to prevent movement during operation. Align the drill bit perpendicular to the surface and apply steady, moderate pressure while maintaining an appropriate rotation speed. The use of a suitable cutting fluid or lubricant is recommended during metal drilling to dissipate heat, reduce friction, and further prolong the lifespan of the drill bit. Avoid excessive lateral pressure to prevent snapping the small diameter shaft.

What to consider before purchase

• Verify that a 2 mm hole diameter matches your project requirements
• Ensure your drilling equipment is compatible with small diameter straight shank bits
• Confirm the material you intend to drill falls within hard metals, alloyed steels, or cast iron categories

For optimal performance and safety, always wear appropriate eye protection, secure your workpiece properly, and use cutting lubricant to manage operational heat when drilling hard metals.
