Drill with Precision and Power

Crafted from 5% cobalt high-speed steel, these cobalt drill bits provide excellent wear resistance and heat stability, staying sharp and reliable even during high-intensity work. This extends the lifespan of the bits and improves overall work efficiency.

The 135° split point optimizes cutting force distribution, reducing hole deviation and surface roughness. The twisted design of the metal drill bit speeds up chip discharge , avoiding clogging and reducing wear on the drill bits.

This cobalt drill bit set includes up to 29 different sizes, ideal for a wide range of applications from home use to heavy-duty industrial tasks. Whether for precision work or tough jobs, you'll find the right drill bit for your needs.

Our wear-proof drill bit for metal drilling features strong penetration power, making them suitable for drilling through a variety of materials, including steel, stainless steel, aluminum, copper, wood, and plastic.

When using the twist drill for drilling, ensure the m35 cobalt drill bit set is perpendicular to the material's surface, maintaining a 90° angle. This helps improve drilling accuracy and quality, while minimizing the risk of bit misalignment or damage.
