This 10-piece M35 HSS cobalt drill bit set is designed for precision drilling in demanding applications. Each bit contains 5% cobalt content, delivering high hardness, stable performance, and superior heat resistance.
The 135° point angle with cross-cutting geometry removes chips and particles efficiently, while the precisely ground surface ensures smooth chip evacuation. This combination extends tool life and reduces heat buildup during extended use.
Use these bits for drilling stainless steel and hard steel with confidence. They also perform reliably on cast iron, copper, aluminium, hard plastics, and wood, making them versatile for workshop and industrial applications.
Each bit measures 30mm in total length. The M35 material provides excellent durability across a range of materials, offering consistent performance whether you’re working with metals or harder composite materials.
For best results, use these bits with standard drill presses or hand drills. Note that impact drills are not recommended for use with this set.
Start with the 0.8mm diameter bit for precision work on fine details and small components.
