M35 Cobalt Drill Bits for Stainless Steel & Hard Metal

Description

M35 cobalt drill bits are high-performance HSS drill bits designed for drilling stainless steel, hardened steel, and other tough metal materials. With 5% cobalt content, they offer superior heat resistance, wear resistance, and cutting stability compared to standard HSS drill bits.

As a professional drill bits manufacturer and supplier, we provide high-quality M35 cobalt drill bits for industrial, construction, and metalworking applications.

What is M35 Cobalt Drill Bit?

M35 is a type of high speed steel (HSS) drill bit alloyed with 5% cobalt. This cobalt addition significantly improves hardness and heat resistance, making it suitable for high-temperature and heavy-duty drilling applications.

Compared with standard HSS drill bits, M35 drill bits offer:

• Higher red hardness (heat resistance)
• Longer tool life
• Better performance on stainless steel
• Reduced wear under high-speed drilling

Why M35 is Best for Stainless Steel?

Stainless steel is a hard and heat-resistant material, which makes drilling difficult using standard drill bits.

M35 cobalt drill bits solve this problem because:

• They maintain hardness at high temperatures
• They reduce cutting edge wear
• They improve drilling efficiency in tough materials

👉 That’s why M35 is widely used for stainless steel drilling in industrial environments.

Applications of M35 Cobalt Drill Bits

M35 drill bits are widely used in:

• Stainless steel fabrication
• Hardened steel drilling
• Automotive manufacturing
• Machinery processing
• Industrial maintenance

They are ideal for high-strength and high-temperature drilling conditions.

M35 vs Other HSS Drill Bit Grades

To help you choose the right material:

• HSS 4241 → basic drilling, soft materials
• HSS 4341 → general metal drilling
• HSS M2 → industrial standard steel drilling
• HSS M35 → high hardness steel & stainless steel

👉 M35 is the highest performance grade in standard HSS series.
