Q1: What makes M35 cobalt twist drill bits better than regular high-speed steel (HSS) bits?
A: M35 cobalt drill bits contain 5% cobalt, which provides superior heat resistance, wear resistance, and edge retention. This makes them ideal for drilling tough materials like stainless steel, hardened alloys, and cast iron, especially under high-temperature and high-speed conditions.
Q2: What sizes are available for the M35 twist drill bits?
A: Our M35 cobalt twist drill bits are available in a range of sizes from 1mm to 13mm, with 1mm increments. We also offer custom sizes, including fractional and letter sizes, to meet your specific needs.
Q3: Can these drill bits handle tough materials?
A: Yes, these M35 cobalt drill bits are designed for use on tough materials such as stainless steel, alloy steel, cast iron, carbon steel, and other difficult-to-machine metals. They are engineered to provide reliable, precise drilling in high-demand industrial applications.
Q4: Are the drill bits coated or uncoated?
A: We offer both coated and uncoated options. Our coated drill bits are available with TiN (Titanium Nitride), TiAlN (Titanium Aluminum Nitride), and TiCN (Titanium Carbonitride) coatings for enhanced wear resistance, heat tolerance, and longer tool life. Uncoated versions are also available for standard applications.
