Due to the 8% of cobalt, M42 is harder and more stable. M42 cobalt drill bit has a hardness of 68-70 HRC and a higher melting point of 2853 oF. M35 is a type of cobalt drill bit with mixing of 8% of cobalt and HSS. Hence it can be used in a wide range than a regular drill bit. Due to the 5% cobalt, its physical properties and chemical properties are varied. Therefore, M35 cobalt drill bits are used to drill many hard materials. Hence, M35 Cobalt drill bits are more heat resistant. M35 Cobalt drill bit has a hardness of 65-67 HRC and a higher melting point of 2723 oF. M35 is a type of cobalt drill bit with mixing of 5% of cobalt and HSS. What Is Better, M35 or M42 Drill Bit? What Is M 35 Drill Bit?.What are the Differences Between M35 Vs.Effortlessly grab the set in one hand like a travel coffee mug, leave it in your truck's cup holder while you're on your way to work, or hang it on your belt when all hands are on deck. The shatterproof, water-resistant case fits easily anywhere you need it. This drill bit set comes in a unique round drill index that combines form and function in a beautifully designed, easy-to-carry drill set. A gold oxide coating acts as a lubricant and provides wear resistance, and the round shank fits most drill chucks. Cobalt steel provides longer life compared to high speed steel drill bits and maintains the toughness and hardness of the tool at high drilling temperatures. Cobalt drill bits have a self-centering 135 degree cross point penetrates hard material without a pilot hole and produces smaller chips that reduce clogging compared to a 118 degree point. They are manufactured to Aerospace Standard 907 and have a high red hardness, making speeds up to 30% higher than conventional M2 high speed steel.
