What is it with supply houses anyhow? This cookie is set by GDPR Cookie Consent plugin. Carbide is a very hard material that can withstand high temperatures, so it won't dull as quickly as other types of drill bits.

Machining 304 Hot Rolled vs 304 Cold Drawn, Instructor approves cutting steel at 2000sfm. They also cut cleaner and faster than cobalt bits, making them a great choice when drilling through tough materials. How do you drill through hardened stainless steel? Titanium is a lightweight metal with a high melting point, great corrosion resistance and a very strong strength-to-weight ratio. Drilling through hardened stainless steel can be a difficult task. Are there different grades of cobalt drill bits? These drill bits are made from a steel alloy that contains about 8-10% cobalt. When comparing the two elements in terms of strength, tungsten would typically be the winner, as it has a higher melting point and tensile strength. Properties: carbide bits can resist more temperature than cobalt and HSS. Tungsten carbide is harder than cobalt, but it is not malleable. Required fields are marked *.
