HSS drill bits are suitable for relatively hard metals and woods, while cobalt is suitable for hardened metals, cast iron and stainless steel.
2. Brittleness
HSS bits are more flexible and therefore less likely to break, while cobalt bits are more brittle and fragile.
3. Heat resistance
HSS has poor heat resistance, while cobalt drill bits can work effectively at extreme temperatures.
4. Components
HSS contains steel and other elements such as chromium and vanadium, while cobalt drill bits contain 5-8% cobalt in addition to these elements.
5. Durability
HSS has poor durability, while cobalt has a longer service life under proper maintenance.
