HSS bits are hardwearing and heat resistant. The large concentrations of chrome and nickel in stainless steel ensure that HSS bits are super strong and durable. HSS drill bits are capable of safely drilling through hardwood, some metals and plastic. They’re safe to operate at high speeds (RPM) and provide long-lasting performance – as long as they are maintained.

Over time, HSS drill bits can become blunt and need to be sharpened, which demands specialist tools that aren’t always available. If you’re using HSS drill bits for long periods or at high RPMs, you may need to use cutting fluid to keep the bit cool.
