HSS drill bits are drill bits made from high-speed steel. They are designed to drill into metal, wood, and plastic, and are known for their durability and resistance to heat.
Here are some characteristics of HSS drill bits:
Material
HSS drill bits are made from a hardwearing alloy steel that contains high concentrations of chromium and nickel.
Performance
HSS drill bits are resistant to the heat generated by drilling at high speeds, and are safe to use at high RPMs.
Applications
HSS drill bits are suitable for drilling into a variety of materials, including metal, wood, and plastic.
Shank.
Maintenance. HSS drill bits can be sharpened and will perform well if properly maintained. When using smaller HSS drill bits, it's important to apply light pressure to prevent them from breaking.
