What Are HSS Drills?
HSS drills are cutting tools made from high-speed steel, a tool steel alloy designed to maintain hardness even at high temperatures generated during drilling operations.
Unlike standard carbon steel drills, HSS drills can withstand higher cutting speeds and temperatures without losing their cutting edge. This makes them ideal for both manual drilling machines and CNC machining centers.
Key characteristics of HSS drills include:
-
High heat resistance
-
Strong cutting edges
-
Excellent durability
-
Versatility across different materials
Because of these properties, HSS drills are widely used in industrial manufacturing and metal fabrication processes.
