HSS being a "hard" material this makes the tool brittle, this is the case with all drill bits on the market. So to get the best usage out of your drill bits it's best to use cutting fluid/oil which will reduce heat build up on the tip of the drill and prevent it from losing it's hardness.
HSS drill bits are harder than normal steel thus able to drill through materials that are softer than HSS; Steel, various metals, wood etc.
