Norseman’s bits are also designed to prevent grabbing or tear-outs, making them especially easy to use for beginners.

But, despite the high breaking strength they exhibit, they’re also brittle and don’t offer much resistance to bending. Which means it’s easy to snap thinner bits with even the most innocuous of impacts. Smaller diameter drill bits tend to be easy to break, so it’s a helpful touch that Draper has doubled up on the 1.5, 2.0, and 2.5mm bits.

What does a metal or plastic drill bit look like? Toughness is paramount when drilling into metal because the heat generated can easily spell the end for cheap drill bits. Not so here, as this set from Draper sees the HSS straight shank bits coated with long-testing and tough titanium nitride. They’re likely to last longer, and they will not get lost as they come in a soft-grip plastic case which is clearly labelled, making finding bits and returning them to their correct slot a simple task.
