What is a drill bit?

Drill bits are attachments for power tools, like handheld or industrial size drills. They generally come in different shapes or sizes and drastically reduce the manual work needed for construction, electrical or masonry applications.

What does jobber mean?

The word jobber specifies the length of the drill bit. This generally means the length of the entire drill bit itself is significantly longer for diameter it has. As an example, a mechanic drill bit will have a much shorter flute and therefore have a much smaller overall length.

What is HSS?

An acronym for High-speed steel, HSS is generally the go-to type of steel needed for drill bits due to their excellent heat resistance at high speeds. As a standard drill can spin upwards of around 500 - 700rpm, the friction can cause a substantial build-up of heat. Something which would not be wanted when working with wood and plastic.
