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 are HSS and HSS-G?
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. The HSS-G drills bits are additionally ground at the tip and along with their flutes. HSS-G drill bits are ideal for high-performance, professional application and are ideal for drilling into an alloy and non-alloy steel, non-ferrous metals, grey cast iron and malleable iron, sintered iron.
