FAQs:

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.

What sizes are included in the set?
The set includes 5 drill bits:
• A225BS1 / Size: BS1 / Length: 1 1/2"
• A225BS2 / Size: BS2 / Length: 1 3/4"
• A225BS3 / Size: BS3 / Length: 2"
• A225BS4 / Size: BS4 / Length: 2 1/4"
• A225BS5 / Size: BS5 / Length: 2 1/2"

Can these drill bits drill into metal?
Yes, these drill bits are suitable for most drilling applications including drilling in metal.

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.

Is this set suitable for domestic use?
Yes - this is a great multi-purpose drill bit set for domestic use, however, better performance can be achieved in a professional application.
