Q 1. What size are these drill bits?

A. Each drill bit in this pack is Ø4.5mm in diameter.

Q 2. What materials can these drill bits cut through?

A. These bits are suitable for drilling high carbon steel and stainless steel.

Q 3. What standard are these drill bits manufactured to?

A. They are fully ground HSS Cobalt drill bits manufactured to DIN 338.

Q 4. Why choose a cobalt drill bit over a standard HSS bit?

A. The 5% Cobalt content gives increased heat hardness, which helps extend the life of the drill bit, making it better suited to tough materials such as stainless steel and high carbon steel.
