What is a HSS drill bit?
HSS drill bits, an acronym for high speed steel drill bits are extremely hardwearing and particularly well designed for drilling into metal surfaces, as they are much more resistant to the heat generated from the fast speed operation. The front edges cut the material, whilst the spirals remove debris from the hole.
Can you drill into fiberglass resin?
