Hss Drills
The HSS drill bit, a high speed steel bit, comes in many sizes, as well as shapes and functionalities. Usually, the shape for most bits is the twist form. The front edges cut the material while the spirals remove the debris from the hole. Sizes of bits can come as small as .8th millimeter to as high as over 12 millimeters. Drill bits are normally made of metal alloys and are designed for a specific task. Carbon and high carbon types of bits are named thus, because they are made with a high level of carbon content.
