We are offering here the various types of Twist
Drills that are a metal rod of a specific diameter that has two, three or four
spiral flutes running most of its length. Two-flute drills are for primary
drilling, whereas three- and four-flute drills are only for enlarging cast or
punched holes in a production situation. It is a drill having deep helical
grooves extending from the point to the smooth portion of the shank. The
offered Twist Drills are the most widely used of all drill bit types; they will
cut anything from wood and plastic to steel and concrete.
