The drills for metal are made of rapid steel ?4?4?2 and have nitride titan coating. The surface of the drill features increased hardness and reduced friction factor which considerably increases operational properties of the tool (nitride titan coating increases durability of the tool 2–2.5 times). The six-plane shank prevents turning of the drill in the chuck. The set includes the drills for metal of the most common sizes. The set is packaged in an unbreakable polypropylene case.
