Be it alloyed or non-alloyed steel, iron, copper, sheet zinc, grey cast iron or bronze – with this 15-piece metal drill bit set you have all the twist drill bits required for drilling into the most diverse metals and hard plastics or Plexiglas. Owing to the cylindrical shank they can moreover be combined with all current drilling machines and cordless drill drivers.

The double-edged, right-hand cutting drill bit tip of this double-fluted metal drill bit made of high speed steel with titanium nitride coating has a maximum degree of hardness of 67 HRC and with 135° split point it is manufactured to DIN 1412C.

This renders these durable drill bits especially suitable for processing particularly hard materials and at the same time permits a substantially quicker drilling rate than with comparable drill bits having a 118° drill bit tip without split point and TiN coating. Borehole and blind hole depths of up to five times the drilling diameter are no problem using these professional HSS drill bits.

The metal drill bit set contains all drill sizes with a diameter between 1.5 and 10 mm in common increments – up until 2.5 mm even several pieces. For a better readability of the respective characteristics even after repeated use, the dimensions were stamped into the shaft of every drill bit.

The complete set is delivered in a stable plastic box which enables both the clean transportation and the suspension from a pegboard. All drill bits are firmly fitted and presorted in a fixed position, owing to an inclinable retainer they can easily be removed from the box.
