3 pcs step drill bits set

Set of 3 step drill bits in hardened HSS, covering 4mm – 12mm, 4mm – 20mm and 4mm – 32mm. The material is hardened HSS and each set comes in a double blister.

A step drill bores and gradually enlarges a hole in thin sheet metal, plastics and boards, each step matching one diameter. Electricians, ventilation installers, sheet-metal workers and body shops use it to open holes for cable glands, conduit or bolts. A set of 3 pieces limits tool changes.

Your request must state how many sets you need (quantity in pieces), the diameter range that matters most to you among 4mm – 12mm, 4mm – 20mm and 4mm – 32mm, and your destination country. The double blister packing and the content of the set are confirmed in the offer.
