CYLINDRICAL TWIST DRILLS WITH STEPPED GEOMETRY

The special step drill geometry (ø ≥ 3 mm) allows for extremely precise holes in size and perfectly circular in shape. Ideal for manual use in operations requiring excellent precision, particularly on thin sheets, aluminium profiles, etc.

The STEP+ drill is 30% faster compared to a traditional twist drill: the hole starting phase, facilitated by the reduced diameter of the centring tip, is extremely fast. The hole is then quickly enlarged as the step diameters increase.

Made from high-quality HSS AISI M2 steel, the STEP+ drill ensures consistent performance and a prolonged service life even under intensive use conditions. Ideal for drilling alloyed and highly alloyed steels with R ≤ 900 N/mm², stainless steel, iron, aluminium, metals in general, plastics and wood.

The stepped geometry optimally combines maximum drilling speed with high ease of use: indeed, the STEP+ never “tears”, the hole is made smoothly without generating excessive torque.

The split point on the centring tip also guarantees easy centring even on curved and difficult surfaces such as tubes and does not require pre-drilling or centre punching.

STEP+ is also extremely practical for enlarging pre-existing holes and is effective on various solid materials such as plastic and wood.
