    The Karnasch Professional step drill made of HSS-XE steel and straight fluted with split point

    Karnasch STEP DRILLS are designed to drill perfectly round holes in sheet metals of an thickness up to 4 mm. The transition from one step to the next perfectly deburrs the previously drilled hole. Step drills are therefore a drilling and deburring tool combination.

    This versatile tool combines 9 different drills with diameters of 12 - 20 mm. The radius transition simultaneously bezels or deburrs the bore holes.

    The drills are axial-radially relief grounded and can be resharpened at the tooth face.
