    The Karnasch Professional step drill made of HSS-XE steel and BLUE DUR coating and spiral fluted with split point

    Karnasch STEP DRILLS are designed to drill perfectly round holes in sheet metals of an thickness up to 5 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 4 - 12 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.

    HSS-XE steel + BLUE-DUR coating

    Made of high-alloyed special steel XE for considerably longer service life than HSS-Steel. BLUE-DUR coating for a further substantial increase in service life also when machining dry (no/little cooling).

    3-Flat shank for:

    • Excellent torque transmission
    • No slippage in the drill chuck
    • This results to superior cutting output

    All step drills and sheets drills are available in the patented BLUE-DUR-coating or TiN-GOLD-coating. Coatings significantly increase the service life. Strongly recommended for difficult materials such as stainless steels and if drilling without coolants.

    All step drills and sheet drills comes lasered with diameters in the spiral.

    All step drills and sheet drills are made of high-alloy steel HSS-XE for a hardness up to 68 HRC. This results in high wear resistance and service life.

    • Smooth cutting behavior
    • No sticking in the material
    • Low cutting forces
    • Less burrs on the work piece
    • Longer service life
