    In an ice drill (1) having a one-piece light metal base body (2), which light metal base body (2) has a helical part (3) and a cutting part (4) adjoining the helical part (3), it is proposed that the cutting part (4) has at least one Tungsten carbide cutting plate (11, 12, 13) which is removably attached to the light metal base body (2), that the coil part (3) at least a first coil (6) and a second coil (7), each having a substantially trapezoidal or have rectangular cross-section, and that the first coil (6) and the second coil (7) over the entire length of the coil part (3) are arranged such that the first coil (6) in the cutting part (4) as the first carbide cutting plate holder (9 ) of the cutting part (4) is formed, and in that the second helix (7) is formed in the cutting part (4) as a second carbide cutting plate holder (10) of the cutting part (4), that on the first Hartmet allschneidplatten- holder (9) a first hard metal cutting plate (12) is fixed, and in that on the second carbide cutting plate holder (10), one of the first hard metal cutting plate (12) different, second carbide cutting plate (13) is fixed, and that the first and the second hard metal cutting plate (12, 13) are arranged spaced apart from one another for cutting a merely annular region.

    (54) ICE DRILL (57) In an ice drill (1) with a one-piece light metal base (2), which
    Light metal base body (2) has a helical part (3) and a cutting part (4) adjoining the helical part (3), it is proposed that the cutting part (4) have at least one hard metal cutting plate (11, 12, 13) which is exchangeable on the
    Light metal base body (2) is attached such that the coil part (3) has at least a first coil (6) and a second coil (7), each of which has an essentially trapezoidal or rectangular cross section, and that the first coil (6) and the second helix (7) are arranged along the entire length of the helical part (3), that the first helix (6) in the cutting part (4) is designed as the first hard metal cutting plate holder (9) of the cutting part (4), and that the second helix (7) is formed in the cutting part (4) as a second hard metal cutting plate holder (10) of the cutting part (4), that a first hard metal cutting plate (12) is fastened to the first hard metal cutting plate holder (9) and that on the second hard metal cutting plate holder ( 10) a second hard metal cutting plate (13) which is different from the first hard metal cutting plate (12) is fastened, and that the first and second hard metal cutting plates (12, 13) for cutting a only annular areas are spaced from each other.
