    摘要: An elongated drill bit (20) has a shank (22) at one end and a working end (24) at the other. A flute portion (26) is between the working end (24) and the shank (22). The flute portion (26) is continuous with the shank (22) and the working end (24) and is generally unitarily formed with them. The flute portion (26) has at least one flute (30) with a helix angle between approximately 30° and 35°. The working end (24) has a pilot tip (36) with a cutting portion (34). A tapered web (94) is formed in the flute portion (26), a thickness (K) of the web (94) at the tip of the working end (24) is about 9% to 15% of the nominal diameter (D).

    摘要: A boiler for a steam cleaning device comprises a thermal heat store; an electrical heating element for heating the thermal heat store; a water cooling circuit comprising a water input for receiving water from a water tank and a steam output. The electrical heating element and the water cooling circuit are embedded in the thermal heat store and an outer surface of the electrical heating element is closer to an outer surface of the thermal heat store than an outer surface of the water cooling circuit.
