    • The invention relates to an interchangeable holder (1) for hollow drills, comprising a support element (4) for receiving a base end (11) of a drill rod (10) of the hollow drill on a front face, and a holding device (12) for a handle of the support element (4) on associated recesses (15) that are configured in the wall of the drill rod (10) on its base end (11). The aim of the invention is to provide a universal interchangeable holder on which drill rods with different diameters can be mounted. To this end, the support element (4) has a front-face annular rest zone (9) that receives drill rods (10; 10'; 10 ) with different diameters. A locking device (24), together with the holding device (12), is effective across the width of the annular rest zone (9) in order to maintain the respective drill rod (10; 10'; 10 ) placed on the rest zone (9) and held by the holding device (12) locked in a center position.

    • A drill bit for boring concrete, capable of (1) supplying cooling liquid to the tip of the bit without fail, (2) facilitating discharge of core penetrated into the body, and (3) preventing the operating speed from being lowered by the wear of the inner circumference of the bit. For this purpose, (1) a path for cooling liquid communicating with the pointed end of the bit tip is formed within the peripheral plate of the drill body; (2) a slope is formed at the inner deep portion within the drill body, and a port for discharging the core is formed in the peripheral plate of the body; and (3) an inversely tapered face is formed on the inner circumference of the bit tip.
    • 一种用于钻孔混凝土的钻头,能够(1)将冷却液提供给钻头的尖端,(2)便于穿透到体内的芯体的排出,以及(3)防止工作速度被磨损降低 的位的内圆周。 为此,(1)在钻头体的周边板内形成有与钻头尖端连通的冷却液的路径, (2)在钻体内部的深部形成有斜面,在本体的周边板上形成有用于排出芯的端口, (3)在钻头尖端的内周上形成有倒锥面。

    • A core bit provided with a tube (2) having an opening (21) in an axial direction and a plurality of tips (3) fixed to the opening (21) of the tube (2). Each tip (3) contains an abrasive grain layer (31). The grain layer (31) contains diamond abrasive grains and a binder which binds the diamond abrasive grains together. The diamond abrasive grains contains 0.03 wt.% or less inclusion. The inclusion contains iron and nickel as its main components. The binder contains 0.1 wt.% or more but 2.0 wt.% or less graphite. The core bit takes a short time in drilling, that is, has a high cutting speed and a good sharpness, and is excellent in durability and long in service life. The core bit is suitable for drilling a hole in a concrete structure.
    • 具有在轴向上具有开口(21)的管(2)的芯部和固定到所述管(2)的开口(21)的多个尖端(3)。 每个尖端(3)包含磨粒层(31)。 晶粒层(31)含有金刚石磨粒和将金刚石磨粒结合在一起的粘合剂。 金刚石磨粒含有0.03重量%以下的夹杂物。 包含铁和镍为主要成分。 粘合剂含有0.1重量%以上但2.0重量%以下的石墨。 核心钻头需要很短的时间,即具有高切削速度和高锐度,并且耐久性和使用寿命长。 芯钻头适用于在混凝土结构中钻孔。
