Klein Tools为专业电工设计了一套Impact Power Bits。所有钻头均采用高强度额定S2钢和彩色编码，便于识别。1-1 / 4英寸（6.4毫米）长的驱动器位比标准的1英寸（25.4毫米）钻头更容易抓握。刀架和螺母驱动器具有坚固的磁铁，并且设计得更长，因此它们很容易进入接线盒。螺母驱动器的六角凹槽上的最小倒角增加了螺母和驱动器之间的表面接触，以获得更好的性能。所有26件均贴合在一个耐用，抗冲击的表壳中，配有钢制铰链，一个保持关闭的闩锁和一个用于松散位的隐藏隔层。

Klein Tools has designed a set of Impact Power Bits for the professional electrician. All the bits are made of high-impact rated S2 steel and color coded for easy identification. The 1-1/4-Inch (6.4 mm)long driver bits are easier to grip than a standard 1-Inch (25.4 mm)bit. The bit holder and nut drivers have strong magnets, and are also designed longer so they reach easily into junction boxes. Minimal chamfering on the nut drivers’ hex pockets increases surface contact between the nut and driver for better performance. All 26 pieces fit snugly in a durable, impact-resistant case featuring steel hinges, a stay-shut latch, and a hidden compartment for loose bits.
