过去,破碎钻孔系统的突出特点在于对干硬性混凝土或砖块进行钻孔作业。对于软性多孔的材料,例如极软的凝聚物、轻砖式复合材料等含有沥青和其他油性物质的材料,虽然也能完成加工作业,但不总是有效的。现在,带有新的P型中心钻头的Keil公司的259破碎钻孔系统被认为是在各种场合下都具有解决加工的实力。该系统专门的中心钻头(现已更名为S型)在硬材料上惊人的加工性能是
In the past, the salient feature of the crushing drilling system was the drilling of hard and stiff concrete or bricks. For soft porous materials, materials containing bitumen and other oily substances such as very soft agglomerates, light brick composites, although processing operations are also complete, it is not always effective. Today, Keil’s 259 Boring Drilling System with the new P-Center drill bit is considered to have the capability to solve machining on a variety of occasions. The system-specific center drill bit (now renamed the S-type) on the hard material amazing processing performance
