空心鉆頭規(guī)格跟取芯鉆頭型號的區(qū)分主要由以下兩個方面:第一是空心鉆頭的直徑(傳統(tǒng)的講是外徑),第二是按取芯鉆頭的深度
空心鉆頭規(guī)格-直徑大?。?2,12.5,13,13.5,14,14.5,15,15.5,16,16.5,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40
,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,
82,83,84.,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102.,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118
,119,120
取芯鉆頭型號-鉆孔深度:25深,35深,50深,75深.100深,125深
所以針對于空心鉆頭規(guī)格及取芯鉆頭型號我們以12為例就有,12*25深,12*35深,12*50深,12*75深,12*100深,12*125深幾種,其他直徑以此類推即可。
