2.钻头类型
Bit type
1.钻头直径Diameter of the bit
1.第一字段为阿拉伯数字， 表示钻头直径，用英寸或毫米表示，前面的阿拉伯数字表示钻头外径（双芯钻头表示钻头通径），后面的阿拉伯数字表示钻头内径（非取芯钻头省略）。
如：8 1/2" × 101.6мм, 表示钻头外径为8 1/2英寸，钻头内径为 101.6mm.
The first field is expressed by digit, indicating the diameter of the bit, measured by inch or millimeter. The foregoing digit indicates the outside diameter (For the Bi-center bit it indicates draft diameter). The following digit indicates the indoor diameter (it just used in coring bit, other types cancel the item).
For example: 8 1/2” × 101.6, it indicates that the bit outside diameter is 8 1/2” and the bit indoor diameter is 101.6mm.
2.第二字段为一个英文字母， 表示钻头类型（包括冠体材料和切削齿）。
The second field is expressed by an English letter, indicating the bit type (classify with body material and cutter type).
