螺纹打底孔用钻头直径尺寸表
螺纹打底孔用钻头直径尺寸表攻螺纹前底孔直径和套螺纹前螺杆直径尺寸的确定(一) 普通螺纹钻底孔用钻头直径计算公式:P<1mm时，D0=d-PP>1mm时，D0=d-(1~1.1)P式中 P——螺距(mm)D0——攻螺纹前钻头直径(mm)d——螺纹公称直径(mm)工厂里的经验公式:钻孔直径,0.85*螺丝直径(取近式值)，比如:用M8*0.85=6.8M8一般用6.8的钻头就行，当然可以加大十几个司，这样好攻牙点，用7的钻头钻OK的。

螺纹孔参照表
螺纹攻牙钻孔径和滚造径对照表
本表所推选之钻头孔径，是针对攻牙加工时，能够很容易的了解钻孔直径；而依据市售之标准钻头所选定的。
在使用钻头的情况下，由于钻头的形状及尺寸、精度、被钻孔之材质等，对于所钻孔的尺寸、精度有很大的影响，所以使用本表之钻孔径，若有不
注：迫牙丝攻之钻孔径，在上表所列之数
值，由于被加工 材料之材质、硬度、形状
、尺寸等之影响，多少会有所变动，因此
于参考上表之同时，亦请增减若干。
当之处，应视实际状况适当的变更钻头直径。
本表是依据2级牙制订。
