    资源描述:

    1、本表所推选钻头孔径,是针对攻牙加工时,能够很容易的了解钻头直径,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,精度有很大影响,所以使用本表之钻孔径,若有不当之处,应实际状况适当的变更钻头直径,本表依据2级牙制订。公 制 粗 螺 纹规格标准径2级牙钻孔径最大最小M1.00.250.750.7850.729M1.10.250.850.8850.829M1.20.250.950.9850.929M1.40.31.101.1421.075M1.60.351.251.3211.221M1.70.351.351.4211.321M1.80.
