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；而依抿市售之标准钻头所选定的，在使用钻头的情精度有很大的影响，所以使用本表之钻孔径，若有不当之处，应视实际壮况适当的变更钻头直径，本表是依据2级牙最大最小最大最小G4-G6G7-G8G9M1.0*0.250.750.7850.729M12*1.011.0011.15310.917M1.0*0.250.860.88-M1.1*0.250.850.8850.829M12*0.511.5011.52011.400M1.1*0.250.960.98-M1.2*0.250.950.9850.929M14*1.512.5012.67612.376M1.2*0.251.061.08-M1.4*0.301.001.1421.075M14*1.013.0013.15312.917M1.4*0.301.241.25-M1.6*0.351.251.3211.221M15*1.513.5013.67613.376M1.6*0.351.411.43-M1.7*0.351.351.4211.321M15*1.014.0014.15313.917M1.7*0.351.511.53-M1.8*0.351.451.5211.421M16.1.514.5014.67614.376M1.8*0.351.611.63-M2.0*0.401.601.6791.567M16*1.015.0015.15314.917M2.0*0.401.781.80-M2.2*0.451.751.8381.713M17*1.515.5015.67615.376M2.2*0.451.951.98-M2.3*0.401.901.9791.867M17*1.016.0016.15315.917M2.3*0.402.082.10-M2.5*0.452.102.1382.013M18*2.016.0016.21015.835M2.5*0.452.252.28-M2.6*0.452.202.2382.113M18*1.516.5016.67616.976M2.6*0.452.352.38-M3.0*0.502.502.5992.459M18*1.017.0017.15316.917M3.0*0.502.732.75-M3.0*0.602.402.4402.280M20*2.018.0018.21017.835M3.5*0.603.173.20-M3.5*0.602.903.0102.850M20*1.518.5018.67618.376M4.0*0.703.623.653.69M4.0*0.703.303.4223.242M20*1.019.0019.15318.917M5.0*0.804.564.604.64M4.0*0.753.253.3263.106M22*2.020.0020.21019.835M6.0*1.005.455.505.55M4.5*0.753.803.8783.688M22*1.520.5020.67620.376M7.0*1.006.456.506.55M5.0*0.804.204.3344.134M22*1.021.0021.15320.917M8.0*1.257.317.387.44M5.0*0.904.104.1703.930M24*2.022.0022.21021.835M10*1.509.189.259.32M6.0*1.005.005.1534.917M24*1.522.5022.67622.376M10*1.259.319.389.44M7.0*1.006.006.1535.917M24*1.023.0023.15322.917M12*1.7511.0411.1211.21M8.0*1.256.806.9126.647M25*2.023.0023.21022.835M12*1.2511.3111.3811.44M9.0*1.257.807.9127.647M25*1.523.5023.67623.376M10*1.508.508.6768.376M25*1.024.0024.15323.917M11*1.509.509.6769.376M26*1.524.5024.67624.376M12*1.7510.3010.44110.160M27*2.025.0025.21024.835M14*2.0012.0012.21011.835M27*1.525.5025.67625.376M16*2.0014.0014.21013.835M27*1.026.0026.15325.917M18*2.5015.5015.74415.294M28*2.026.0026.21025.835M20*2.5017.5017.74417.294M28*1.526.5026.67626.376M22*2.5019.5019.74419.294M28*1.027.0027.15326.917M24*3.0021.0021.25220.752M30*3.027.0027.15226.752最大最小M27*3.0024.0024.25223.752M30*2.028.0028.21027.835No 1-64(1.854)1.551.5821.425M30*3.5026.5026.77126.211M30*1.528.5028.67628.376No 2-56(2.184)1.801.8711.695M30*1.029.0029.15328.917No 3-48(2.515)2.102.1461.941M32*2.030.0030.21029.835No 4-40(2.845)2.302.3852.157M32*1.530.5030.67630.376No 5-40(3.175)2.602.6972.487最大最小M33*1.030.0030.25229.752No 6-32(3.505)2.802.8952.642M1.0*0.20.800.8210.783M33*2.031.0031.21030.835No 8-32(4.166)3.403.5303.302M1.1*0.20.900.9210.883M33*1.531.5031.67631.376No 10-24(4.826)3.903.9623.683M1.2*0.21.001.0210.983M35*1.533.5033.67633.376No 12-24(5.486)4.504.5974.344M1.4*0.21.201.2211.183M36*3.033.0033.25232.752 1/4 - 205.105.2574.979M1.6*0.21.401.4211.383M36*2.034.0034.21033.835 5/16 - 186.606.7316.401M1.7*0.21.451.5001.460M36*1.534.5034.67634.376 3/8 - 168.008.1537.798M1.8*0.21.601.6211.583 7/16 - 149.409.5509.144M2.0*0.251.751.7851.729 1/2 - 1310.8011.02310.592M2.2*0.251.951.9851.929 9/16 - 1212.2012.44611.989M2.3*0.252.052.6102.001 5/8 - 1113.6012.86813.386M2.5*0.352.202.2212.121最大最小 3/4 - 1016.5018.84016.307M2.6*0.352.202.2462.186No 0-80(1.524)1.251.3051.182 7/8 - 919.5019.76119.177M3.0*0.352.702.7212.621No 1-72(1.854)1.551.6121.474 1 - 822.2022.60621.971M3.5*0.353.203.2213.121No 2-64(2.184)1.851.9121.756 1-1/8 - 725.0025.34924.638M4.0*0.53.503.5993.459No 3-58(2.515)2.102.1972.025 1-1/4 - 728.2028.52427.813M4.5*0.54.004.0993.959No 4-48(2.845)2.402.4582.271 1-3/8 - 630.8031.11530.353M5.0*0.54.504.5994.459No 5-44(3.175)2.702.7402.551 1-1/2 - 634.0034.29033.528M5.5*0.55.005.0994.959No 6-40(3.506)2.903.0222.820 1-3/4 - 539.5039.82738.964M6.0*0.755.305.3785.188No 8-36(4.166)3.503.6063.4042 - 4-1/245.2045.59344.679M6.0*0.55.505.5505.400No 10-32(4.826)4.104.1653.963M7.0*0.756.306.3786.188No 12-28(5.846)4.604.7244.496M7.0*0.56.506.5506.4001/4 - 285.505.5885.360M8.0*1.07.007.1536.9175/16 - 246.907.0356.782M8.0*0.757.307.3787.1883/8 - 248.508.6368.382最大最小M8.0*0.57.507.5207.4007/16 - 209.9010.0339.729No 12 - 324.7004.8264.623M9.0*1.08.008.1537.9171/2 - 2011.5011.60711.3291/4 - 325.6005.6905.486M9.0*0.758.308.3788.1889/16 - 1812.9013.08112.7515/16 - 327.1007.2647.087M10*1.258.808.9128.6475/8 - 1814.5014.68114.3513/8 - 328.7008.8658.661M10*1.09.009.1538.9173/4 - 1617.5017.67817.3237/16 - 2810.20010.33810.135M10*0.759.309.3789.1887/8 - 1420.5020.57520.2701/2 - 2811.80011.93811.709M10*0.59.509.5209.4001 - 1223.2023.57123.1149/16 - 2413.20013.38613.132M11*1.010.0010.1538.9171-1/8 - 1226.5026.74626.2895/8 - 2414.80014.98614.732M11*0.7510.3010.37810.1881-1/4 - 1229.5029.92129.4643/4 - 2017.80017.95817.678M12*1.5010.5010.67610.3761-3/8 - 1232.8033.09632.6397/8 - 2021.00021.13320.853M12*1.2510.8010.91210.6471-1/2 - 1236.0036.27135.8141 - 2024.00024.30824.028美 制 特 细 螺 纹螺丝攻牙钻孔径和滚造径对照表公 制 细 螺 纹美 制 细 螺 纹公制迫牙丝攻钻孔径
