I have new zerk fittings for my Elephant poly bronze rear bushings. They have upgraded the size from M5 .8 threads to a M6 .75. They had issues with them sheering off....like me. What size drill do I use? Or should I just use my new HF tap in the existing threaded hole? I have a drill bit spec for a M6 1.00 thread of 13/64. Is that the same size for M6 .75?

Does your tap set not have drill bit sizes stamped on them? They are kind of small to read, but the ones we have here are all stamped with specs.

They are labeled with size/pitch and freakin CHINA. My Crafsman set has a booklet with chart for appropriate drill bit size, but kit does not have tap I need and sears didn't either. I could order though. Thats why the Harbor Freight. |

It should be fine to use the smaller bit. You are only tapping 1/8 inches deep, so it should be ok. If it was 1/4 or more...you may have an issue. Just go slow and feel it as you go, as soon as you feel it stop, turn it back a 1/4 turn to unload the tap and continue...back and forth. Rich |
