What Drill Bit Sizes Should an N-scaler Own?

Iuse the double headed pin vice like in the zona selection! maybe I'm more careful than the other guys but I'v never broken a bit with it! That said, its probably slower than the sprial ones. OH and Welcome to Trainboard! Sorry it took so long to get back to this thread but I was called in to work and only just got back.

 

The other day I had to install a Micro Trains coupler on the tender of a Bachmann 2-8-0 and I needed a #62 drill bit for the screw hole and a #60?? tap for the threads.

This seems like a pretty common size for N scale so you might want to include them in your purchases.

Drill size nomenclature

Please forgive the naive question from a Limey - but is there a useful site that compares the number system eg #80 with metric eg 0.14mm with American [British/Imperial] eg 0.010" or 1/64" drills.

I see how many of you use the American drill numbering system - but I cannot transfer these to European/British drill sizes.

Thanks

This should fit the bill: Drill bit sizes - Wikipedia, the free encyclopedia

 

I use drill bit sizes #60 through #80 most often...

 

At least you picked the right rail road wink:

 

I actually bit the bullet (no pun intended) and spent a lot of money on a set of Starrett pin vises. I think it was $60. It was worth it, the extra heft and precision really outshines the other pin vises I have (a really cheap one that's no good, and a Zona double ended set).

So WHERE does one get a #85 or #90 drill bit??????

 

Here you go 5pc Pack New Carbide Wire Size Drill Bits

 

We stock mini drill bits as well. I am posting because I have found they are sometimes hard to get individually.

Thanks Guys , Mike

 

Thanks for that information... I think. #85's go for $5 each and #90's for $10 each!!!

WOW!!

Tell me they're unbreakable!

 

Not quite, you have to treat them gingerly and with respect and with loving care..like you would with a beautiful woman. Then they will last you a very long time. I have had mine for almost a year and haven't broken one yet.
