also to detail a nscale engine with BLMAs grab irons the #80 drill is too big. to detail a Z scale engine the holes are looking way too big, are there any smaller drills available ? if so, where ? thank you for your help.
I just googled around and did not find any bits for sale smaller than #80. I did find some websites that said that bits smaller than #80 were available as specialty items, but no other information was given. I think you need to know what specialty they are used in, then you could search. Perhaps micro-electronics or some medical use? Aviation? I couldn't find them. [edit] diamond drills go down to .001 inches; that's a scale .16 inches in N scale; .22 inches in Z scale. [ January 07, 2006, 05:37 PM: Message edited by: sapacif ]
Spendy, and fragile: http://www.store.yahoo.com/drillcity/10pacwirsizd.html I checked here and found Cobalt Micro Drills. For a .004" drill bit, it's $7.40 each, but you must buy 10 at a time, and they are metric, so a .2mm = .0078" for $4.55 each, so 10 costs $45 bones: http://www.cetdirect.com/pub/Products.asp?catID=5073&pID=0 I'm guessing you want to get a few guys to go in on the deal with you. -Robert
You can go to a Dental supply company and ask for #1/2 round burs. That bur is much smaller than a #80 bit. Stay cool and run steam.......
