Page 25-06 Can I substitute a .380 reamer for a .375?

[bertschb]

The plans on page 25-06 call for reaming some holes in the fuselage bulkheads to .375. My Cleaveland Tools kit came with a .380 reamer, not a .375. Is it OK to use the .380 reamer here??

Cleaveland labels their 0.375" straight flute reamer RSF380 (i.e. 3/8"), so it might actually be 0.375". https://www.cleavelandtool.com/prod...1&_sid=192e0ef01&_ss=r&variant=31450373193790

NO!! use the proper reamer. $15 or so for a quality high speed steel reamer from MSC.com

Never take a short-cut. Find something else to work on until you acquire the correct sized reamer.

Thanks for the reply.

I just checked and the package is labeled .380. But, the reamer itself is labeled 3/8 which is .375 so I'm OK. No clue why Cleaveland labeled the tool .380. Probably just to throw off this rookie builder.

Believe me, I don't take shortcuts! I've spent over $10,000 on tools so far. It's also why I asked the question even though the difference is only .005.

The RSF380 reamer received in my Cleaveland kit is labeled "3/8" on the shank, and measures 0.375" (3/8") with my digital caliper.
