need a source for a 51 mm reamer , prefer #3 morse taper shank

I prefer working in metric, but sometimes metric tools are more difficult to
find (at least, here in the US) and are usually more expensive than English
units tooling.

With that in mind, 51mm = 2.008". So unless that 0.008" (0.2mm) makes a
difference, I'd try a 2" reamer.

Regards,
Michael

Mapal makes reamers up to 300mm or so as standards.

They have loads of distributors worldwide.

Seems like a long way to go with a hone...?

They are available, but probably in MT4, not MT3. The job is to open up a
2.005 hole to 2.008. The method is determined by the volume. You can buy or
make the appropriate reamer, but the cost will be around $200 plus time. If
this is a short job, I would consider honing first or boring second.

..003" isn't much for a 2+ inch reamer to take off. Honing or I.D. grinding
would be a safer bet. Especially if it's a one part that has to be right
kind of a deal.

this is to ream a sleeve that is 1045 material and 12 inches long , the
sleeve is put in with liquid nitrogen for a .003-.005 interference fit

because the od of every sleeve is different , ranging from 2.780 thru 3.955,
I want to be able to quickly and reliably size the bore in the field , I
did mention this is being done in the field didn't I

approximately 60-80 sleeves

I am having the sleeves gundrilled oversize by .002 so the reamer should
have a very easy life


got a couple of quotes today @ 185.00 each if I order three , which is not
too bad

have to have the MT 3 as that is what fits in the mag drill

I agree.

But, didn't he say he had like 80 of these to do, in the field? That's
a LONG way to go with a hone.

Check out Adjustable Chucking Reamers. For a example see page 90 of the
online KBC Tools catalog. http://www.kbctools.com/usa/main.cfm A 2" is
adjustable up to .055" and is listed at $330 for UK brand and $389 for
US brand. I am sure any of the major suppliers will have something
similar. It doesn't state what the taper is on that particlular size
though. We are using these at present for a long run job on a cnc, but
with carbide blades

Not really. Depends on the stone you use and the finish you want.

Perhaps a "pull reamer" with a pilot....go a couple thou under, then roller
burnish..otherwise his surface roughness alone will make certification to
+/- .0002 next to impossible.

The whole deal appears to me as a leisurely drive down the road to
failure....but at least he's taking the scenic route....
