Got paid today...tool gloat!

Nice!! The noise level at Crosby Machine Company is about to drop considerably!

Got the R8-to-1" shell mill adapter in the mail today. I must say, very good quality in it's appearance!

Country of origin: Taiwan.

Not unhappy, it's better than the Chinese one I have.



I'll try to get over to the shop sometime this week to mount the cutter on it and give it a whirl (literally) in some 1018 steel.

It definitely looks better than the typical made in China version. The other one I was going to post a link to was the Glacern. They're also an import but the pictures sure look good. They look almost the same as the GS Tooling.

I went over to the shop for a short time and checked the runout of the new holder, then mounted the cutter on it. Too late to be taking cuts but I'll try to get to that later, perhaps tomorrow afternoon.

The runout on the 1" pilot diameter was measured with my Interapid 312-B4 (tenths) dial test indicator was about .0002" (0.005mm), very good I think. For kicks I checked the 1-1/4" Chinese made one I have that has no cutter, it measured .0008" (0.020mm), which is barely acceptable in my opinion. After mounting the cutter, I checked from insert to insert and got a T.I.R. (total indicator reading) of .0004" (0.01mm), which is still excellent given you could expect a little variation in a class of ground inserts "G", which is +/-0.001" (0.25mm).

Here's a shot of the cutter mounted, ready to go:


And one of my small array of face and (one) shoulder mill with "shell mill" mounts.


All Walter cutters now, from left to right:

3" 6-insert F4080.UB26.076.Z06.04, 43º lead angle, 4mm (.157") max depth of cut, 2.206" effective cut diameter. Inserts for steels, cast iron and aluminum in stock. Eight edges per insert.
2-1/2" 4 insert F4041.UB.064.Z04.13, 90º lead angle, 13mm (.512") max depth of cut, 2.500" effective cut diameter. Inserts for steel only at this time. Four edges per insert.
2-1/2" 4 insert F2280.UB.064.Z04.04, 43º lead angle, 4mm (.157") max depth of cut, 2.106" effective cut diameter. Inserts for steels., cast iron and aluminum, same ones as F4080.
2" 6 insert F4033.UB.051.Z06.06, 45º lead angle, 6mm (.236") max depth of cut, 2.000" effective cut diameter. Inserts for steels and stainless steels. Eight edges per insert.

I could never get all, or even 50% of what any of these cutters is capable of doing with only 2HP, but they're still really nice to use and my investment is still under $200 for all the holders. I probably got another $200 into the inserts, and will want more to be sure each can handle steel, cast iron, austenitic stainless steel, superalloys and non-ferrous as various jobs hit the floor.
