7/8” reamer- What Now?

[KBeitz]

Look for a larger tail stock chuck...

 

[kd4gij]

A) buy a 3/4" chuck,
B) Buy a 3mt er40 collet chuck,
C) buy an 3mt 3/4" end mill holder,
D) All of the above.

Put it in a boring bar holder on your QCTP.

Great idea. I think I can do this! Have to go check my boring bar holder to see what size it is.

Thanks,
Glenn

Make a split sleeve for your boring bar holder if neccesary or use a #2 tool holder and tram it in true .

If you have a surface grinder and a spin indexer I would fixture the shank in a 5C collet then grind the last inch or so to a size that will fit your chuck. I've done this successfully to both reamers and end mills. I've also relieved the shank on several end mills for clearance when plunging deep holes.

Shaft should be soft enough to turn down to 1/2 - 5/8” that’s what I did with my large reamers so I can use them in whatever .
