Greetings! I need some opinions and a little direction. I'm in the market for a parting/grooving tool holder and I would like to know what works for you. I'm looking for a BXA size for an Aloris QCTP. Lathe is a PM 14x40. Thanks in advance!

Just type "parting tool" in the search box up in the upper right corner. You will find a veritable plethora of articles on parting tools.

Been there done that Chuck. Didn't find what I need. I'll do a better job of asking my questions.

1. Is an Aloris parting tool holder worth the extra $100 bucks? Any comment on other brand holders? I have the chicom knockoff that came with the lathe.

2. Are insert tools worth it and do they work well? I've been using a T or P style tool.

Maybe this helps.

No., for a hobbyist Aloris is an extravagance.

As to inserted cut off tools, If you cannot sharpen a cut off blade, the inserted tools are OK, If you're into production, Running High RPMs, inserted tools are OK. If you're a hobbyist, and time has no value, (your're not making a living cutting off washers) then the money for an inserted tool (and the inserts) can be spent in better ways.

Are you looking for a different tool holder because the one that came with the lathe isn't working for you, or are you just trying to figure
out if there's something better out there?

Thanks for the reply Tom. I agree with both of your statements. I lucked into a Aloris Tool post, made a trade here, I have 1 Aloris tool holder and it works just like the others.

Great question. I'm just trying to improve my process. What I have now isn't working for me. Chatter, the blade doesn't want to stay tight in the holder, wants to turn out. Blade too small? And yes, if there's something out there that's better I want to know about it. Thanks for the reply!

So, it sounds like what you have is a wedge type holder like the pic? With a T blade, when you tighten the screw they tilt in the holder due to being
thicker at the top. This presents the blade to the work at an angle which can cause problems. A shim between the blade and the holder
at the bottom will help: I measured mine and use a narrow feeler gauge which squared up the blade to the work. All the usual advice applies: use
a decent quality blade that's sharp at the correct speed, make sure the blade is exactly 90 degrees to the work and at the correct height, use lots
of lube. Make sure the blade doesn't extend out of the toolholder more than needed and that your setup is rigid. You should be able to get decent results with one of these holders if your setup is correct. If you're getting chatter, try slowing
down the spindle RPM.

Thanks NoGoingBack. The shim was what I was looking for. I thought about that, but didn't know if it would work. I'll give it a try.

I have both Aloris and chicom holders, the Aloris is worth the extra cost. Also, some of the cutoff blade holders have centering grooves that hold the blade without tilting. My Phase II holder doesn't.

Couldn't you just machine a small slot along the top of the cutoff blade holding surface on the tool holder (that way you would not have to use a shim to keep the "T" type blade flat)?

I just checked my Phase II holder and surprised to find the t-blade is sitting there at a cattywompus angle, nob much of an angle but an angle never the less. I see that the back side of the blade is worn from contact with the parts IOve been cutting off. Hasn't seemed to be a big problem, but...
I'll have to try the spacing shim and see if that helps out. Thanks.

The real issue, at least on my Phase II BXA holder, seems to be that the bottom of the blade is unsupported on both sides and moves, leaving the blade not vertical. A shallow slot at the bottom of the blade recess might be better, and shimming the bottom on the inside might help best without modifying the holder. There is not enough room to mill a slot at the top clamp, my T shaped blade fills the available width.
