Lathe Grooving Tool Holder Grooving Cut-Off Tool Holder MGEHR1616-3 With 11pcs MGMN300-M Indexable Carbide Grooving Inserts

Excellent grooving tool, slightly different than the model pictured as it has a curved lower edge that slopes down towards the front, this is a REALLY good feature as adds additional support to cutting edge. Limited maximum depth of cut off, around 25mm ( 1" ) but that's to be expected. The supplied cutting insert were also worked perfectly well, not sure about how long they'll last but again at this price that'll be a lot of grooves cut. Definitely worth the money.

A very good cutoff /grooving and profiling tool ,good for everything except roughing . only downside is the insert doesn't last as long as bigger insert tools, but for getting in to tight spaces is where it shines. Cut a lot of stainless with this cutter.For the money its impressive and the inserts are cheap to.

Using these as a parting tool, was pretty pleased with the function, used on aluminum and Stainless Steel. Like usual on stainless you need to keep the rpm down and increase feed speed. This worked where other parting tools I've used were less than useless, a couple others bought them after I told them I got pretty good results. They have also been pleased with there function. Maximum depth is not spectacular, but adequate for what I needed, I will be reviewing this tool to see if there are others with another inch in depth reach.

The tool itself it great. I have been employed as a machinist for 38 years and the tool is excellent and given the price, a real bargain. The carbide inserts on the other hand, not so great. The first job I used the tool on was for parting off some Type 316 stainless steel and I soon figured out that I was able to cut off one part per insert cutting edge. Type 316 is tough stuff to work with so I suspect that most other materials would give a longer cutting edge life.

They worked perfectly and a good deal

I purchase this tool for a 10 inch lathe that normally uses 1/2 inch shank tools. My tool holder is large enough to accomodate this larger tool. However, there is not enough adjustment to lower the tool to the center. I like the deeper bottom holder for the carbide tips since this is what usually breaks. That made it worthwhile to cut about a quarter inch off the bottom to allow centering. I read the negative reviews on the inserts. This was a concern since all my insert are from inexpensive sources. Purchased expensive Korloy inserts to test against the insert that came with the tool. The inner groove was made with the Korloy insert and the outer groove with the inserts that came with the tool. The metal is 1 inch diameter 304 stainless steel. To took me half the time to make the outer grove than the inner. Don't see an advantage in spending more money on a name brand insert.

Why pay more? These work great on my 12" - 2hp lathe. I pushed my last one a little too hard, the insert snapped and took the tip of the tool with it, so now there's no support under the tip of the insert. It's also cheaper to buy this took with the inserts included, than to buy the inserts on their own!

Gave up after 2 bits broke on 316, barely scratched it.

Está bien construido, los insertos ajustan bastante bien. Hace su trabajo. Creo que por el precio está bastante bien

Geht so...für kleine Sachen. Material ist zu weich und biegt sich unterhalb der schneide
