HHIP 2000-7035 1/8 x 11/16 x 5 Inch 5% Cobalt P3 Parallel Type Cut-Off Blade

if you have anything heavier than a 7x16/8x14, then it'll work, but it will absolutely not cut anything with a small machine. i'm trying to part aluminium and copper but no matter the feed, speed, sharpness, upside down cutting, and normal cutting, it will not part anything. EDIT: came back after modifying the cutting edge geometry and it cuts everything, even steel on my mini lathe. it seems the cutting edge out the box is very very dull and puts a lot of strain on the spindle. i've modified my cutting edge to be aggressive and razor sharp, cuts like a champ.

As advertised

This does work well enough but I can't say it was the smoothest parting tool ever. I do prefer this hss blade style parting setup. Stays sharp a while longer than some others with good cobalt % for the average hobbyists or smaller machines.

I bought one of these a while back and it has been performing very well. It did need a little touch up on the cutting edge, but that is to be expected since people use different set ups. I use this in a BXA 250-207 holder so the angle it pretty close to what I need. When set up right this blade cuts through steel like butter. I have used it on Aluminum, Mild Steel, 12L14, and a couple types of Stainless. I am buying a new one because I made a mistake while parting. I was using tail support on a part with a large hang out (planning on removing when I got close to finished) and screwed up when I went to remove the tail support resulting in a broken blade. I was able to fix the blade (which is shorter now) by grinding it again but I wanted to have the full length.

I am new to machining and this is my first use of a parting tool. I was warned to wait until I "got my feet wet" before attempting parting. Plus, I was told to "stay away from the cheap tools until you break a few high dollar ones". Well, I got my feet wet, but jumped into the lower cost unit right off. I am VERY HAPPY with the decision. Like anything else, setup is the key to parting. BUT...if you set up correctly, and watch your feed/speed, this tool is AWESOME! Immediately, it looked like I knew what I was doing. No chatter, and the tool did not try to walk up or down the material. I should shay that I use a Precision Matthews, 1440BV lathe, which I also love. Definitely worth the money!

I had to re-sharpen the cutter, The angle was off just enough so that it would not cut center line, works great now on aluminum bar stock, HHIP 2000-7035 1/8 x 11/16 x 5 Inch 8% Cobalt P3 Parallel Type Cut-Off Blade, I have not had a chance to try on Steel as of yet, When I do I will come back and edit review. 02-18-2021 > OK been using for over a year now, Has proven to work great on any thing I have had to part, I have made several brass bushings and steel spacers, I use plenty of lube and have not had to re-sharpen so far well worth the price.

Cut ok after re sharpening, factory grinds were very rough but I assumed it would need to be touched up

The narrow profile of this parting tool greatly reduces the amount of power needed to cut through material at a reasonable rate. This is particularly important with mini lathes (8" x 16" for example) that have a limited amount of available torque Of course it cuts through aluminum with ease, as can be seen in the photo. But it also carves its way through 304 stainless without much strain, leaving nice "clock springs" of metal coming off the work piece. And it's maintained its edge well, even when machining steel.

Does what it is meant to do, I had no problem parting off on 2" aluminum bar stock. Have not tried it on ferrous metals yet, but I also have an expensive Pramet parting tool with carbide inserts that I could not to get to work as good as this one. And could only do up to 1-3/4" at most. I have not used the 5/32" or the 1/8" but they should work just as well.

Parting tool for my lathe

Sharpened it and proceeded to plunge it 1.5" into 304SS. Five stars

Being of small demention I have to hold it to work as close as possible and cuts very well. I'm just a hobby guy and very satisfied with it.
