Spent a few hours watching videos and reading about these Diamond Tool Holders and am very close to ordering one.
Am I falling for the marketing or are these as good as what they are talked up to be?

I like mine. I haven't use it a lot but it's worked good so far.

I have one I bought from Rudy Kouhoupt ar a show in Oregon. It is my "go to tool" on my SB9. For bushings with shoulders and similiar parts it is real handy. It is mounted in a quick change block that I built that sets the desired 12 degree angle. The quick change block is a great improvement over the lantern toolpost.

I have had one for years also have a few homemade tangential variants, they are good cut very well and single facet sharpening is a real boon, there are quite a few home made designs on the interweb so if you want to save a few bucks....

I have had one for years and would not sell it. I like it but is it the best thing in the world...no.
I still go to my ground HSS blanks and insert tools (carbide and HSS) depending upon what I am cutting.
Don't get me wrong, it is a good tool but not the best thing since sliced bread.
I would rather get another 7-10 quick change tool holders than one tool.
This all depends on what you have in the shop right now.

They can really hog off DOC too, even on SB 9" etc. I find the best thing about them is quickness of re- sharpening. Literally off the holder, into the jig, 2 seconds on the bench grinder, back in the holder and away again. Complete time taken, less than a minute. I also have plenty of butt welded HSS form tools, home made solid shank HSS grinds, and the odd carbide and insert tipped tooling. It does get used a lot.

I use mine for turning plastic, especially soft stuff like urethane. I can easily sharpen the tool to an incredibly sharp delicate pointy-spindly shape that shears like crazy with its tangential attack

I find its a versatile tool and use a bit of 1/4" round HSS sharpened in the jig....nice cut on plastics and metal

Make your own and see if it would have been worth the price. :-) Use the saved cash for something
that can't be made so easy.

Yea, I agree. It's a good project. Built my first one about 45 years ago. At that time, Alcoa had a patent on them and used them in the quality control labs. Since I was an apprentice machinist, My boss had me build a couple for our labs. Good project. Good luck.

Hey Jim. Thanks for the info. Looks like a nice tool to have. Kinda pricey but they look like they are quality and there was some planning that needs to be paid for.

I agree with the others, it would be a great project. Dont forget HSM magazine had an article for one also as well as projects in metal I think.

Hard to do though without a mill or shaper :) I kinda wish you didnt post it though. Know why??? I want to buy a set!!! Dont wanna make one. Not right now.

Let us know if you buy a set and how you like them K? JR

I have read a good bit about it over time but have not - am still not - convinced that I need (or want) one as I've got by very well with the common run of the mill stuff for a long time.

Hi guys,
I have a Sieg Mini Mill, but I admit....I honestly don'tthink I possess the skills to fabricate one of these, so I would have topurchase one.

I got one with the tooling that came with one of my lathes. It's interesting, and has it's uses, but it's no magic bullet. I guess I don't do enough "normal" turning to bother- the typical diamond tool can't do right-hand cuts or shoulders well, or groove, and you have to regrind the tip for threading, it can only do the shallowest of face counterbores, etc.

I mean, nothing wrong with it, I'm sure it works well for many users. I personally just don't see any real benefit over normal HSS other than it's supposedly "easier to grind". (Which is horsepucky, but I won't get into that. :)
