I did a group buy for dies a few years ago, and it went very well with people sending money and participating.

I am now needing to buy a few more dies and I am looking for a "Good set" of taps...

If I remember right, and will confirm soon, taps must be purchased in sets of 5 for each size from OSG. SO there would have to be some harmony and agreement on the taps unless you wanted to purchase a set.

Here is OSG's website http://www.osgtool.com/index.asp ...its easy to navigate the catalog... I am thinking of buying the Hypro series of taps and a good all around set (I have more reading to do)...

If you have interest, please PM me with a basic idea of what your looking for. These prices will be lower than list if all works out the same as last time.

Thanks

Rob

EDIT: OSG will sell by the individual tap. The taps I am looking at are "List 280"

Why on earth would you spend that kind of money for dies? "Special Alloy Tool Steel", why not HSS? I can't imagine them being useful for anything but cleaning threads.

Is that the price of "each" (i.e. one die), or the set of five price that you mentioned

Having used mine for a couple of years both at home and work has shown them better than anything i have used...maybe one of the other guys who bought last time can say something about them...

The price of each die...ie 35.00ea for the smaller ones

Just a quick look and I found http://www.westtool.com/default.aspx?page=item+detail&itemcode=OSG+2706100 which has the first die you listed for $35.11. The bigger ones are a bit more than your shown prices.

Just a FYI. You are way out of my tool budget range. :)

"Why on earth would you spend that kind of money for dies? "Special Alloy Tool Steel", why not HSS? I can't imagine them being useful for anything but cleaning threads."

What I meant was, that's a lot of money to spend for marginal tools. By marginal I mean tools that don't do a very good job of threading.

And you'll be hard pressed to do the larger sizes by hand. Ever tried turning a 1"-8 die by hand? There's the problem of starting the die straight onto the blank too.

With relatively thin dies it's almost impossible to maintain correct thread pitch, you have too few threads behind the cutting edge to provide pitch guidance. When the few guide threads can't keep the pitch correct you get what's called "shaved" threads where the guide threads in the die are cutting the flanks of the thread thinning them. You notice this when the cut thread seems unusually loose to the nut.

Years ago I picked up a good customer because they were using these type dies to thread rods. They couldn't figure out why nuts wouldn't screw on consistently down the threaded area. Looking at the threads with an optical comparator showed the pitch varied slightly at places. Very common problem with thin dies.

I don't have a less expensive solution to threading. Equipment to do good threads is expensive. I just think this is money not well spent.

... must not know anything about OSG ... :)

You'll be hard pressed to find a tap or die better than OSG, especially these days when more and more of the old brands are outsourcing to the far East. OSG's "special alloy tool steel" is a HSS, it even says so in their product literature. You realize that saying "made from HSS" or "special alloy tool steel" is all marketing BS. Without providing any details of the alloy, we take the manufacturer's word that it's a quality product.

As far as the usefulness of dies ... if it's a standard thread size and I have the die for it, I use a die. It's way faster than single point threading... Even if you don't make your own die head for the tailstock, you can still use the lathe. Use the the flat face of the tailstock and gentle pressure to start the die properly. Gently rest the die stock handle on the saddle. Engage lathe at low rpm with plenty of oil. Shut off lathe. Reverse. Viola - perfect threads in no more time than it takes to sneeze! If it's a large thread, then I cut one pass with a single point tool. Still quicker than doing the entire thread via single point.

By the way, I have cut new 1" - 8 threads on 4140 shafts using a 3" die stock and an old Greenfield die. It was not particularly difficult (maybe you don't know how big a 3" die stock is).

Yes, I know very well OSG taps, that's all I used for many years in production tapping stainless, OSG EXO-taps at a high price (3/8-16, I believe is over $30 now), but worth it. This thread refers to dies though.

As to OSG dies, they may well be as good or better than any, I still don't like dies of this type and being in the machine shop business would not give 50 bucks for the assortment, much less cue's price. No matter how you feel, a die of this type will not cut good threads time after time. They are nice to clean damaged or rusty threads.

BTW, if you're in business you better hope the OSHA man doesn't see you threading the way you described in the lathe.

Rob, Thanks for the offer but I'll have to pass & make the old Gtrrnfields work for now. What I have is mis-matched but will have to do. Again thanks for the offer!
