Thread mill recommendation

[Eric U]

I'd like to move a threading operation from my lathe to the mill. I need to thread mill a 1-1/8x20tpi thread 7/8" deep in aluminum. There are what seems like a million thread mills out there. Inserted ones, solid carbide, etc? Brands? Coatings?

Thanks,
Eric U

I use lakeshore carbide for 4 flute solid carbide thread mills, they have decent pricing and perform pretty well. Don't have any experience with inserted Threadmills but they do get pricy and due to the shank size are generally limited to OD work only.

i don't recall if they have any uncoated cutters but the coated still work well in 6061. I have several of their 20 TPI mills and IIRC they have close to 1" LOC.

They do now. The 1/2"-20 TPI tools have exactly 7/8" LOC which should work fine for the OP.

I have great results from the Lake Shore Carbide product

Now remember I had to put a larger chamfer on to get a full 1" of threads.

Vargus is a one stop shop for me...

They are experts in this field, have some great products and pricing is reasonable.

Good technical support here in the UK also. I'm sure you'd find the same in the US.

We've been using Advent Tool & Manufacturing, Inc. www.advent-threadmill.com with very good results. They are great when calling for information. Used Vargus in the past they are good too.

I've got some Lakeshore thread mills I use for other applications. I'd prefer something with at least a little extra DOC so I'm not right on the edge when it comes to chamfers and such. I looked at the Advent website and they have some nice looking stuff, but at nearly twice the price of the Lakeshore ones. I'll get something by the end of the week.

Thanks for all the input,
Eric U

Try Advent's single flute indexable threadmills if you're not doing large quantities. The bodies aren't expensive and you can buy inserts individually at around $35 a piece. You lose productivity over 4-flute solid carbides, but they're still better than single tooth cutters.

Lakeshore can probably grind the shank back for extra depth. I know AB Tools can, another mfg'r to consider. No idea what they charge.

Wow! Glad I read this thread. I just ordered two thread mills from Lakeside for 2/3's of the cost of One from MSC. Great Pricing!

Maple tools has them in stock right now for a decent price

Would somebody please ban Brianless Brant who is doing nothing but bumping old threads and shilling for his company?

A company that now will probably never see a penny of revenue from any PM member, since we all HATE spammers?

Way to go, Brant, you've permanently damaged the reputation of Maple Tools. Hope they're paying you well to trash their online reputation.

I've been getting threadmills from Redline. They work as well as the Harvey's I'm used to, but cost less:

Sorry it looks like that, I was just giving an option, answered the question asked

Replying to a thread that is 9 YEARS OLD is typical spammer behavior.

New marketing guy, trying to be a "go-getter" when he SHOULD be focusing on their terribly not user friendly website.

Technically you're not wrong, but when all of your posts are just links to a website, that makes you a spammer.
Go away.
