I use to buy reground end mills from wttool but they no longer sell them. I searched online and once you say "re ground" every company's name pops up because they offer this service. I want to purchase reground end mills not have them sharpened.
So who sells them today?

Might check with a local tool sharpener.

I've had lots of tools re-ground but I can't say I ever saw a place selling re-ground stuff. If you want to go that route I'd look for batches of used tooling online and have it re-ground--it'll probably be about the same price...

I have in past years purchased a number of resharpened end mills on Ebay, lots of options there.

http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.A0.H0.Xreshar pened+end+mills.TRS2&_nkw=resharpened+end+mills&_sacat=0

I believe the ones I purchased were from mmtoolscarbide. No issues with their products or service.

Random link to one of their Ebay items (http://www.ebay.com/itm/3-RESHARPENED-5-8-ROUGHING-HSCO-M42-ENDMILLS-4-FLUTE-5-8-SHANK-J483-/332023805173?hash=item4d4e2934f5) just for reference.

I bought a few ~1/2" carbide regrinds that work well: http://www.ebay.com/itm/CGS-END-MILL-1pc-485-4FL-SQ-END-REFURBISHED-CARBIDE-END-MILL-LOT-485-4FL-/262681915362?hash=item3d290fefe2:g:MkAAAOSw-W5U08c0

There was a guy selling one on Ebay, but it looked like it was stuffed into the back of a drill chuck...

There are lots of resharpened end mills on e-bay. On the Practical Machinist forum I often see regrinds for sale.

Might as well buy new as pay the incredible shipping that the vultures on Ebay charge.

Often times if interested in an item I will contact the seller and ask for an item to be shipped USPS, small or medium flat rate box, much cheaper.
Most merchants have no issue with this option, if they do, move along.

Hi,

The few carbide resharps I've bought have come from eBay. Been pretty happy with them too. I look for lots, they tend to work out cheaper per piece.

I have bought reground and recoated carbide endmills on ebay, they are much cheaper as long as you don't mind the slight reduction in length and diameter.

The loss of dia can work to your advantage in many cases. If you have a selection of regrinds, slots are easier in many cases. Bob.

Use caution, some reground end mills are sold because after grinding it was determined the diameter was reduced enough to eliminate the "hook" in the flute. In other words they aren't free cutting enough anymore even though they have been sharpened. Sort of like the difference between positive rake and negative rake tooling, with the regrinds tending toward negative.

Somewhere I have a chart from an aerospace company showing the acceptable diameter reduction allowed before the end mill is considered unusable and should either be disposed of (sold as a regrind) or have a relatively expensive refluting. Generally, refluting is not cost effective on HSS end mills unless they're larger sizes. Carbide can be more cost effective to reflute.

If you find a steady source of regrinds you might want to check why they're selling them. I'm betting the odds are the cutters are rejects. But, a cutter rejected for production might still be home shop acceptable.

The rule of thumb is that once it reaches 10% smaller than original, it's done. For example, a .500 (1/2") would not be any good below .450.

The Kennametal 10mm carbides were 9.5mm and recoated by Kennametal, I am more than happy with them. They might be more trouble if used in a CNC machine.

All good points posted here. But what I was looking for is a company that sells reground ones and has a list on their website. That way it's easier to select dua, flute length, overall length, flute qty, etc. I have also found that companies that sell them only bother with the good name brand ones and they sold for the price of an equalivant Chinese new one....

Hi,

Resharps are like gold for CNC machines. I find them far more useful than new ones because its much easier to control tool size.

Here's an outfit that does large quantity resharpening, or at least they used to. They may have used re-sharpened for sale, I don't know.

US Tool Grinding Inc
2000 Progress Drive
Farmington, MO 63640
Phone: (573) 431-7945

To get a reasonable price you had to send them a couple dozen of exactly the same end mill. That way they would setup an automatic grinder and process the whole batch in one setting.

They were the only place I could find to correctly sharpen our 3/8" spiral flute taps. Some I would send them were broken off right at the tip. They would find the shortest of my batch, cut all the others to that length and sharpen. We would end up with shortened taps which were fine for our use. Back in the day those taps were around $20 each, maybe $6 to resharpen in batch lots.

Interesting... But, very few end mills.

I called Steve to ask about something else listed on his site. Apparently, what you see listed is all that will ever be available. He's not buying any more inventory.
