Accusize Industrial Tools Style Axa Turning and Facing Quick Change Tool Post Holder for1/2'' Turning Tools, Style 1, 0250-0101

I have been using Accusize products for several years and have had no issues what so ever.I recommend Accusize to my friends

First off, it fits my LLDSIMEX tool post perfectly. The four star is that the bottom of the tool channel has a slight radius on the inside corner so the tool body cannot go flush with the back of the slot. This has been standard for years across the OXA market. A similar part purchased a few days later had a slight undercut allowing a flush mount, a significant improvement. One problem with China sourcing is that it is impossible to identify the supply channel factory. For instance from the factory or machine that made the LLDSIMEX parts and a couple of no-name parts from last year are 0.790 +/- 0.002 wide and 1.1015 +/- 0.0005 high. Hard to believe that's two different factories. The Accusize part and the undercut part are 0.788x1.106+/-0.002 so I suspect the same source. If so, the Accusize parts may show up with the desirable undercut. Be careful as there is another source ( 0.755 wide and 1.087 high) that is selling cheaper pairs. They have a 45 degree saw-cut into the channel bottom which appears to substantially weaken the part but more importantly the dovetail is cut too deep and they don't work with my tool post.

Great as always

Nice fit and finish

It's OK. It's the same basic part as the 201/202 holders, except this one will take 3/4" shank tools. rather than the max 5/8" shank max for the 250-201/202. I was hoping they'd made this XL from a piece of steel that was 1/8" taller, but all they did was mill out an extra 1/8" from the top and back of the slot for the tool bit, so you've got 1/8" less threads for the setscrews and 1/8" thinner steel web behind the dovetail . Other than that, it's exactly the same as the 250-201, except a bit weaker from cutting away more metal, and it will take 3/4" x 5/8" shank as a result of cutting the slot taller and deeper. So, anyone with a mill could convert their 250-201/202 to XL just by milling 1/8" off the top and back of the slot.It would have been a much better tool if they'd made the whole thing at least 1/8" taller and thicker.They are well made, and the price on them is the best I've found. They fit well. They are great for mounting and configuring a tool for a quick change. I highly recommend these. The only negative about them (and it's the same for all brands of these), is the rather marginal setscrews that are supplied with them. For starters, they are way longer than needed, Next, they have a weird end that the last 1/4" or so is not threaded. It doesn't matter much if you are using 1/2" tools in the holder (or 5/8" for this XL), but for 3/4", it means the setscrew is so far out only half the threads (of this probably marginal steel in the first place) are engaged, thus increasing the chances of stripping the screw or holder threads if tightened too much. I have about 20 of the 250-201/202 holders, and I've replaced the setscrews on most all of them, especially when I'm using 5/8" shank tools (or 3/4 or this one). I've never had any problem with any of them. Also, on all of them, the threaded screw that holds the height adjusting nut is usually installed rather loose. The best thing to do is remove it, clean it, then reinstall it tightly.

Someone here mentioned slight step in the pocket. The tool mates on the angle portion of the dovetail (back edge) and the tool post plunger pushes out on the center of the flat. So that slight step means nothing. Look at the other holders in you tool post set....same thing. Also the slight radius in the lower corner of tool cutout will add strength to holder. Just belt sand a slight chamfer on the corresponding edge of the tool you are using. Now it sits flat!

I gave this four stars because of the price, but the holders I purchased were manufactured with a dull mill that left a radius in the bottom/rear channel for holding the tool. This prevents tools from properly registering against both the bottom and rear of the holder channel. You can either re-mill it yourself or use a triangular file to remove the radius. But expect secondary operations for a good tool fit.

Bought as a gift. Recipient pleased.

The media could not be loaded.  Well I know this was going to be a bit loose on my Armstrong tool holder (Made in USA, Chicago) but did not expect this to be worse then the one made by (well imported by) Shars... but it was. It goes all over the place. Look how well does US made tool holder fit on attached video. Even Shars is not that bad. I guess if you want some quality you need to roll your own or get used ones from eBay. New US stuff is expensive but top notch.Now I know that for unknown reasons when the Chinese copied Aloris design they made their copy a bit bigger - probably changing from imperial to metric and rounding up but I did not expect that Accusize will be even more off then Shars.

Great finish to these products, very well made. They allow the use of 5/8 inch shank tools which is a great help when using carbide tips. I've never been able to find a 1/2 inch tool to take a carbide thread cutting tip, which is all the normal AXA toll holders will fit, so very useful, well worth the money.

Inside has poor machining/grinding. 0.034” high on the inside dovetail.Block on the right of the second picture. Larger block but smaller, looser, set screws as well.

Tool Holders fit the Tool Post on my King 12x36ML Lathe3/4" Tools will fit in these Tool Golders, however, the unthreaded portion of the Clamping Screws must be removed (not an issue)

Works well on same brand tool post.
