Accusize Industrial Tools Style Oxa Turinng and Facing Quick Change Tool Post Holder, 0250-0001

So far, I've been happy with Accusize products, and this tool holder is no exception. It's nicely machined and finished and fits my tool post perfectly. All for a decent price.

I wanted to see if I could mount 3/4 inch tools in my AXA holder. The answer was; not right out of the box. But an added shim to the stationary side of the dovetail on the AXA holder and it locks in tightly. So far not a problem.

I think this is every bit as good as the original mounts that came with my lathe. Likely even better.Very happy with the purchase- I got it just to have an extra around for semi-precision cutting to save time. I was so surprised to find it works completely as good as the OEM at a fraction of the cost. I am buying a few more to keep many of my cutters ready.

to an already great set, but when you need another for an additional cutter.

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.

To save changing tools all the time it's so much easier to have extra tool holders. Rather than changing out tools I simply get another quick change post. It's one of those things where you can't have too many.

I like having a lot of these.

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.

Works well on same brand tool post.

pour machiniste amateur comme moi et je suis tres satisfait

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)

its good
