Great miter box for picture frame stock
This aluminum miter box is great for rough 45 and 90 degree cuts. No matter what miter box you have there will always be inaccuracies when cut. This is more so from saw movement than improper angle placement. These inaccuracies are easily cleaned up with a shooting board or simply ignored if + or - .5 degrees is acceptable for your project. My project is picture frames. So, four miter joints can add up to a lot of error and gaps are much more noticeable in picture frames compared to say, baseboard molding in a bedroom. The miter box I received has two 45 degree cutting slots. One is quite accurate and I can rely on to produce a proper 45 degree angle + or - .5 degrees or so. Two or 3 passes on my shooting board plane and I am good to go. The other 45 degree slot is much less accurate. Im guessing it may even be off a degree or two. Again though, I can use it I just need to spend more time finishing it on my shooting board. The 90 degree slot works very accurately and is also easily cleaned up on a shooting board. The miter box opening to put material in to cut is just under 3 inches wide (~1/32nd inch shy on mine) and 2 1/4 inches tall. It is around 9 3/4 inches long. The width of the cutting slots is pretty small, but it does fit a standard miter box saw. It also fits most any razor saw. This miter box has a clamp part that can be screwed down into the work being cut. The clamp end that will touch the work is around 1/2"x5/8". It is kind of small so I usually put a small piece of 1/4" softwood between the clamp and the work to prevent damaging the work. Another thing absolutely essential to using this miter box effectively is to put scrap wood on the bottom of the box. This prevents you from hitting the aluminum when you saw through the work. I have attached a picture showing my setup. I have also attached a picture that shows the capabilities of the accurate 45 degree slot I have. Pros: *One of the 45 degree slots and the 90 degree slots works well *Small cutting slots that provide an accurate cut *Built in clamp that is very useful Cons: *One of the 45 degree cutting slots is very inaccurate(-1/2 star) Additional Considerations: This box does NOT come with a saw. You will need to get one. I recommend a <link jap saw> Overall: 4.5/5 stars (>=.5 rounds up, <.5 rounds down) => 5 stars If you have any further questions regarding the product in my review please leave a comment below and I will get back to you as soon as possible.

Been looking for a good M-Box for years!
This thing works great for small work like baseboards and trim. Get one of the long Japanese saws that are thin. Just squeeze the top sides in a bit to get the clamp to move. Put the box on its end to load the clamp bracket so you can see how the groves mesh. I use a thin piece of wood under the trim and a piece of heavy foam board above it so the clamp does not leave a mark in the trim piece. Level the trim and square it to the box. Clamp the three pieces down and slowly cut joints that match so good they don't need caulk. Mount it in a way that the trim pieces will be level to the box for their complete length and will not put any undue torque on the box or clamps. This saw from here works great. (Shark Saw 10-2210 Miter Box Saw) Careful, very sharp and a slight touch will be painful!

OK. Works well>
Made of aluminum works well for balsa and other very soft woods . Wears quickly due to teeth of saws. no way to prevent this. Heavy use a life of about 6 months, moderate use about 1 year, (BALSA ONLY) My overall opinion is this is a good product as designed. It fills a need. it is inexpensive and accurate.I will buy this again.

" Old School Quality" mitre box delivered!
I love this mitre box! It's all metal, rugged, and exactly the quality I had hoped to find. Could find nothing but crappy bright yellow, plastic STANLEY boxes with a bunch of holes and plastic pegs for adjustments. Totally turned me off. I wanted the simple, quality metal box just like my grand dad had in his garage. This is the mitre box of my dreams to help me build my picture frames. Pay a little more, and get the best! thanks Firstinfo for your quality and workmanship.

Good Idea, Not Perfect
Bought this for small furniture trim and molding simple miters. I think steel would be better. My coping saw easily cut into the aluminum. Even being very slow and careful, it won't take long to compromise the cleaness of the angled cuts. Like the clamp feature. Good design, just needs to be more robust.

Slice and dice, small.
Can't complain. I bought the little miter box on accident. But I had a very particular project to do and it worked out well. I split the miter lengthwise. I drilled holes on the undrilled side. Lined them up and screwed them down at the proper distance for my project, a long plastic tail light. Worked great. The 90 degree slot fit a hacksaw blade nicely.

Watch Out: This Miter Box Bites (Literally!)
WARNING: The edges of the saw guides are razor-sharp, particularly where they cut through the extruded track for the hold down clamp. I picked up the box with a finger on one of these areas, felt a nick and found that I had a 1/4" slice into my finger tip. The box was anodized after the slots were cut, so I don't understand why they didn't de-bur the whole thing after cutting and before anodizing. Pros: The box is well made, and seems accurate, but see Cons. The hold-down (which is why I purchased the box) works well. Cons (in addition to the sharp edges): The slots are wide: the listing states "maximum thickness of blade is 1.2mm (0.04 inch), but my trusty Starrett feeler gauges says the slots are 0.066"/1.65mm [by the way, 0.040" = 1.02mm and 1.2mm = 0.047"]; my Buck Bros. "Professional" Miter Saw (steel back, not brass) has a 0.035" kerf (0.025" blade) which would have been perfect with a 0.040" slot. Bottom Line: I'm keeping the box, as the hold-down does what I needed; I will use fine grit cloth between the clamp and the guides to smooth the sharp edges in that area (and add a warning label). However, I'm only going to use it when I need the hold-down: the plastic miter boxes available from Lowes & Home Depot have narrower slots and fit perfectly after the first cut (less wear & tear or the saw blade, too); it looks like you need to make your own if you want a hardwood box.

good size for small aluminum moldings, tubing or plastic rod. can be mounted to a bench or table to make cutting easier. fairly precise straight and bevel cuts.

手のこでキレイに切れ、素材もアルミなので永く使えそう。商品はアルミの型材をほぼ切り放しの状態で、角が立っており、指を切るかもしれない。他のレビューが役に立ちました。使用前にエッジをヤスリで整える必要がありますが、商品のコスパはなかなか良いと思います。
