FIRSTINFO H5442 Metal Small Aluminum Miter Box 5.5 Inch Small Tiny Mitre Box for Manual Saw for Hand Saw 3 Cutting Angles

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 usefulCons:*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 starsIf 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.

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!

Update:1) Looks like some kind of barrel nut is used in the knob.2) The pad is plastic, not rubber. It also rotate, but it is stiff. You have to hold the pad in the desired position while screwing down the knob.Original:I really like the clamp. I wish it came with two clamps. The knob could be improved.1) It's plastic.2) It's likely only plastic threads are holding the bolt.3) If the knob is over-tightened then it will likely strip the plastic threads.4) The rubber pad should rotate independently, like on a traditional C-clamp.Don't over tighten the knob and maybe it will last. However, even if the knob breaks, creating a replacement knob shouldn't be too hard.Lastly, the slots for the blade are 1.4mm wide (as far as I can tell).

good quality well made

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.

I thought this was gonna be great however, the cheap aluminum frame it supposed to guide your hacksaw actually got cut into duringUse Negating the whole purpose of having a guide.

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.

My saw cut into it the 1st time I used it, so now that angle is off. Garbage.
