Prazi 18" Beam Cutter Attachment for Circular Saws – for 7-1/4"-8-1/2" WormDrive Saws – American Owned Company – Increase Cut Depth from 2-1/2” to 18”

This thing is amazing ... yes a jig saw can doing the same job but would take 10 x as long. I am surprized on the accuracy and how smooth the cuts are. You will still need to sand the rough cut but what a time saver. I've been using this product to cut 8" x 8" white oak timbers and it sure beats buying that $4000 hand bandsaw. After about 10 or so cuts you will need to retighten the chain (just looses the screw, grab the bar and pull it down tight, and tighten the screw). After 40 cuts like any chain, you should take a file to sharpen the edges.

After much research decided on the Prazi PR-7000 for my Makita 5377 MG. Was prepared for a multi-page installation thesis that would make a research engineer happy but was pleasantly surprised at the clarity and brevity of the instructions, that made me happy.With a small amount of fiddling, and a couple of texts to Bob & Michelle to confirm some language used, since I'm kinda nerdy on that stuff, everything fit as described. Bob & Michelle were very responsive.Cut and fitted some railroad ties including a 45 degree miter end cut. See pics. Worked great, cut straight and fast for the application.I think it's a great product!Thanks PRAZI.

Finally got to use my beam cutter. Cut 3 stair stringers at the same time from from some 2" thick white pine that I milled from a dead fall. Couldn't be more pleased. Easily attached to my 50 year old Craftsman circular saw. Does not have a chain oiler, so i got a squirt can and filled it with bar and chain oil to lube the bar and chain.

The models listed on the package when it arrived for compatibility is limited and saws are no longer sold. I can't seem to get an answer from the company if my current model of Makita will work. I'm probably sending it back for a refund. Great idea, but no idea if it's safe to use with my saw and can't find out. They need to update their material or the tool itself to include a model safe to use with current models of saws out there.I ended up keeping it and giving it a try. It felt a bit risky, but I gave it a go anyway with my fantastic Makita cordless. It worked well and only knocked the score down a bit for poor communication from Prazi support.

Can’t find a better beam cutter on the market. Well pleased with the results . Advice anyone looking for a beam cutter to purchase this brand.Top of the line product.

I bought it as a gift. I haven't had a complaintsoooo...

Just no.Cuts great first cut unfortunately every single bolt and screw will rattle out guess they don’t believe in locktite. After 2nd cut chain was loose went to tighten and snapped tensioning bolt off. Turns out the chain tension bolt’s threads are machined into soft aluminum and will strip out when you go to tighten it with minimal force. That was after the screws for riving knife rattled out and chain cut into it . They charge twice as much to build it in the USA then use the same cheap parts as the harbor freight model . Sent pictures of bolt stripped out they offered to replace if I paid for it. Sorry just gonna return

I purchased the Prazi 7000 to go on a Skil 81/4" saw. It took me about 30 min to set the Prazi on the Skilsaw, being you have to take the blade guard off of the Skill worm drive saw. I have a large timber beam project I took on at my home and have to make approximately 200 crosscuts, miter cuts and lap joints on 6 X 10, 6 X 8, 6 x6 and 4x6 cypress beams. I had a few questions when thinking about purchasing this tool rather than using my 16" beam saw. I called Bob on 3 separate occasions, and he was quick to answer the phone and give me the guidance on what I needed and any assembly questions.After assembly and alignment of the saw I crosscut a 6"x10" beam and it was like butter to cut, and the face was flat and straight even with no guide! I have to make over 25 lap joints on my 4" x 6" purlins. I made another lap joint test cut on a 4 x 6, again by free hand and it wasn't perfect but with a guide it would have been, and it only took less than a minute. If the rest of my project goes as good as the test cuts, this tool will save me hours upon hours of time.I'm giving this tool 5 stars because of price point, ease of assembly and use and something else that is hard to find these days is great customer service. Thanks Bob!!1
