Prazi 12" Beam Cutter Attachment for Non-Worm Circular Saws – Model PR2700 for 7-1/4" Circular Saws, Non-Worm Drive – American Owned Company – Increase Cut Depth from 2-1/2” to 12”

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.

This product has worked really well for us as we build many structures out of timber. The install was easy, especially after learning the slide guard needed removed, and it cut well straight out of the box to the point where it didn’t even need the chain adjusted before using. Seems well-built and well thought-out!

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.

I had intended to install this on a Rigid R32104 Worm Drive, mostly because of their lifetime warranty but it would not fit. After a conversation with Bob at Prazi I decide to mount it on a Skilsaw SPT 77. This worked out very well and installation was very easy with the exception of having to remove the lower blade guard from the saw. Adjustment of the Prazi Beam cutter was fairly easy and saw now cuts great. Very happy with the purchase and enjoyed talking with Bob at Prazi customer service.

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 do a lot of wood working. From mill work to rough carpentry to finish work and crafts this product has helped in a few stages along that process.I use this in conjunction with a DeWalt DWS535B worm drive saw for cutting pre made beams and to cut end grain from logs and thicker slabs. I’ve also used this with a ripping chain to cut slabs with an Alaskan mill.-The Chain: Oregon 3/8 low pro- .050 kerf- 91 drive links.-The Bar: 3/8LP- 18” .050- but is stamped specifying a 63 drive link chain. ??Both easily replaceable as basic chainsaw parts.In my experience the chain came very dull. Nothing that couldn’t be fixed in a short period with a hand file. Carry silicone spray or oil as a lubricant in longer cuts to keep it running smooth and cool. Also take your time. Prazi says you don’t need a chain oiler because the lower rpm of worm saws but an 18” bar through some dry hardwoods will most certainly overheat and over work your equipment.The safety (yellow) bar flexes easily and will cause the finish to chip away around the two hex bolts fastening it. I opted to remove this because the safety bar became more of a hinderance to me than what I deemed “safe”.Note: This saw works in opposite rotation as compared to a chainsaw and if you encounter kick back it’s going to come up between the legs as opposed to coming at your head/upper body.Installation is fairly easy if you’re knowledgeable around this stuff. If you have difficulty, look up a video. The directions that come with this are not precise, clear or displayed well for the many different makes of worm drive saws.It is likely you will have to remove the safety shroud from the saw completely or cut a large section out with a grinder. This is the case for a Dewalt DWS535B. Make sure to keep track of the springs and internals if you plan to change this back to a 7 1/4” circ saw.Overall this is a nice product that fits a niche for me. I have cut over 50 board foot and it is holding up so far. Time will tell if it is durable enough to make up the sticker price.It is not a highly crafted or machined item and you will more than likely find blemishes. You are paying the premium for the Mount. All attached accessories are basic run of the mill chainsaw part #s.Post questions and I’ll do my best to follow it up.

Excellent customer service. Beam Cutter tool manufactured to the highest standards. Paired with a Bosch CS10 motor, the tool efficiently and accurately cuts all manner of landscape timbers and wooden posts.
