This Milwaukee 8 in. Metal Cutting Circular Saw delivers faster, cooler, cleaner metal cutting. Forget the showers of hot metal chips and sparks that were once an aerial threat on the job. This saw shears with a virtually spark-free wake and cool, burr and scorch-free edges that don't require post-cut finishing. Metal shavings are effectively contained with a durable magnesium blade shield and channeled into the saw's integral chip tank. It makes tough cuts: up to 10 gauge sheets and 1/4 in. steel plate cuts all day, every day. Even more extreme cuts, up to 3/4 in. steel plates, are possible. Specially formulated cermet tip metallurgy and tooth geometry ensure these incredible blades cut faster, stay sharp longer and resist more impact, resulting in less blade changes.

  • Driven by a powerful 13 amp (1-3/4 max HP), 3700 RPM motor and equipped with a full grill of razor-sharp, cermet-tip teeth
  • Durable blade shield with integral chip tank deflects/collects hot chips and sparks
  • Plunge lever for fast, effective plunge cuts
  • Exclusive quick-release shield latch for fast waste disposal and blade changes
  • 2-9/16 in. cut depth for 1-pass cuts through most common materials
  • Dry-cut technology provides faster, cleaner, more affordable metal cutting
  • Cool cutting also means that materials can be handled almost immediately, reducing downtime
  • Premium cermet-tipped blades cut faster, cleaner and longer than other carbide-tipped or friction blades
  • 5-year limited warranty
  • Comes with carrying case

Rated 4.0 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by Goodbye cutting torch. We have 4 of these for everyday use in structural steel construction. Once the saw is engaged, it pretty much self feeds with little to no effort required to keep the cut straight. The saws have pulled off 5' long cuts in 2-1/2" thick mild steel plates - and continued to cut for a long time after. Works fine on grating, C channel and I beams. HSS tubes also no problem.

Rated 5.0 out of 5.0 by Wow! Had some trepidation the saw could do as advertised. It is every bit, and more. It cuts through a 3" channel iron like a circular saw through a 2X4! July 8, 2014
Rated 2.0 out of 5.0 by worst purchase I have made could have gotten alot more for my $$$ I was told to hone the blade prior to using it which I did with the third blade after loosing two. kinda works it will spend a lot of time in my shop on the shelf!! November 4, 2014
Rated 5.0 out of 5.0 by Cut thru-hardened AR 400 Plate with it! I bought it because I supply some hardened metals to the mining industry and I didn't want to lose a sale because some customer didn't have a plasma cutter to cut my plate. I found that I could easily cut 1/4" mild steel with a 70-72 Rc hard chrome coating on one side of the plate - and it left a nice smooth cut finish. Could also cut the same plate product but with a 1/4" thick through-hardened AR400 steel back - although at a reduced cutting rate. The tool manual doesn't advise this but I tried it because a customer said he could even cut AR500 w/ his cold-cutting saw, and I had good results with the 400 plate. I found that a deeper blade setting combined with a kind of "plunge-type action" worked much better on the hardened plate than the shallow 1/4" deep-er setting that the manual recommends. I thought it might damage or destroy the blade but it worked very well. I don't know what my eventual blade life will be but so far, it cuts the materials that I bought it for and I am very satisfied. December 28, 2012
Rated 5.0 out of 5.0 by Awesome!!!! Im a rig welder and I love this saw. I zoom thru grading and anything thinner than 1/4 plates even diamond plate. Has helped me do my job very well. I use my torch a lot less now. I dont like the blade it comes with because it wares out fast but I installed a evolution 8" blade and the saw is a monster. I laugh at 1/4 plate and grading all day... Very good saw July 8, 2012
