Product Description
The 6190-20 utilizes dry (a.k.a. "cold") cut technology which will cut on average three times faster than an abrasive machine and costs 1-1/2 times less to operate. The saw produces little to no sparks when cutting and leaves a virtually burr-free finish. The motor is a 15 amp, 4.8 max H.P. The base is a heavy-duty cast aluminum reinforced with a 1/4 in. steel plate. The vise and back fence is tool free. The horizontal D-handle provides optimum comfort whether the tool is on the ground or sitting on a bench. Includes 14-inch 72 Tooth Dry Cut Carbide Tipped Circular Saw Blade and Hex Key.

 Great for small home workshop November 30, 2008
Metal Tech
I purchased this after comparing the Dewalt & Porter Cable versions in person. The saw works great, the angle fence is easy to adjust. The stock stays put while cutting. Very easy to release tension on the vise. When the upper motor is in the locked down position it is well balanced for carrying. Like others have mentioned, this saw requires a lighter touch than an abrasive style chop saw. I've cut 3x3x1/4 steel tube with not much more than a light downward pressure. It is much faster to clean up the chips from this saw vs the dust from an abrasive style chop saw.
Great Saw October 31, 2008
RuNuts (I'm here)
I was using an abrasive saw for a few years as a hobbiest. I started looking at this saw and read reviews from every source I could find before deciding to purchase it.
It is a great saw. I have not experienced any issues with the blade. As the instructions state and other reviewers state, you HAVE to be aware of the cutting rate and force you place on the blade. Just like a drill bit, too much heat will kill this blade. I have run about a dozen cuts of small stuff.
Very clean cuts. No heat to speak of. Adjusting the fence for angle cuts is a breeze.
I would not have any reservations recommending this saw to a friend.

Metallurgy 101
LUBRICATION
There is not a common metal out there that does not require some sort of lubrication while it is being cut. Furthermore, there is not a material from which cutting blades are made which do not require the same. Having machined the most common metals in the industry - Steel (hot or cold rolled), Aluminum, Brass, Bronze, and Stainless Steel - I can say unequivocally that lubrication is a must for a great cut and long cutter life.
The harder the cutter material the longer it will last - that is why carbide lasts longer than high speed steel cutters. Regardless, all metals need lubrication to cut them.
HEAT
HEAT is the #1 killer of a cutting edge, HEAT is a product of FRICTION, and FRICTION is greatly reduced by two things: 1( LUBRICATION and 2) CUTTING SPEED for the material being cut. Aluminum can be cut much faster than Stainless Steel, Therefore, aluminum has a higher cutting speed than Stainless Steel.
HEAT is a double-edged sword. It will ruin the cutting edge of even the toughest materials and it can work-harden steels. Cutting the material too fast will produce too much heat and will effectively harden the material on the spot. This will,in turn, make it more difficult to cut the material requiring more pressure and produce more heat which will ruin the cutting edge on even the toughest cutting material - even carbide. If you need to do a bunch of cuts then do a few and let the blade cool down and resume when the blade has cooled.
MY SUGGESTIONS
When using Carbide to cut metals use a small amount of LUBRICATION on your cuts and SLOW DOWN! Use a cutting oil. (any oil - even WD-40 in a pinch),and don't force the blade through the material - let it find it's own pace through the material. If you do this I guarantee you that your blades will last much longer and your cuts will be truer.
The term "Dry-Cut" really means "Dull Blades" - use lubricant.

A great saw and blade life is excellent for me January 5, 2008

Unlike many of the other reviewers, I have no compliant about the blade life. I purchased my saw in December of 2005 and use it for my business. I am on the original blade and have made over 2,000 cuts with it. Mostly I cut mild steel tubing, or aluminum structural. But lately I've been cutting 4x1" aluminum jig plate and 1.5" stainless. Perhaps other reviewers are having blade life problems because they use it like an abrasive chop saw. This dry cut saw needs to be run differently! The teeth on the blade are C6 carbide. If you use too much feed pressure the teeth will get knocked off or shatter.
Overall I love the saw and it has saved me at least a $1000 in deburring.
