cold saws

[Ironhorse74]

I have been looking at cold saws. I will be cutting mostly steel tube and angles but want the ability to cut some non ferrous in the future. This will be in a serious home shop but not a professional shop. Always been a Dewalt guy so the DW872 jumps out. Since I don't know what I don't know. Is there another saw in that price range I should consider?

A DW872 is not what is usually called a cold saw. Here's a couple of links to a real cold saw:

I have a Ryobi saw that is similar to the DeWalt saw that you mentioned and it works just fine. I also have a metal cutting bandsaw and I MUCH prefer the bandsaw.

I am trying to figure out the difference between the DW872 and what you posted. From a specifications they are very close. Perhaps you could explain why the DW872 is not a cold saw.

This, I have the Rage saw, chips are awful, found a used Fem Saw, much better...

My understanding is that a cold cut saw employs liquid cooling for the work piece, whereas a dry cut saw doesn't use lubricant.

Cold Saw: Very industrial, Very Expensive and uses a steel blade with coolant always.
Dry Cut Saw: Moderately priced, Uses a carbide toothed blade and NO coolant. The best of these is made by M. K. Morse.

The main difference is blade RPM and torque. A proper cold spins at around 44 RPM and had a gear reduction off the motor for lots of torque. They use a solid HSS blade, and have full flood coolant, a nice vise, and usually a swivel head.

A dry cut saw on the other hand, is basically a nicer abrasive cutoff saw. They spin at a much higher rpm and are way cheaper. They don't come with much in the way of user features.

Get a band saw.

Although dry cut saws, and even the more stout wood miter saws are great for cutting aluminum extrusion.
