Why is it called a cold saw?

Why is it called a cold saw?

Cold saws don’t require flood coolant because the heat generated by the cutting action is transferred to the chips. The chips are ejected by centrifugal forces of the rotating blade. This process allows both the blade and the cut material to remain cool, hence the name “cold saws”—but beware of the chips.

What is the purpose of a cold saw?

A cold saw is a circular saw designed to cut metal which uses a toothed blade to transfer the heat generated by cutting to the chips created by the saw blade, allowing both the blade and material being cut to remain cool.

What is the difference between a cold saw and a chop saw?

The cold saw has a toothed, high speed steel blade where a chop saw only has an abrasive wheel. The best part of an HSS blade is that it can be re-sharpened. If the sharpening process is done correctly, you can get one blade re-sharpened 15 to 20 times before the diameter shrinks too far to be used on your machine.

Can I put a carbide blade on my chop saw?

Chop saws designed for abrasive wheels aren’t compatible with slower-speed (RPM) saws that use carbide-tipped blades for cutting various metals. You can find some steel blades designed for higher-speed saws.

What are the disadvantages of a cold saw?

In addition, cold saws usually cause significant kerf loss, which translates into lost production and higher costs. While cold sawing can be use to cut most ferrous and non-ferrous alloys, it is not recommended for very hard metals — specifically, those harder than the saw itself.

How many speeds can be used on a cold saw?

When you attach a cold saw blades to a power saw with two (2) speeds, regulate according to the material you are cutting. When cutting stainless steel, use a much lower speed. When cutting metals, use a much higher speed. The speed list could be surface feet per minute (SFPM) or the regular RPM.

How long do cold cut saw blades last?

On average, a typical cold saw blade should last at least six months. Damaged teeth. Typically, a cold saw blade can complete between 800 to 1000 cuts before totally wearing out. Also, during their lifespan, you can sharpen them up to 30 to 40 times.

Can you use a cut off wheel on a miter saw?

As long as the RPM of your miter saw is within the appropriate range of the cutoff wheel, I see no reason not to. Obviously (as already stated) there’s always a risk of the wheel failing.

What type of PPE should you wear while using a cold saw?

PERSONAL PROTECTIVE EQUIPMENT Safety glasses must be worn at all times in work areas. Long and loose hair must be contained. Hearing protection must be worn. Sturdy footwear must be worn at all times in work areas.

Can you cut stainless with a cold saw?

Solid HSS cold saw blades specifically made to cut stainless steel. TCT cold saw blades are the best use with metals. However, Ferrous metals are harder than non-ferrous metals, and this allows you to use TCT ferrous metal cutting cold saw blade to cut non-ferrous metals.

Are Diablo blades worth it?

Diablo blades are available in a wide selection of sizes and styles and are easy to find online and locally at Home Depot. The consensus is that Diablo saw blades balance great quality with excellent value, and are a good choice when replacing or upgrading the OEM blades that are often bundled with new saws.
