SE Custom Knife and Tool Posted February 20, 2019 Share Posted February 20, 2019 Hi. I am looking into getting a JET coldsaw, and I am looking at the non-ferrous model, but I will also be cutting steel. Can I put a ferrous blade in a saw that comes stock with a non-ferrous blade, or does a non-ferrous saw only work with non-ferrous blades?

ThomasPowers Posted February 20, 2019 Share Posted February 20, 2019 Any differences in speed or kwh? What does JET say when you ask them about their product? Quote Link to comment Share on other sites More sharing options...
Anachronist58 Posted February 20, 2019 Share Posted February 20, 2019 They might tell you that it would void your warranty, either before you purchase, or after it fails on you. Their website, on its face, implies a distinct difference between the two types. What Thomas said. He covered it quite well.

Frosty Posted February 20, 2019 Share Posted February 20, 2019 Welcome aboard, your sign in is WAY too clunky for a handle, can we call you something easier? If you'll put your general location in the header you might be surprised how many members live within visiting distance. All things being equal(ish) always go for the more powerful machine. Go with Thomas's advice, give Jet a call and find out the real bonafide poop. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted February 21, 2019 Share Posted February 21, 2019 Good Morning SE, Use a Ferous blade in one saw, Use a non-ferous blade in a completely different saw. Thermite is aluminum and iron/steel powder. You don't want to find out accidently what a Thermite fire is like. Sparks from cutting steel "could be" enough to give you a very bad day!! Don't mix the material in one saw!! Period!! Neil Quote Link to comment Share on other sites More sharing options...
SE Custom Knife and Tool Posted February 21, 2019 Author Share Posted February 21, 2019 Thanks for the reply ThomasPowers. The speed on the nonferrous saw is much higher. I have not asked JET about it, but I will do that now. As for KWH, I have no idea what KWH is, so if you could please clarify, that would be great! Have a nice day.

ThomasPowers Posted February 21, 2019 Share Posted February 21, 2019 Well if it runs at a higher speed then I would NOT try it on steel. KiloWatt Hours a unit of energy and often a good measurement of how big a motor is rather than stall horsepower beloved by sales people. the first hit when I googled it was Wikipedia: The kilowatt hour (symbol kWh, kW⋅h or kW h) is a unit of energy equal to 3.6 megajoules. If energy is transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt hours is equal to the power in kilowatts multiplied by the time in hours. Unit of: Energy Symbol: kW⋅h Unit system: Non-SI metric English Engineering units: ≈ 2,655,224 ft⋅lbf Quote Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted February 21, 2019 Share Posted February 21, 2019 Read up on speeds and feeds when cutting metals. Steels use much slower speeds than nonferrous does because nonferrous is a lot easier to cut. You could probably go the other way though and use the ferrous saw for nonferrous. It is usually better to go slower than faster when machining metals, but there are some exceptions. Quote Link to comment Share on other sites More sharing options...
Kozzy Posted February 21, 2019 Share Posted February 21, 2019 There is no single answer. Typically a cold saw for ferrous runs pretty slow speed, and that's usually based on blade diameter. However, there are now a new class of higher speed ferrous blades out there---designed to run about 1500 RPM for the typical saw and much higher for more specialized cutting. We run nonferrous saws on aluminum tubing at close to 7000 rpm with specialized blades that cut nearly burrless. So, as you can see there are more exceptions to the rule than there are rules. Except don't make thermite always applies. Many nonferrous saws are also built much lighter because the stress various parts typically see is lower--so you want to check out the differences before you assume you can cut 2" chrome moly shafting on that saw designed for aluminum just by using a lower speed or cutting more slowly.

I'm guilty of a serious brain xxxx forgetting that one. Don't mix metals. Good catch, thanks. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
