What blade for Chop Saw to make my own hoses?

[Waxman]

Hi everyone

I'm planning to begin making my own high pressure hoses. Part of the process is cutting the bulk hose to length.

I'm using this: https://www.sears.com/craftsman-7-1...HVf4qPcmpsNkaeu_TlxRsxinoCsX2AsYaAtO9EALw_wcB

question: What is the best blade to use on this saw to cut the hose?

Thanks!

I used to use a big cable style cutter like a limb cutter, but it distorted the hose too bad and didn't want to cut through all the SS braid cleanly. So I started using my Harbor Freight Metal Cutting Saw... https://www.harborfreight.com/14-in-3-12-hp-heavy-duty-cut-off-saw-62459.html

The metal cutting blades I use cut through the hose and braid without distorting or fraying. It cuts with ease!https://www.harborfreight.com/14-inch-chop-saw-blade-90135.html

You might try to find something similar in 7-1/4". Just don't go over the rated rpm of the blade. Your saw is 5000 rpm.

These will work:

5/8 arbor and rated at 8730 rpm....5/8 arbor is the same as your saw.

I use a small cordless mini grinder with a metal cut off wheel. Works great and very handy for many other things around the wash.

Oh good. I have one too. The hose machine is at another garage ( I work with them in the used car business), so I plan to leave the chop saw there so they can use it when they make hydraulic fittings.

If you don't already have the saw, you should get this: https://www.homedepot.com/p/Milwaukee-14-in-15-Amp-Abrasive-Cut-Off-Machine-6177-20/202983575

I do the same as Soapy. Hand Held 4.5" grinder with metal cutoff wheel.

I carry a grinder with a cutoff wheel for field repairs, but it's a lot more trouble than a chop saw, plus I have to clean up the ends sometimes to get the fitting into the hose. The chop saw is so much easier and faster and neater, and the blade lasts many years.

Same as they said. 4 1/2" Angle grinder with the metal cutoff wheels. Thinnest wheel possible. I wrap the hose tight with electrical tape where the cut is. And cut the middle of the tape. It helps keep the fraying down. Sometimes!!!

I prefer not to have specialty (single purpose) tools unless they're really necessary or I use them regularly, so I also use the 4 1/2" angle grinder with the thinnest metal wheel available.
I find the angle grinder to be one of the most versatile and useful tools I have. (I should add that to the "favorite tools" thread!)

Ditto on the 4-1/2" angle grinder being a handy tool. I have about 6 of them set up with a few spares on the shelf! Each with a different attachment. Flap Wheel, Grinder, Cutoff wheel, Diamond Wheel, cup wire wheel, and standard wire wheel....I get them when HF has them for $9.99....Even with the wire wheels, I've never burnt one up. If this is all I had, I'd definitely use it to cut the hose.

But since I also do some metal working, the 14" cutoff saw is a great tool to have in the shop...Its nice to have the clamp hold the hose while cutting.

You guys have missed the point of this thread. Waxman wants to know what wheel to use for HIS saw, not that we all use our right angle grinder. Pay attention class!!!

Oh, I use a right angle grinder too.

Yes I have an angle grinder too and it has seen alot of use!

The hose making machine is at a friend's garage. He makes hydraulic lines for firewood processors and other things / projects. We split the cost of the machine and I offered to bring a spare chop saw I had. I got it for free from a garage clean-out I did with a friend last Fall, so it's no big deal to buy a new blade and keep it with the hose crimper.

The Diablo isn't the thinnest blade, but it cuts fast and lasts a long time. Harbor Freight's cutoff blades are one of the best things they carry - they're thin and surprisingly durable. I don't know on 7" blades, but with 4 1/2" grinder cutoff wheels Makita are best when you factor cost, cutting speed and disk life. Lenox makes a diamond blade for cutting metal, it's expensive and slow to cut but it should last forever.

If you plan on occasionally cutting metal and need a straight cut, the Diablo will suit you well. Really thin blades will flex.

I use a Dewalt metal cutoff saw with the thinnest Dewalt blade when I cut my angle iron for my custom made album tables.
