Large 16AN Stainless Braided Hose - best cutting method

[OkieRocket]

Sorry if I am posting this in the wrong area of the Forum..... If so, my apologies.

Regarding cutting 16AN Fragola 3000 series Steel Braided Hose:

On smaller 3000 series Hose (i.e., 6AN – 12AN), I usually use a large pair of Klein Cable Cutters with approx. 20”+ length Handles. This works great, but I am getting ready to cut some much larger Fragola 16AN size 3000 Hose and don’t want to “tear it up.” I think the Klein Cutters will be way too small for this job.

On smaller Fragola AN Hose, I’ve also tried Hacksawing and even Chop Saw cutting using an Abrasive Blade, but don’t really like the Chop Saw route, due to excessive debris/mess, etc. In one case a while back (on a 12AN stainless braided Hose that came from Aerospace Engineering with a new Vacuum Pump I had purchased, I used an Abrasive Chop Saw and was surprised to find that the inner rubber Hose had separated from the outer stainless braiding!....It looked like the “glue”?? or bonding Tape?? “broke down,” due to the excessive heat of the cutting operation and failed. The inner Hose would then actually slide back and forth separately from each other….For this reason, I am always suspect on cutting anyone’s Stainless Steel braided Hose using an abrasive Chop Saw…Does anyone know if this a problem with Fragola Hose, or if using an abrasive Chop Saw, will the Fragola Hose (or other high quality Hose) not “separate” due to the high heat generated when cutting?

What is the “best method” to use when cutting the larger 16AN size Fragola 3000 Hose? Would appreciate any thoughts on this.

For that size of hose, find a local hydraulic hose shop and have them cut it for you. The hand tools sold by AllStar and others are a hit/miss.
The dedicated circular blades are expensive, starting at $150.00 + per blade.

In my case, I use a high-speed Dremel tool with an EZ Lock dedicated circular blade for stainless steel. I tape the end of the hose, put the appropriate size long socket at the end of the hose, draw a line around the hose, and take my time cutting the hose. The socket prevents the separation of the inner core as you cut the end of the hose and the tape prevents fraying by keeping the braid together.

The circular blade I use is Dremel P/N Max Life EZ506HP, High-Performance Premium Metal Cutting Wheel.

I use a Greenlee 718 cable cutter on all my braided hose including -16.

I usually sharpen the blades with a honing stone before cutting. It works perfectly on stainless and even nylon. If I get any fraying, I shape the end with the broad side of a cut off wheel.

I usually insert a wooden dowel inside the hole of the hose that is close to the diameter of the hole, not to tight but not too loose, a little white grease helps. This keeps the shape of the hose intact. Electrical tape on the outside, cut using the method of your choice, Dremel is my favorite. After the cut is made take an air hose and blow out what’s left of the dowel. WARNING: what’s left of the dowel in the hose is a projectile!
Obviously if you want to make a cut in the middle of a 12 foot hose this doesn’t work but it works great to clean up your previous cuts.
Good luck

Tape it and air grinder with cut off wheel. Cut it direction of cutter rotation and will come out clean. Air hose to clean and ready for fitting.

THANKS for all of the great Tips and Info. guys! I really appreciate the help!

Metabo or other thin cut off blade will work fine too

[Jeff Stout]

Do you need any 90's or straight ends? I have brand ones in the red blue color. Half of cost plus shipping.

Thanks for the "deal" Jeff, but I already have my Fittings. I appreciate the bargain though!

I have the redhorse large cutter $$ one chop and your done, just one wrap with masking tape for fraying
