POWERTEC 4'' x 36" Dust Collection Hose, Flexible 4 Inch Dust Collector Hose for Table Saw, Drill Press, Woodworking and Wood Shop Dust Collection System (70128)

The hose was of good construction. I have not had a chance to use it on my project but I’m sure it will do what I intended to do.

I'm really pleased with this product. I purchased it to setup a semi-rigid exhaust system for my DW735 planer. I go right from the exhaust into a trash can. It works perfectly for this task. Also, just in case it's not clear from the description, this hose isn't really flexible. Basically, you bend it to the shape that you want, and then it holds that position. Would definitely recommend. ***My Rating Criteria*** Build Quality(36.0%) - 5.0 Stars Efficacy(54.0%) - 5.0 Stars Post-Sale Support(0.0%) - n/a Packaging/Presentation(10.0%) - 5.0 Stars WEIGHTED AVERAGE(100.0%) - 5.0 STARS

I ordered this hose to replace a hose that had torn inside my Jet table saw. The hose hooks up to the blade shroud to pull dust out of the table saw. The old hose was torn for awhile because when I opened the base cabinet it was full of sawdust. I tried another coil spring hose but for some reason the hose tore in another place. I think my hose clamps (universal types) poked the hose and tore it. After receiving this hose I noticed it was very stiff, but it was like an accordion and could be pulled and pushed to greater or lesser lengths. I tested the hose on my saw, which has connections for a 4 inch hose, and it went on very well. Then I tried to get my old 4 inch hose connectors onto the hose and they didn’t fit. The accordion style of the hose makes the body of the hose larger than the coil type I was using. I had to buy larger hose clamps. It is installed now and the dust collector works very well. It seems to pull more dust away from the blade area than before, but I think the old hose had been torn for a long time – maybe since I bought the saw. I have been consistently cleaning sawdust out of the cabinet area and probably never looked for a tear. Or if I did look I didn’t see it in the dusk like light conditions inside the saw cabinet. The hose’s adjustable length was a lifesaver. I tried it with the saw full up and down, and all the way over to 45 degrees and no problems. It should work well. Be aware that the hose isn’t soft and flexible like many of the see through coil and plastic types. It is somewhat stiff, although it still bends because of the accordion construction. AD2

This review is for the POWERTEC 70128 4-Inch Flexible Dust Collection Hose, Left Spiral, Black incase amazon pastes it under other products... It's a hose. You bend it and it says bent for the most part. The bend is full and round, doesn't fold up like the less expensive vinyl ducting which I would assume would give better airflow. I will be using it to duct solder fumes away from my desk so being able to reposition it and have it keep it's shape is a big plus. So far happy with it, just have to finish 3d printing the window vent and will put it to work.

This collection hose is actually better than I thought because not only is it flexible it can be set in different curves and stays that way. I was thinking it was more flimsily like a dryer connection hose . you can pose this hose in a curve or stretched out or shrunk in position and it stays in that formation. Its more stiff and sturdy than I thought. more like a pvc pipe that you can shape the way you want it to be rather than a hose that changes shape constantly.

Looks like an ordinary pipe and it doesn't stretch much. But It does hold its orientation to a degree more than standard dust hoses. I am using this + a rockler 51387 DUST HOSE MOUNTING BRACKET + DCT 4in Plastic Pipe Threaded Quick Connect Adaptor Coupler on to connect this to my dust collection system with a Rockler quick change 4 inch hose attached to add dust collection for my wen drill press. It should work. hooks up ok. We'll see if the ribbed pipe material maintains good suction. As always you need to hope your adaptors, couplers fit. I had to sand the adaptor with my belt sander to fit to my 4 inch dust right quick change handle.

Very nice unit. Feels natural in the hand and works quite well. Functions are easy to figure out without instructions. Used on my dust collector, I was able to calculate the CFM produced. I used the formula CFM = Area in ft^2/min x Velocity in ft/min. Area = (Dia in inches/24)^2 x Pi (3.14). The velocity is measured by the meter. Useful areas are 6 in = 0.1963 ft^2. 5 in = 0.1364 ft^2. 4 in = 0.0873 ft^2. 2.5 in = 0.0341. The ^ symbol means squared. Use your measured velocity in ft/min multiplied by the area calculated above.

This hose is heavy duty, not floppy thin. When you bend it, it stays in place. You don't need elbows.

There is nothing to dislike. It is reliable and does the job for which I ordered it. It is attached to a DeWalt thicknesser and as you can imagine the chips that come out could make an awful mess if not for the dust extraction unit I devised and needs the 4 inch tubing to accommodate the amount of debris that is ejected by the machine that has it's own extraction fan.

Lo utilizamos para un colector de polvo y fue exactamente lo esperado de acuerdo a la descripción del producto. Gracias !

Created a solid connection between my dust extractor and dust seperator. It has also improved the airflow

I have just received this hose but I am very pleased with the hose although it was quite hard to fit onto my numeric dust collector and my Rockler quick fit handle but so far I am very pleased and I would highly recommend.

I needed that for dust collection. Found the idea on YouTube and followed the link. Yesterday, I found the same item, 3 times longer and half the price in a hardware store. I used it so I cannot return it. Great product though.
