DremelFlex Shaft Rotary Tool Attachment with Comfort Grip and 36” Long Cable - Engraver, Polisher, and Mini Sander- Ideal for Detail Metal Engraving, Wood Carving, and Jewelry Polishing, 225-02

I needed a setup to allow me to enlarge an opening on the side of a Larrivee LV-05 acoustic guitar. The instrument was nearly 25 years old and in immaculate condition, but the pre-amp needed to be replaced. The work required was delicate and the hand piece of the Flex-Shaft Attachment was exactly what I needed. I had to commandeer a kitchen counter for a work space, used a camera tripod to hang the Dremel tool. That gave just the right distance without any severe bends to contend with. Used the Dremel 4486 keyless chuck to hold the drill bit to create new holes for the pre-amp mounting and used a carbide burr from Fotybei to carefully enlarge the pre-amp opening where needed.I will be using the flex shaft with a carbide burr to get into a hard to reach spot for grinding out the axle rivet on my Travelpro luggage wheels.

This flex shaft DOES fit both WEN rotary tool models, i.e. the blue and the orange. The shaft wore out on my blue one because I just carve so many highly desirable, beautiful pieces of majestic art. No big deal. Anyway, I couldn't find a well reviewed replacement flex shaft that specifically stated it fit the WEN models so I took a chance on this well reviewed Dremel flex shaft and...it fits! I am so happy it does because this is a much nicer flex shaft than what you get with either of the WENs. This Dremel shaft is much more comfortable to hold, insulates much better against heat, cuts vibration until it is virtually negligible, and is startlingly quiet. Listen, I like WEN tools. Along with the aforementioned blue and orange rotary tools, I own around a half dozen of WEN's power tools. They are impressively adequate tools given their low price point. However, if I am being honest, the WEN shafts are total garbage in comparison to this Dremel flex shaft. I actually just ordered another one for my other WEN rotary tool even though its flex shaft is still in working order. The only CON: the Dremel flex shaft is significantly shorter than the WEN flex shaft but, just like I scream at myself in the mirror before bed every night, size isn't the only thing that matters. This is a well made, heavy duty shaft whose shortcomings in length are more than out distanced by the quality of its form and function. I guess Dremel might be worth the extra expense after all.

as described however after reading other reviews I pulled it apart and cleaned it up and added my own synthetic grease on cable and in end unit. Make sure it stays tight on your Dremel tool and don't force the tool to do more than it designed to do. Cable isn'tthe size of a cable in a weed trimer.

I'm using the Dremel 3000.The button lock on the flex shaft tool may temporarily malfunction or catch within a half-locked position, causing significant strain on the flex shaft tool shaft and Dremel motor. May also hear the clicking noise of the button shaft lock on the flex shaft tool handle rattling. To fix, stop the tool and operate the flex shaft tool lock button thoroughly several times, ensuring adequate locking/unlocking of the shaft. I also squirted a little "Dry Lube" lubricant into the lock button mechanism, ensuring the button had enough good lubricant.Again, symptoms of the flex shaft tool lock button malfunctioning:1) May hear a constant rattling/clicking like noise from the flex shaft tool handle, near the flex shaft tool shaft lock button.2) When operating the Dremel motor, may need require increasing torque greater than 2 or greater than 4, for the shaft to start rotating.Another con, the directions are extremely very small fine print, too small for us older folks to read, including multiple languages. Should be a manual/pamphlet for each language... cheap manufacturing of the instructions, and yet they still desire the end user read and follow safety instruction?Directions also seem to omit explicitly indicating to switch the shaft nut with the included shaft nut! I thought the manufacturer was being nice, and including extra parts.... foolish me! The included shaft nut has the required square female end, for properly engaging with the flex shaft.Other than the previously mentioned, everything else works as should, making using the tool much easier with likely far less hand fatigue due to being narrower and more light weight.
