Dremel 402 Mandrel

Dremel 402 Mandrel

1 8″ shank. Mandrel to be applied with all cutting wheels, sanding discs, and polishing wheels.

A shank with a screw-like head. Used principally with Dremel polishing bits and accessories. For best results, insert the mandrel all the way into the tool and then back it out somewhat before tightening down. This provides a great deal of shank for the collet or chuck to hold onto. Simply remove the screw, line up a cut-off wheel or sanding band over the hole in the shank, and replace and tighten the screw.

Alright, but pesty..
By Michael Bremer
These work for what they are but they are kind of a pain to change out with the little set screw. If you are doing any heavier responsibility cutting with the wheels suppose it to be beauteous time consuming among breaking the wheels and the time it takes to unscrew the screw to put a new wheel on and screw it back in. Shoot for the fiberglass reinforced wheels to use in combining with this they are heavier responsibility then the so called “heavy duty” cutting wheels.

a little pricey
By J.Twain
Get it for back-up. The price is a little high for a lot of little metal like this, but anyway when you want something, you have to pay for it. It is just a simple mandrel, and It is 100% precisely the same mandrel that comes with my Black & Decker RTX-B 3 Speed RTX Rotary Tool. They in all probability have made it in China for less than 10 cents.

Over-priced, totally.

Don’t cut the keeping screw head in half!
By K. Tacia
For a heap of odd reason dremel doesn’t provide washers to aid hold cutting wheels in place. The original cutting wheel I used ground out it’s own center hole too big to keep the cutting wheel even. I did manage to cut through my rusty bold, but had to replace the wheel because of the center hole damage.

The second cutting wheel cut right through the teeny tiny screw keeping the wheel on the tool.

I was hoping that dremel made something better than this, but apparently not. From what I may asertain I am supposed to stock up on dremel mandrel screw downs at 3$ a pop and let it cut through it’s own keeping screw.

It is a pain to tighten this thing down because the screw is so small. The cutting wheels are so fragile I am affraid I am going to shatter the wheel if it’s down two tight. If it’s not down tight sufficient even though then it will cut the keeping screw or grind out a big hole in the center of the wheel. (Can we get around to genuinely cutting the material in the project?)

Also, be careful when tightening this down. If your screw driver slips and goes past the screw too fast it will shatter the cutting wheel.

It astounds me that they would have such an unstable method for keeping the cutting wheel in place. I would have thought after the number of years on the market they have had they would have bettered on the method of keeping these wheels in place. A wide flat surface such as washers or a flang of some kind on the end of the tool to support the wheel would be a big improvement.
