Can You Attach a Flexshaft Tool to a Drill Press Chuck

I was tired of the depression power of my dremel clone, information technology kept stalling even with calorie-free pressure. The 100W just doesn't cut it for rougher jobs.
So I started looking for a more powerful version, merely other alternatives were either expensive or even so low powered.

While looking around in the local DIY shop I saw a flexible drill extension and thought to myself, why don't I attach that to my belt grinder...
So I bought the extension and an SDS chuck then I could fit it onto my multiwheel grinding head.

The contact wheels on the Aly maxi grinder are kept on with a small-scale bolt roughly the imperial equivalent of a metric m8. Replacing that bolt with the SDS chuck would allow me to utilise the extension as a dremel flexi shaft. I didn't have an purple tap & dice gear up though so I tapped the hole and threaded the bolt to m8.

Adjacent the SDS adapter needed to exist m8 as well so I ground it down until it was nigh the same diameter as the commodities and threaded that as well. I wasn't able to get it perfectly straight unfortunately so it wobbles a fleck while spinning, a lathe would have come in handy there. Putting information technology in the drill press would take damaged the threads on the other side, while the nut was too big to chuck upward.

And so all I needed to do now was switch the grinding head commodities for the chuck and attach the extension.

Information technology can take shafts upwards to 6mm and then I tin employ dremel $.25 or larger ones like a rotary rasp.

I've got Aly'south directly bulldoze maxi grinder so at 100 hz the motor spins at 2850rpm (Aly and the grinders he makes can be constitute on British Blades btw). With the iv" bulldoze wheel, speed settings are easiest to read when using the 35mm contact bicycle on the grinding head. This gives me a max speed of 9818 rpm which makes 1 hz merely a tad less than 100rpm. This extension can but handle 3600rpm though and then 36 hz is the maximum safe speed, but if I tin observe a way to attach the dremel flexi shaft, I could get up to 100 hz no problem.

So what I ended up with was a 1500 Watt variable speed dremel. There are a few flaws of course, such as portability and a lower maximum speed, merely overall it works quite well and I very much doubt I'll be able to stall this.

I besides got the suggestion to put a polishing mop on there by FGYT on BB, making information technology even more than versatile. I already have a 1 horse buffer with 8" mops, simply information technology has a fixed speed of 2950rpm and so the vfd should be handy for more than delicate things.

Has anyone else done anything like?
