Thread: 24V drill doctor

Product description down the bottom of page states "...with 240V UK 3-pin plug". I would suggest that it is actually a 240v unit.
Same unit as what can be obtained locally but with UK plug.

Then, you go to a store that sells suitcases. They have all sorts of accessories for travel.
Including an absolutely crazy range of adapter electrical plugs for every system on earth.

Think of electricity as a waterfall. The height is the voltage and the amps are how much water is flowing.
A drill grinder shouldn't need much amps to do the work, no matter what voltage the motor runs on.

Google search shows no relevant results for a 24V model, 99% sure it's a typo

From the DD website

"Using a 115V machine in a location with 230V power sources voids the warranty."

Is the price also a typo???

At that price I'd be going for something like one of these instead.

That will also hold bits up to 3/4"

Use a mini Jacobs chuck to hold bits <1/8"

There are fancier versions of that jig design if that takes your fancy...

If you need to to sharpen carbide tips, add a diamond disc to the side of your bench grinder wheel.

They are cheap enough but getting one with the right arbor size for your grinder is the only challenge there.

Still have my old one of those. Found it when I was around at my workshop this morning, at the back of a bottom drawer.

Happy to part with it if interested

Thanks all I'll probably go ahead with the amazon purchase as its almost $200 less than locally sourced unit. It does split point which is why I want it

I can understand their CYA attitude about this, however I have a nice 240V-110V 1200VA isolated stepdown transformer at home that has been powering my US sourced Mak 18V Lithium chargers etc since a year before this Mak range was released for sale in OZ, plus some vintage sewing machines from US and a 115V DD750X for the past 5 years without any issues.

Of course, if you self import gear from overseas, you generally cut yourself off from warranty support anyway, the OS suppliers don't want to know with the shipping costs involved, and anyone commercially importing most likely does not have the 115V specific parts to offer warranty service if needed, or to even supply to you on a paid basis.

I understand this can work well for some people but not everyone.

When a relative was returning from the US after living there for many years he had his removal costs covered by the mob he worked for. I was visiting him just before he moved and he offered to bring more or less anything I liked back - apart from household effects he was shipping 3 motor bikes plus most of the portable workshop gear. So I went shopping and bought a bunch of decent hand tools, large squares and tools boxes. I looked long and hard at cordless power tools (it was pre "skin" days) - very attractive, but in the end I decided against it. Even though I already had several 240 - 100V transformers under my house I have very little room in my shed and the last thing I needed was a transformer cluttering up my battery charging bench in the shed.

My brother bought back a heap of 110V corded tools and set up a beefy transformer and even ran a dedicated 110V line around his shed and set up 2 dedicated 110V GPOs at each end of the shed. About a year later he had to move house and the 110V corded gear sat in a corner gathering dust and he gave up and went and bought 240v tools.

Well you won't be disappointed, that's why I bought mine. I did some rudimentary testing using some scales and it takes approximately 40% less effort to drill steel with the split point bits.

I wouldn't have bothered doing it for bulky tools etc, but for the Mak chargers it was worthwhile since the gear wasn't available here at the time. I then bought a surplus thumping great toroidal power tranny (twin 55V secondaries) intended for a 4 channel power amp and mounted it into a surplus 19in rack case that I had left from my PA building days, complete with switches, indicators, fuses etc,. Output is a US 6 way power strip on the front panel. It was mounted on a shelf above the chargers so didn't really need extra space, but has lived on a packing case behind the chargers since moving into the new shed last year, but will get it's own shelf again when the shed fit out is completed. Meanwhile the DD shares space on the case with the chargers. HM recently bought a Singer featherweight sewing machine that turned out to have come across the Pacific in the 60's so 110V, and the transformer is currently powering that inside the house, sitting on the floor of her sewing room.

Quertyu has settled on his preferred solution for his needs.

However, if there is anyone that has less readies, some existing setup, and less need to get the job done quickly, the following approach to split points may work for them. See post #8.
