HILDA 220 Volt 400 watt electric rotary grinder - cheap TPG ? 

It's really good. Nothing else comes close for the money (in electric tools).

I know the feeling. I like the fact that this grinder will swing that 75 mm cutting disc equally as well as my larger air die grinder. It's got plenty of power. Cheers Rob

Hi Glenn, I'd definitely buy one if Banggood hadn't helped out. Plus these are not in any local hardware/tool shops in my area, which is a bit strange considering they have heaps of everything else. Maybe they haven't caught on yet ? Cheers Rob

Rob, that price would still be excellent if it were available in 110V. I have not seen anything of that size with a chuck.

That lower pirce is for the lower watt, I think its the 180w version)

Hi Charles, Glad to hear you're pleased with it. I'm always a bit worried that my appraisal won't meet people expectations. Those power converters look to be the business, and a cheap way around the USA workshop problem. I'm surprised more people don't use them. Be sure to play around with different grinding mediums and techniques before you tackle anything expensive with the TPG. Cheers Rob

I will follow your advice for sure. I have an $8 MT3-MT4 adapter from Banggood that's about 15 thou out that'll be perfect for a trial run.

Hi Tim, Vibration is not a big issue, but it tingles when running, suggesting either armature out of balance slightly or it could be from 50 Hz pulsing. It's similar to what an angle grinder does and these are basically from the same family. There is no apparent looseness or runout in the bearings - all tight there. Cheers Rob

Es una buena maquina. El mandril lo hace muy útil para sujetar una amplia gama de tamaños de vástago donde una pinza no puede. Usted no será decepcionado. Saludos Rob

Ha Ha. Might have to open my own store. Cheers Rob

Just need some cool weather - absolute shocker here lately at mid 40C.

Glad we don't get those temps. This morning there was some fresh snow. I don't think it will stay but the temp in my workshop is down to 4C. And that below my comfort zone :)

They are awesome. Cheers Rob

Hi Saasha, I have not done any stone carving, so I can't accurately answer your question. I have however used the HILDA to grind/cut away steel plate and it did it easily. The tungsten burrs I used were very aggressive (8mm) and easily did the job. You are only using light pressure and the grinder stayed cool. How it would handle stone dust long term is a bit of a worry, but the same issue would apply with an angle grinder. For any heavier/bigger diameter grinding you would need a more powerful unit. I hope this helps. Cheers Rob

Yes.

@@Xynudu Ok 🙂🙂

Top little unit Ronel. Very useful. Cheers Rob

I would have ordered one if it were available in 110V. I have not seen anything comparable (rated power, variable speed, chuck) at any price,

If you get it with one of these, it's still cheaper than a Dremel: smile.amazon.com/Simran-AC-500-Voltage-Converter-Transformer/dp/B004MPR3XQ/ref=sr_1_5?ie=UTF8&qid=1516934915&sr=8-5&keywords=120v%2Bto%2B240v%2Bconverter&th=1

Amazon sells a 120V unit that looks like the same thing. Look for MAXMAN

Try Amazon for a converter. They have several 2000 watt units. Be sure to get one that only has a transformer in it. Transformers run "backwards" i.e., 120 to 240, just as well as 240 to 120. You may have to do some wiring, but that should be straightforward. Then you can use the 400 W Hilda and any other 240 V device up to 2000 watts.

@@wjward8602 l cannot find this. I would be very interested. I have done a very long search to no avail.

I have a similar air tool which I used for many years before I got an electric die grinder. Air tools take much more punishment and won't overheat, so are favoured by industry. The downside is huge air consumption and noise. Both types of die grinders have their good and bad points and I use each as required. Cheers Rob

Hi Jorge, It's too hot to do much in the workshop at the moment, but it should be a pretty simple fabrication job, much the same design as for the pencil air die grinder. I will probably cut it out of heavy steel plate. I measured the alloy cylinder area at the chuck end (which I will clamp onto) and it was quite uniform for a casting - only 0.15 mm variation in diameter overall. So that's not too bad and better than an equivalent in plastic on a regular pistol grip drill. Years ago I did make a similar mount for a plastic bodied drill to allow cross drilling but there was so much flex in the plastic body that it was useless. I recycled the mount and deleted the video :) I did shoot a bit of footage sizing the current grinder to the lathe tool post to show how it would fit/work in, but didn't include it as the video was already quite long. Stay tuned. Cheers Rob

Hi John, The maximum diameter chuck it can takes is 30 mm. Anything larger will not fit into the recessed nose. 3/8" keyless are 40 mm and will not fit. 1/4" keyless seem to be sold with an Sds mount but that unscrews and if the thread is the same it would fit. It may however be difficult to grip as the chuck body will mostly be in the recessed rotary tool nose. Cheers Rob

Great work Rob, nice one mate

The Idea is fine, but running it at 25.000 rpm?

Nothing came loose. Should be OK.

Hi John, Very good point on the Dremel price. Cheers Rob

Hi Mick, I recon you could if you got the compact/micro chuck I've seen on some sites - provided the thread was compatible. Cheers Rob

No deflection in that chuck. Everything is tight and no visible runout. Rob

No problem 👍

Apparently the 110 volt version is only 280 watt. This is 240 volt version. I didn't check the wattage but it has plenty of power.

Where can l get a 120 volt one? I would pick up one if l could find one. I definitely want the chuck.

Hi Paul, you need that wrench to get the chuck off. It should be easy to make one from suitably thin metal sheet or bar. That's what I would do in your situation. Cheers Rob

Hi Bob, You can contact them and apply to be a reviewer. Here you go: forum.banggood.com/forum-topic-89845.html Good luck. Cheers Rob

I think the subscriber limit is flexible/discretionary as I don't have that many. Just apply and see what happens. Cheers Rob

Yes, it would handle that easily. There is an updated version with a machined mounting collar I reviewed recently which is a better unit: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jDDSWIQ7DEc.html Cheers Rob

@@Xynudu whoaa thankss!! excited to get this on my cnc.... my last Chinese 500w spindle had so much electrical noise and heated up so quick

Like a blender.

Same thing. They are both really die grinders with no gearbox - direct drive. So torque will always be lower than an electric drill, but they spin faster (armature speed) and are great for grinding, burrs etc. This one is quite a lot more powerful than a Dremel and can take various sized accessories as it has a chuck and isn't restricted to collet size(s) like most rotary tools. Cheers Rob

Hi Mick, Looks like I stuffed up on the price. Sorry for misleading you on that. I was wondering about that, as it showed the express post price but not the free post details. It seemed odd at the time. The Banggood site does weird things at times on prices. OH well, if it's no longer the bargain it looked to be, such is life. Cheers Rob

Thanks Rob. No problems. Wasn’t trying to blame you rather to correct the record. I still think it’s good value. Cheers Mick

I'm glad you pointed it out. Cheers Rob

As I am located in Australia I use Smith & Arrow 75 mm cutting discs (buy direct). This size (75 x 1 x 10 mm) are widely used by vehicle crash repair companies for panel trimming/removal and available from manufacturers and suppliers internationally under various brand names. Cheers Rob

@@Xynudu oh ok

Yes.

@@Xynudu Thanks

Apart from being much more powerful, it has the advantage of a keyed chuck, which allows much larger diameter mill bits, burrs and grind stone arbors to be fitted. Cheers Rob

@@Xynudu What about the bearings, are they more suitable? I honestly don't know what run out a Dremel has. But it is intended for some side pressure, when using some of the attachments. I could fit a keyed chuck to a Dremel with not too much work. Just don't know it its worth the trouble

I haven't had a Dremel apart, so I can't comment. As both units are primarily designed as die grinders, they will be able to handle significant side loads. The Hilda has a similar bearing size and setup to an electric drill. I expect runout to be very low on both units as per most die grinders. The Hilda will have much more torque than a Dremel due to the motor size.

Seems like 400 to me. Where did the 190 come from ?

I think they do.

Maybe someone from the USA can answer this. My understanding is that 110 and 220 volt are not interchangeable.

@@Xynudu No they are not. Does not work at all.

I've never tried. It might rev too fast. Cheers Rob

I have flap wheels that are 1/4 inch so it might fit

They should be OK. I was thinking you were going to use larger ones. Try it and see. Just watch the temperature doesn't rise too much. Cheers Rob

yeah would work but with half power...

Lots of countries in asia (which seems to be the target market for cheap powerful tools) use plug type A (USA) on 220v as standard.

It's as safe as any other electric drill. Lasting well. Yes it can use Dremel accessories. It runs off of single phase 220 volts AC.

@@Xynudu Did you have any problems?There is a newer Hilda in Banggood but with 450W you think it is better. I have seen this hilda tool in a russian channel and hesaid(from traslate) that this hilda you have might make smoke while drilling in high speeds.He said it can work on low speeds(

I only see the 400 watt Hilda being sold in Banggood. In fact I have one on order for my Brother in Law. It's currently on special for a short time. The unit does not drill really slow (so it's a bit fast for steel) as it is basically a high speed die grinder with a drill chuck. For wood this would be OK BUT at low speed you will lose power, that's how this variable speed works (it basically just reduces voltage). You could smoke the wood if you run it at higher speeds. I have drilled small diameter into wood with it without issue. The unit will only get hot if you run it slow with a big load on it. For grinding and cutting thin sheet metal with Dremel accessories it is fine and has way more power. I've never tried cutting wood with it, but it should be fine with small diameter blades/discs. The main thing is to not stall it or make it struggle. I mostly use 75 mm thin metal cutting discs in mine to cut bolts, rod, thin sheet steel. I use mine for Dremel type work and as a toolpost grinder on my metal lathe. It's a great unit for light loading work. Rob

I forgot to mention I have had zero problems with the unit and it is very well made with a good quality chuck (no run out or free play).

да.

Ha Ha I can't win. I guess it's a sign of the times. I guess I've been watching too many videos from youngsters lately and picking up their terminology. I could also be turning American as well ;) When I say something's awesome or cool I really do mean it, it's spontaneous, and I'm afraid that's something I use regularly these days - if it warrants it. What you see is what you get with this channel, and we all move with the times. Cheers Rob

xynudu I didn't want to say it that way 😂 too many watching and reading, cheers Derek
