Review Onevan DHP458 Clone

[Memmeddu]

Hi everyone between yesterday and today I've got the time to disassemble reassemble and test the Onevan "650Nm" comby drill.
Let's start saying it surely doesn't have 650Nm or 140Nm advertised on Amazon.
Still have enough power to complete every hobby job we might need.

Here we have it in all its chinesium pride.
Overall a nice drill for the price paid just 60 euro but you can apparently get it for a lot less on Chinese websites like AliExpress Banggood and Company.
It's a mixed designs product, I call it DHP458 clone because it resembles a lot Makita products, it uses LXT batteries, and because it's the model number to which it gets closer while speaking about performances.

It came in a not great but not bad either hard plastic carrying case.
There are two 3Ah batteries, fireproof charger, side handle and a little keychain.

The handle looks inspired by Milwaukee both for shape and locking mechanism, cheap and sturdy enough to withstand the torque delivered by this drill.
I'd like if they implement a little spring to spread the detents apart when loosening it, but we are already lucky they used a little guide rod to keep them aligned

Brushless written on a side of the Battery well

XGT logo on the other.
They may have thought that LXT was too old and so the logo the most recent battery platform offered by Makita has to convince more customers to buy it.
Great

Anyways that's how it looks inside.
Nothing special, we don't have the regular clone PCB we are used to find on impacts

We have battery and power indicators but not a selector button.
Which can be implemented theorycally because the panel has the button

The stator windings are so far the best I've seen on clones yet.
Thick windings, epoxy in place, nothing comparable to real Makita but at least some sort of quality.

The rotor has a very strong magnet, nice and robust cooling fan, it's yellow too
Anyways it spins on two 625-2RS shielded bearings which is nice to see

Are these clones any good?

When I was on the tools, buying proper stuff was the only answer, but now I drive a desk I'm tempted by the clones

We a three stages planetary gear reduction with a bypass gear to essentially transform it into a 2 stages one, increasing the speed (second gear)
Nothing special if not for the first stage gears that runs on little needle bearings
And honestly I've never ever seen something similar

Here we come to the nicely machined aluminum housing which almost made me give up with this thing.

6 clutch poles, 3 pin spindle locking mechanism.
Held together by four little M3 screw made out of cheese and an huge amount of high strength Loctite.
Broken one of those screws in the upper right.
After attempting everything to remove it I've ended up drilling it, got sideways, drilled a good 70% of it, hammered with a chisel nothing to do it's still there.
Cut new threads on the housing and what remains of the screws.
I'm extremely curious to know what type of thread locker they used because it's extremely good stuff, it didn't melt with fire and didn't give up under the hammer.
Reassembled using new screws

Very impressed with the chuck.
Which initially didn't TBH.
But ended up to be a "nice" fully serviceable, auto locking, keyless chuck

I didn't check the thread pitch, it should be regular 1/2" 20 UNF but looks metric to me.
The only bad thing about this chuck are those big openings in the bottom that I can bet will let a lot of dust and debris to go inside

Tested with a torque wrench, the drill managed to make it clicks up to 60ish Nm but I can be more.
Electronics cut off the power at this point.
I've then driven an 8x200mm screw halfway into a piece of hardwood.
The motor slowed down a lot but it didn't stop.
The screw got bent and I have not been able to remove it even using the breaker bar.
So I think it has enough power and torque for hobby use.
Surely enough to drill larger diameter holes.
It does have hammer drill mode, drill mode (no clutch) and driver mode (clutch).
More testing required but overall worth the price

You get what you pay, but I've been overall enough lucky with mines.
I've decided to take a part and review them on the forum because there's not much on internet about clones , and you don't find opinions about the internals and usually who test them are paid or complete incompetents.
I'm trying to share what I see and feel, and how they work for my needs

Good review.

I have been using my Onevan drill today, it has a diferent, plastic chuck which is not great. However it has lots of torque with a 10mm drill bit in steel and wood, cant complain for £20.

Also been using the grinder, it has a noticably slow RPM speed but cuts quite well and the included discs havent exploded yet.

I have the DGA504Z clone, almost exact copy of the the real one, plenty of torque and normal RPM, variable speed on 3 preset levels.
Very happy with it too, didn't reviewed it yet because I'm kinda thinking about getting other 2, one from Gisam that till now by experience with my clones offers the higher value for the price.
And the KATSU DGA513JZ clone with continuously variable speed.
One of the Three will be used as belt file or polisher, I might even get one review it and send it back just for comparison but I can throw 30 euro on it no problems.
The only thing I've noticed a part the fact they are sold with a bone dry gearbox is that they are extremely power hungry
