Hello, everyone.
This is Enta.
This hammer drill I bought a while back
Rechargeable and standard 100V.
I was somewhat prepared for the fact that it's rechargeable, so it's not a problem.
Buuuut!
Hi-Koki DH40SE
List Price: 82,400 yen
Online Price: Around 51,000 to 60,000 yen
I bought three of them!
Let me be clear:Don't buy it!
You must not buy this model!
The reason is,It cannot be used in the mountains.
I think the slope contractor will install the main anchors at the intersections of the slope frames.
If there are pebbles or gravel in here, it will stop spinning easily.
I hear that recent models are brushless and come with overheating protection, but I guess this is where they fall short.
Anyway, it gets super hot and then stops.
And on top of that, it’s not like I’m drilling that much!!
Also, the hammer drill gets stuck in the middle of drilling, so I can't pull the drill bit out.
Either remove the hammer drill and pry it loose with a monkey wrench, or
Should I set up that old Hitachi hammer drill again and give it a try?
I'm just like, "What is this?"
What's more, suspecting a manufacturing defect, I sent all three units in for inspection and repair.
The hammer drill that came back stops just as easily as before.
To put it bluntly, this is a model you shouldn't buyThat's it.
Since it seems the older hammer drills are no longer in production, I bought a Makita hammer drill (HR3811).
This Makita tool can drill holes just fine, so there was no problem.
It's fine for drilling holes in concrete, but it's not suitable for slope stabilization work.
Please be careful, everyone.
We've already bought three Hi-Koki DH40SE units... orz
If I were to buy one right now, would Makita be the best choice under the current circumstances?
See you later.
