I wanted the eyes to be a little more detailed, but I did not understand the details.

Drill polishing

Since cracked items arrived, we had them replaced. Although excess packaging is unnecessary, things that are easy to crack wish suitable packaging. Product can be used without problems. I feel that the grinding power is stronger than the orange grindstone.

Drill bit polishing # 80 used for most finishing
From Japan
On 2017-02-06 20:06:54
I thought that there was considerable hardness by using a general purpose bit (binder), but I could easily correct the surface by diamond brick dressing. However, although it is hope for Monotarou future, there were a few scratches that seems to hit while the whetstone and diamond bricks are being transported. There was no problem level because it was dressing. I will tell you that this kind of hand in the packing box needs to be devised not to move.

Drill sharpening
From Japan

I use it for drill polishing and thinning of about φ1 ~ φ3 with a grain size 220, 150 x 6.4 x 12.7 and a thin and thin grinding stone. It was difficult to use and easy to use stone when thinning was reduced.

Finish grinding of high sprayer
From Japan

It has hardness and can be polished cleanly. A WA GC think that it will improve usability if you arrange it.

Polishing of working blades
From Japan
On 2015-01-14 18:37:41
(3 points closer to 19800 yen) I bought a desktop bench grinder GD-200 + diamond dresser set and purchased additional because the roughness of the grinding stone did not match the intended use. It has become possible to polish very well using it by lowering the rotation speed of the grinder.

Made in China Mounting on the main body, polishing of dust etc.
From Japan
On 2011-03-25 21:21:54
I used it attached to a cheap Chinese made body, the grinding stone attached at the beginning was eccentric or the vibration was intense, but it changed to kore and it became no vibration. It is very easy to use. I think that it is better to use good ones even if the main body is a cheap article made in China.
