I think that it is easy if the drill blade's proper way of applying (angle) can be done, but my sharpened blade can not be cut yet.

I was a bit puzzled because the usage method was not described in detail, but it is easy to handle because angles are uniformly and easily aligned

Although I could not see the position adjustment well from the first table (groove side), it was easy to put out parallels as seen from the back side, and it was able to re-polish well. It will be easier to use if there are holders such as springs to prevent the drill from floating. I have sponge rubber on the side bar.

I challenged the cutting edge of φ5 drill, but I could not understand and could not use it.

Even if you grind only the part of the edge shape "ha", is it meaningful? On the contrary, the sharp part of the tip is scraped off, and the sharpness becomes worse? I can not understand it at all. If you have practical experience, it will be appreciated if you can tell me. Although I tried many times after purchase, I am playing in a state that I can not use yet.

I purchased it because I thought that there was practicality because I could sharpen the cutting edge which I could not cut at the work site. Since I have not used it yet I am worried about whether it can be done properly.

ドリルをシャープにする作業

使えない、という方がおられるので。 まず、ルーペでドリル先端の刃先がどこかを見て、それと直角になるところがどこかドリルの軸の辺りにペンで印を付けます。 刃先は左右(?)二箇所あるはずですので、もう一箇所も印を付けます。 この商品の溝にドリルをセットします。 その際、付けた印が上に来るようにセットします。 ドリルを砥石に軽く押し当てたら(ルーペで砥石と刃先の接触具合を見ると更に良いかもしれません)、「指で砥石を回します」。(包丁を研ぐのに電動工具は必須ではないはずです) 少し研いだら、ちゃんと刃先が研削されているかどうか確認した方が良いかもしれません。 刃先が研げていないようでしたら、印の位置を少し傾けてやると良いのでしょう。 そんな感じで左右(?)とも研磨します。 場合によっては、研磨する前に、シンニング加工してやるともっと良いかもしれません。 私は2mmのドリルを三角のダイヤモンドヤスリで見よう見まねでシンニング加工もどきをしてやったところ、食い付きが良くなりました。 なお、Φ0.5mm~2mmのドリルでプリント基板(ベークライト板)に穴を開ける作業で使いましたので、鉄やアルミに穴を開けるときに上記で十分かどうかは判りませんし、センターが取れずに不具合が生じることもあるのかもしれませんが、その辺りは判りません。 ただ、明らかに改善が見られました。 中々削れなかった物が、指で回しただけで削りかすがシュルシュル出るようになりました。 私なら、ゼンマイで動くような物を作るでしょう。更にギヤで回転速度を落とすだろうと思います。 電動ドリルは大きすぎますし、そんなパワーは不要です。 Φ12mmくらいになるとどうか判りませんが、しかし、包丁はもっと刃の幅があるのに手動で研げるわけです。 もしも回転工具を付けるのであれば、それはドリルの側でしょう。 砥石は柔らかすぎないでしょうか。すぐに砥石が変形します。 目の細かい電着ダイヤが良いということは? 砥石でやるにしても、気泡の比率を抑えるなり基材を固い物にするなり、何かあるような気がします。 指で砥石を回しましたが、利点が一つあって、砥石が先から根本の方向にいくらか動きますが、それを利用して、砥石の一箇所で削らないように指でいくらか動かせることです。 砥石の軸をネジにして、回しているうちに砥石の接触面が動いてくれるともっと良いと思います。

I tried to polish a drill that was a bit sharp, but it turned out to be a drill that could not be cut down. I would like you to tell me if there is a good way to use it.

There is no use for anything. There is no use as much as you want refund. If there are people who can use it well, I would like to see the work.

Postscript. I had to try and grab the hammer many times to successfully sharpen it. I fixed the drill, stabilized the rotation at low speed, and practiced how to apply the blade.

Evaluation of others is not good, but it is not expensive, so I dare tried it. The sharpness of the drill blade improved greatly. If you have a retry.
