Correct against sides of the drill bit (angle), but I think that may be simple if you can
My blade edged is not expired yet.
Drill bit playback and modification

But I was puzzled a little bit because the method of use has not been specified in detail, easy to handle because the angle is uniformly easy to align
Re-polishing of household drill

The first table position adjustment that it from the (groove side) did not look good, but parallel when viewed from the back side was able to easily successfully re-polishing out.
If there is a pressing by the spring or the like so that the drill is not float when you're easier to use more. I am wearing a sponge rubber to the horizontal bar.
φ5 challenged the cutting edge polishing of the drill, but not understand, did not work.

It is polished only the portion of the cutting edge shape "to", or would have meaning. Conversely, it would be trimmed off and sharp parts of the tip, is the sharpness becomes worse? I can not quite understand. If there is a practical experience, and we'd appreciate it if you could tell me. After the purchase, but also challenged many times, it is playing in the state that can not be used yet.

Situ, was purchased I think whether there is a practical became blade can sharpen rather sharp. Decent Togeru of or worry because it does not use yet.
Work of a drill to sharpen
On 2012-03-15 19:36:27
It can not be used, because is he who called.
First, look at the cutting edge of the drill tip is somewhere in the magnifying glass, the same mark with a pen in around the axis of somewhere drill is a place to be at right angles.
Cutting edge left and right (?), So there should be two places, also marked another place.
Set the drill into the groove of this product.
At that time, with the mark will be set to come on.
After lightly pressing the drill to the grinding wheel (it may even better looking at the contact condition of the grinding wheel and the cutting edge with a magnifying glass), "Turn the grinding wheel with a finger." (Electric tool to sharpen the knife should not be required)
Once sharpening a little, neatly cutting edge it might be better to check whether it has been grinding.
If you did not seem cutting edge thorns, it will be good and I'll slightly tilted position of the mark.
And polishing both the right and left (?) In such a feeling.
In some cases, prior to polishing, it may be better and I'll be thinning processing.
I was doing the thinning processing mock by watching someone's example a drill of 2mm in the triangle of the diamond file, biting is now well.
It should be noted that, because we have used in the drill holes work on a printed circuit board (Bakelite plate) with a drill of Φ0.5mm ~ 2mm, whether above or enough when holes in the iron and aluminum is to do not know, take the center you might trouble even some of that occurring in the not, but it does not know the neighborhood.
But, obviously improvement was seen.
Those that middle. Was not shaved, now out shaving Kasuga Hluhluwe just turned with a finger.
If I, will make things move in the mainspring. I think that it will further slow down the rotation speed by the gear.
Electric drill You too large, such power is not required.
I do not know whether when it comes around to Φ12mm, but, kitchen knife is not Togeru manually but there is a range of more blade.
If If the put the rotary tool, it will side of the drill.
Or the grinding wheel will not too soft. Grinding wheel will deform immediately.
The fact that the eyes of the fine electrodeposition diamond is good?
Even if to do with the grinding wheel, Nari to those hard the substrate Nari reduce the ratio of the bubble, I feel like there is something.
But was turning the grinding wheel with a finger, the advantage is there one, but the grinding wheel will move somewhat in the direction of the root from the previous, to take advantage of it, is to move somewhat with your fingers so that it does not cut in one place of the grinding wheel .
To the axis of the grinding wheel to the screw, and us moving the contact surface of the grinding wheel while you are turning I think better.
Polishing of the drill bit

I tried with trying to polish a drill that has become a little bit of sharpness bad, it has become a drill that does not cut far from subtle.
It is what I want you to tell me if there is a good use.
Tip polishing of alone with iron and steel

It does not have what way to use. There is no find use in much want you to a refund. If there are those that can be used very well, I would like to tour the work.

PS. It was also necessary to get the hang several attempts to Togeru well to. A drill to fix, to stabilize the rotation at low speed, has been practicing against the way of the blade.

But not good evaluation of other people, since they are expensive, tried dare. Sharpness of very drill bit has improved. You have towards the re-trial.
