It was used after the purchase, but it was broken immediately. It must be a little more durable.

Why? Satisfaction is bad, because the center axis of the center axis of the drill bit of the hexagonal axis is displaced.
We asked the manufacturer, up to a maximum error 0.2mm is seems acceptable range.
Impact drivers that are generally sold, center axis deviation to the minute to handy processing the drill, the deflection at the time of play and the handy work of the mounting portion of the hexagonal axis, drilling size is large because the hand (arm) is absorbed now is hard, but when you work in a machine such as a milling machine, drilling machine, lathe is up to 0.3mm greater than drilling the desired size.
Cause is because of the center deviation of the hexagonal axis.
I am a straight short drill scraped off all the hexagonal shaft on a lathe.
Deflection of the drill after scraping off all the hexagonal axis is roughly 0.05mm or less.
Even in ordinary hexagonal axis products, because with a hexagonal axis in retrofitted to an ordinary straight drill, error (deflection) seems to become really big.
Straight drill and rather than make the hexagonal axis to separate, who was made to collectively is I asked the manufacturer and do not the error (deflection) is small, so the manufacturing cost is several times.
Then, yes it increases five times closer than the straight drill.
Purpose (customer base) is used in impact drivers that are generally sold in for people who are used to create a beginner or DIY, is not a professional.
However, it will be marked with each size of the drill chuck to the impact driver, because it is after all the hexagonal axis mounting type of drill chuck, swing error is so up to 0.5mm hole becomes larger.
(Depending on the drill bit diameter and the drill chuck grasp possible size.)
If you want to use in a machine such as a milling machine, drilling machine, lathe, let's use a straight-through drill.
Or, the hexagonal axis drill to understand towards the drill bit on a lathe, let's cut the hexagonal shaft portion to the shaft system of Φ4.0mm.
In the case of drill you want minimum grasp diameter of the lathe and drill chuck is processed, when the lathe is available for processing 3-jaw chuck (fingernails) separately, let's processing.
In the case of milling machines and drilling machines, let's create a dedicated collet chuck.

Unused, but looks good.
Tip should vacant hole in the punch street because shape as center drill?
Since the bit and drill I think whether solder because there is strength is the anxiety, but is the price is the price.
Titanium coating it has reduced ☆ one because it is hate.

Because of the short drill, it was easy to use without any drill break worry
It should be noted that good or if there is a large set of
Use, such as the pilot hole of the plate

You break well long drill but, short of seems hard to break.

Very easy to use. Work that it is short easy to force enters efficiency UP!

Compared with the general drill, bite of the blade is opened as early hole in a well-light mosquito.
Drilling to the iron angle, etc.

Since the long and fragile absolutely those of small diameter
This time I bought this short a minute.
Now I hope to us to long-lasting even a little. (Lol)

Drill for impact drivers that are generally sold is long there are many.
There was a case of difficult to use too long in some places to use.
Here has expired well and easy to use Short.
If it is about DIY is here in plenty.
Blurring of the center it does not matter if you use a center punch.
