Processing of laboratory instruments

It is very convenient that a step drill becomes a set for a straight drill. The price is reasonable and very useful. I thought that I wanted it for individuals not for work, but it is regrettable that handling is over. I confirmed the substitute, but I am a bit disappointed with a set of straight drills.
For drilling work
On 2017-11-28 22:06:03
It is still unused, but it was cheap so I think I can get original just by being able to use it once or twice.

3 mm or less is not usable. It broke soon.
Even though titanium coating is applied, I think it is a matter of the material before that.
I do not use it because I do not use 3 mm or more.
As a result, I used a regular steel drill.
For professional use it is not usable, it is for amateur DYI to the last.
Especially, it is not suitable for torquey impact and drill driver.
Mainly for drilling of wood

As of now I can use it normally. It is relatively inexpensive, has step bits, it is useful.
For metal processing

Purchased for metalworking finish. Especially the step bit is a hexagonal axis, it is easy to detach and increase work efficiency. It is useful for deburring of the cut surface.
During machine operation

I think that performance is sufficient for price. It is a compact, portable, good price and it does not hesitate to buy again even if it breaks.
Drill holes for tapping iron

It was good to use it well. I am using it for punching holes in tap pins.
When creating the test tool

Even though each size is aligned, Takeko naka is still a big success!
When preparing pilot holes such as rafters
On 2016-12-27 09:43:50
Used by attaching to the impact driver. The axis of the center is slightly misaligned. While pushing it will shake it.

It is good that the step bit is set.
On 2016-04-07 14:42:01
I do not know because it is only used a little yet, but I think reasonably well.
Drilling of aluminum and wood
On 2016-02-25 22:39:54
As others have said, almost all diameters do not come out of the center and almost all axes are crazy and tilted, so it can not be used properly because it is shaken by Brunmble. If you do not use it well by suppressing vibration, it breaks. Those with small diameters will break easily unless they are careful. The size is almost aligned at this price and the thick diameter is especially useful because the step drill is particularly useful ★ I made it two.
It is used for maintenance, processing, disassembly of machinery.

I bought it as my 2nd in my precious autumn work. It is convenient because it is affordable and easy to use.
On 2015-05-07 17:23:49
The hexagonal axis, the center of the drill is not out. Result The drill broke.

The price is also worth the price, goods can be used so much.
On 2015-03-09 09:42:29
It is cheap I do not know yet other things yet I do not know why I buy anything, so I think it is good to frequently buy cheap things
Drilling work in the workplace
On 2015-01-19 23:11:01
It is convenient because it can be used in addition to the chuck, but because the hexagonal part and the center of the drill are not out, I will buzz. If it is a thin article it will manage somehow, but I think that making a little is poor. Is it price suitable?
Drilling in aluminum material
On 2014-09-29 17:46:18
The center did not appear and the drill broke. I am in trouble if the center does not come out even on the hexagonal axis.
With the processing of the screw hole of the screw!
On 2014-08-27 11:29:31
When setting in the drill, 1.5 mm of drill opens 2 mm with core shake, it is disappointing for accuracy to fully swing when trying to rotate it all.
Drilling of wood before screwing
On 2014-08-04 09:17:03
When I used it for the first time, I clearly understood the difference from the past one. I could open a hole without blurring easily without putting force on metal. I am looking forward to how long it will last.
