I use it attached to an electric drill.
Do not forget to add drilling oil and use it for long lasting.

There is no problem. In addition, I will purchase it if necessary.
Tapped hole of control board inner plate
On 2017-02-28 11:13:50
I used OSG, but this tap is not usable because it can break easily as it is caught. I should worry about pilot holes from 3.3 to 3.4, but I am worried because there is only 1.6 steel plate. I bought some but the others were the same. In the case of OSG, there is no such thing.

During small-diameter screw standing work, I often taste the tears of tap breaking. For inexperienced metalworking, the low price of this product is the salvation at least.
When tapping products
On 2015-04-23 14:58:15
Although it seems to be somewhat impossible to cut, price is a little cheap, so well, COSPA is subtle.
With set refill!

I broke up during work the other day and got it by supplement.
Tap cutting of woodworking

For this size, if it is hard wood, you can make a firm tap with wood. You can save the ogre if it is an application that does not require drawing power.
Drilling tap work

Tap work can be done normally. Although it is a consumable item, we will decide on durability from now.
Tap of steel material.
On 2013-12-04 14:03:13
It is good for SS and SK material, but there are some durability when it is hard material such as SKD, DC 53 etc. Because other taps are so, I will only do this review.
Plain penetration tap up to t12 mm
On 2013-10-28 09:41:56
With a radial board, I think that it is very good if it is up to 12 mm with plain board, I broke it if it was t25, I use it properly.
General steel thread cutting

The cut is good. Do you own it normally?

To be able to break
Tap processing in machining, then for hand
On 2013-03-25 18:09:04
Although it is not inferior to other manufacturer's products in the usual use range, it is slightly shorter feeling, so change it before breaking and use it in hand.
SK material use
On 2013-03-11 16:42:56
It is usable as usual. I have not tried hard materials yet.
Used for SPHC 3.2 mm. . .
On 2013-02-20 13:25:31
From the first place of the first piece suddenly breaks. I used three new items, but I also broke up so we made it in time with worn-out other companies' products. Worn-out sharpness is getting worse but never broke. As I saw the review I felt like a thin sheet so I thought I was going to buy it, just happened to be?
Screw hole production
On 2012-08-27 18:31:50
I used it for the φ 65 welding long elbow with the bottom hole φ 6.8, but the tip was broken at the second hole and the eye was a point (> _ <)
Tapping work such as shape steel
On 2012-01-21 09:55:25
I used it continuously because the price is cheap, but I feel like quality has recently deteriorated. Even if you use a tapping spray, it can be broken with the first use when it is no good. Rather than forcibly loading and breaking, it is like "breaking". From the cost point of view, I would like to use it if the quality improvement is made, but if it keeps it, the Yamawa product ultimately outperforms the cost.

It is used for a thin plate (1.6 to 6 ㍉).
On 2011-11-16 20:55:09
Since I have not bought it, I can use it normally for my present place.

Sharpness is also good, I use it without problems.
