What is a precision notation STD?
Accuracy notation STD is the accuracy of the tap recommended when machining thread accuracy grade 2 or 6H female thread equivalent. The accuracy notation STD indicates how much tolerance the effective diameter of the tap is controlled. It is an abbreviation for Standard. STD+1, STD+2, etc. are called oversizes.

The cone-shaped part of the tap tip is called " external center ".
This part is attached during the manufacture of taps and is not used during threading.
The presence or absence of external center is determined by the type of tap and the range of size .

The shank diameter of the tap is conventionally determined by JIS, etc., but it is generally used in end mills when used in machines with a full lead feed function.
By using diameters such as 4 mm, 6 mm, and 8 mm, it is a shank shape that can enable a strong and precise grasp.

The rotational resistance in tapping is called the cutting torque of the tap.
Factors affecting torque are related to the shape of the tap, such as the type of tap, the size of the angle, and the length of the bite.
There are cutting conditions such as the type of workpiece material, threading length, and pilot hole diameter.
These are int

The following points should be paid special attention to when tapping.
(1) Tap selection
Check whether you are using a tap that is suitable for the type and hardness of the material from the list of suitable materials in the catalog. Depending on the through hole or bli

Cutting data of tapered taps for pipes Calculation method PT (Rc)
The following formula is used to calculate the cutting data in the same way as for metric screws.
Rotation speed (S) = (cutting speed ×1000) ÷ Tool diameter ÷ Pi (3.14)
Feed speed (F) = pitch × rotational speed
