The technical requirements of unpunched tungsten carbide cutting tools or that with a circular hole or counter bore are as follows:

I. The blade back flate’s inward concave should be not more than 0.05mm, while the outward concave not more than 0.03mm.

II. The blade’s fundamental plane only allows inward concave with value not more than 0.05mm in unpunched tools or tools with a circular hole, while allows outward concave with a value not more than 0.03mm in tools with a counter bore.

III. There should not be any defects unfavorable to usage on tungsten carbide indexable insert surface as well as defects in the cutting edge part.

IV. The main properties and structure of blades should accord with the regulations in YB849-75 Tungsten Carbide Grades or other relevant standards.

V. The cross-section part of blades should be in uniformity without any defects that may do harm to usage.

VI. Materials newly developed or introduced should be of higher properties than what stipulated in YB849-75 standards or accord with companies recommended values.
