Yamawa Carbide hand tap for high hardness steel EH-CT P4 M12X1.75 5P

[Features]
●Ideal for tapping high hardness steel of 45 to 55HRC such as steel for hot working molds (SKS3, SKD11, etc.).
● Uses ultra-fine cemented carbide with excellent wear resistance and impact resistance.
●The run-out accuracy of the entire tap and the roundness of the shank have been improved.
●Thread processing length is set to "outer diameter x 1.5 or less", and chamfer is 5P in consideration of service life.
●We recommend the maximum inner diameter of 6H female thread for the pilot hole diameter.

[Use]
●Work material: For tempered steel (45 to 55HRC).
