RKAH – shaped tap is ideal for grinding, short cutting materials, such as cast iron or hardened steel, in which the flute can only hold a portion of the chip. There is almost no chip transfer in the axial direction. We do not recommend the use of this faucet in a deep blind hole, nor do we recommend long hole threads.
features
Rigid groove design
PD application hard coating is available
Chamfering C(2-3 threads)
Chamfering E(1.5-2 line)
Blind and bore threads
3 d standard options: DIN/DIN, DIN/ANSI or ANSI/ANSI
benefit
High tensile strength material
The relatively high relief Angle of the surface treatment or hard surface coating ensures the long service life of the frosted material.
Cast iron -CDGI/ADDI material with vermicular cast iron
The newly developed automobile industry casting material often shows very special grain structure with low weight and strength. This high-intensity weight is a trade in tool life. CDGI (compacted graphite iron) and ADDI (Austin’s nodular cast iron) materials are also very challenging for machines, and tool life is a problem. The faucet of the em-g joint venture employs a number of flutes and a specially adapted geometric figure. The powder metal’s high-speed PM tool allows for longer tool life, even in these highly worn materials and ordinary cast iron.

Blind and bore threads
RK a-hcut has a geometric shape, a special adjustable flute profile, and a special Angle of inclination and relief Angle for thread cutting in hardened steel applications. Metal powder manufacturing, (HSPSM) cobalt high speed steel or submicrocrystalline hard alloy substrate material. The EK A-HCUT powder metal HSPSM tool is suitable for hardness of 44-55 HDRC materials. Hard alloy RK A-HCUT tools have a hardness of 535-63 HDRC.
