Emkay manufactures spiral fluted taps in 15° to various standards like ISO, DIN, etc.
These taps are suitable for blind hole applications for steel of tensile strength 1000 upto 1300 N/mm2.  

Further, we can also make these taps in Powder Metallurgy grade, which can work on steel of tensile strength 1300 upto 1600 N/mm2, such as spring steel, hardened wear resistant steel, maraging steel, etc.  These taps can also work on chilled cast iron 400-600HB and titanium, commercially pure, and titanium alloys above 730 N/mm2.  

We can also provide special geometry 15° spiral fluted taps suitable for making various cast iron components.
