Werka DIN40430 HSS PG Thread Straight Flute Machine Taps

Taps cut internal threads. The standard (DIN371, 376, 374, 2181, 352, 5156 ...) sets the shank and length, the thread type (metric, fine, UNC, UNF, BSP, NPT, PG) the profile. A straight flute tap is for through holes and short-chipping material, a 35° spiral flute tap for blind holes because it lifts the chip out; a forming tap shapes the thread without cutting chips. HSS-E, cobalt steel and TiN and TiCN coatings extend life in difficult material. This family comes in 4 options: 9mm x PG7/70x20, 12mm x PG9/70x20, 14mm x PG11/80x22, 16mm x PG13.5/80x22. The order code of each is in the specification table; quote the code when you ask for a price.
