Product Description

YG-1 TB313 is a metric spiral flute machine tap with special flute geometry for blind holes. Designed for ISO metric coarse threads to DIN 13, it evacuates chips efficiently from restricted holes. Its HSS-E material and Vap finish support tapping in the listed recommended materials. The series is rated excellent for high-alloy and tool steels, and good for hardened steel.

DIN 371 and DIN 376 forms cover the supplied M3 × 0.5 through M16 × 2.0 variants. A C 6H tolerance and 60° thread angle suit specified ISO metric coarse threads. The spiral flute moves chips away from the cutting zone below threaded depth.

  • Special flute geometry supports blind-hole tapping and chip evacuation
  • HSS-E metric coarse-thread machine tap
  • Vap finish with R40 geometry
  • Excellent recommendation for high-alloy and tool steels
  • Good recommendation for hardened steel
  • DIN 371 and DIN 376 forms with C 6H tolerance
