Yamawa NRZ-G8 M12x1.75 (NRZM8012PP) Steel Roll Forming Tap (Made in Japan):
- Chipless Cold-Forming Technology: Generates internal threads by plastically deforming material fibers without cutting chips, eliminating chip clogging and tool breakage.
- Superior Thread Strength & Mirror Finish: Cold-working increases thread surface tensile strength and fatigue resistance with smooth burnished thread flanks.
- Solid Core with Oxide Treatment: Thick core cross-section resists torsional fracture; black oxide (OX) coating prevents metal welding and galling on medium carbon steels.
- 4P Chamfer for Through Holes: 4-pitch guide chamfer (PP suffix) provides optimal progressive entry for stable through-hole threading on CNC machining centers.
- Applications: Automotive engine chassis threading, S20C/S45C carbon steel machining, and precision metal fabrication.
