Crafted for automotive, aerospace, and engineering applications, these E398 taps are perfect for threading blind holes with high precision. Made from high-speed steel with powder metallurgy (HSS-E-PM) and coated with TiCN, each tap offers excellent wear resistance and durability while the spiral flute design ensures efficient chip evacuation, preventing clogging.
Features and Benefits
Versatile geometry prevents clamping in medium to high strength materials and avoids oversized threads in soft materials
Modified edge treatment and rounding increases cutting edge stability and reduces the risk of edge chipping
3-radii flute profile provides maximum control of cutting properties and ensures proper swarf control
TiCN coating offers high wear resistance with a low coefficient of friction
