The OSG Threading Tap, Metric A-Spiral Flute Form E, is a right-hand, TiCN-coated tool built for reliable blind-hole threading. Designed for machinists who need depth, durability, and precision in metalworking, it delivers consistent threads in deep pockets.

• Material: Powder metal construction for high strength and wear resistance.
• Coating: TiCN coating to increase hardness, reduce friction, and extend tool life.
• Flute design: A-Spiral Flute with Form E provides an extended flute length for deeper blind holes and efficient chip evacuation.
• Thread type: Metric threading with right-hand orientation, compatible with DIN371 blind-hole standards.
• Size: M3.5 x 0.6 thread and size specification.
• Application: Optimized for tapping blind holes where depth and chip control are critical.

Benefits: This tap delivers clean, accurate threads in challenging blind-hole work. The spiral flute design enhances chip removal, reducing the risk of tap breakage and downtime. The extended Form E flute length enables deeper tapping without frequent tool withdrawal, while the TiCN coating sustains performance under high-speed, demanding operations—helping you complete precision tasks faster and with tighter tolerances.
