Description
The OSG Threading Tap is a metric A‑Spiral Flute Form E tap designed for blind‑hole threading. Built for machinists and job shops that demand dependable, precise threads in metal, it delivers extended flute length and advanced coatings to boost performance in challenging tapping operations.
- Threading Tap Type: Metric A‑Spiral Flute, Form E for deeper blind holes and efficient chip evacuation
- Material & Coating: Powder metal substrate with TiCN coating for enhanced hardness and wear resistance
- Size & Thread: M8 x 1.25 with DIN 376 specification alignment for metric threads
- Handedness: Right‑hand thread, optimized for standard blind‑hole tapping sequences
- Chip Evacuation: Spiral flute design improves chip removal, reducing tap binding and breakage risk
- Application: Suited for demanding, high‑speed tapping in blind holes across ferrous and nonferrous metals
- Durability: TiCN coating and powder metal construction extend tool life in repetitive production cycles
This tap targets professionals who need consistent thread quality in blind holes without frequent tool changes. The extended flute length (Form E) supports deeper tapping depths, while the TiCN coating lowers friction and enables higher cutting speeds. The result is fewer interruptions, steadier finishes, and longer tool life—especially in production environments where reliability matters most.
