The OSG Threading Tap in Metric A‑Spiral Flute is crafted for precision threading of metric blind holes. Designed for engineers and machinists who need dependable, consistent results, it combines a TiCN‑coated finish with a stable HB Weldon powder-metal shank for demanding tapping tasks.

• Threading Type: Metric A‑Spiral Flute optimized for efficient chip evacuation and smooth cutting in blind holes.
• Material & Shank: Powder‑metal HB Weldon shank delivers rigidity, alignment, and reliability during high‑precision tapping.
• Coating: TiCN (Titanium Carbo‑Nitride) coating provides a harder surface with lower friction to extend tool life.
• Size & Standard: M4 x 0.7 thread, compatible with DIN371/1835 blind‑hole applications.
• Grip & Geometry: Right‑hand thread for standard metric tapping with stable engagement.

In practical use, this tap helps you produce clean, accurate threads in blind holes with reduced clogging and wear. The spiral flute design enhances chip removal, lowering the risk of chip packing that can affect thread quality. The TiCN coating together with the durable powder‑metal substrate supports longer tool life under recurring production workloads, while the HB Weldon shank maintains precise alignment and steady cutting stability.
