The OSG Threading Tap is a precision metric fine thread tap designed for cutting threads in blind holes with clean, accurate results. Built for professional workshops and production environments, it combines a rugged powder-metal body with a TiCN coating to deliver reliable performance in demanding internal threading tasks.

• Thread Type & Size: Metric fine thread, M4 x 0.35, right-hand orientation for blind-hole applications.
• Flute Design: A-Spiral flute configuration that promotes efficient chip evacuation and reduces clogging in deep blind holes.
• Material: Powder-metal substrate offering enhanced hardness and wear resistance for longer tool life.
• Coating: TiCN (Titanium Carbo-Nitride) coating to lower friction, boost hardness, and sustain performance at higher speeds and temperatures.
• DIN Standard: DIN 371 compliance ensures reliable interchangeability and consistent results across tooling setups.
• Applications: Ideal for precision internal threading in small-diameter blind holes across manufacturing, repair, and assembly environments.

Designed to deliver consistent, accurate threads in constrained spaces, this tap minimizes resistance and chatter while maximizing tool life. The TiCN coating and powder-metal construction work together to endure repetitive cutting, making it a dependable choice for fine-thread needs. Its spiral flute design aids continuous chip removal, helping you achieve clean bottom-threads in blind holes and reducing downtime due to rework or tool wear.
