The OSG Threading Tap is a precision tool designed for metric fine threading in blind holes. Built for high-speed, high-accuracy tapping, this right-hand tap uses FORM E geometry and advanced materials to deliver clean, reliable threads in challenging blind-hole applications.

• Size / Pitch: M4 x 0.5 (DIN371 standard)
• Flute Design: A-Spiral flute for effective chip evacuation and smooth cutting
• Geometry: FORM E geometry to produce consistent thread profiles
• Material: Powder-metal body for enhanced wear resistance and durability
• Coating: TiCN coating increases hardness and reduces friction for longer tool life
• Orientation: Right-hand tap optimized for metric threads in blind-hole tapping

Designed to tackle the demands of precise blind-hole threading, this tap combines robust construction with anti-friction performance to deliver consistently accurate threads, reduced tool wear, and efficient chip management. The TiCN coating and powder-metal substrate work together to extend cutting life, while the A-Spiral flute helps prevent chip buildup and maintains smooth operation at higher cutting speeds. The result is dependable, high-quality threads in tight spaces without frequent tooling changes.
