The OSG Metric A-Spiral Flute Threading Tap, Form E, is a precision tool engineered for reliable internal threading in blind holes. Designed for machinists and fabrication professionals working with small-scale components, it delivers consistent thread quality in tight pockets with lasting durability.

• Size / Thread: M3 x 0.5
• Material: Powder metal construction for high strength and wear resistance
• Coating: TiCN coating increases surface hardness and reduces friction for longer tool life
• Flute design: A-Spiral flute with Form E extended flute length to reach deeper blind holes
• Cutting direction: Right-hand
• Application: Optimized for blind-hole tapping per DIN 376

This combination of extended flute length and a spiral flute pattern enhances chip evacuation, lowering the risk of tap breakage during deep-threading operations. The TiCN coating and powder metal core work together to sustain cutting performance under higher speeds and tougher materials, delivering dependable results across production runs or precision assemblies.
