The OSG Threading Tap Metric Fine A-Spiral Point (M4 x 0.35) is a precision tapping tool designed for through-hole applications, delivering clean, accurate threads with dependable durability for machinists and fabricators.

• Threading Geometry: Metric Fine thread with A-Spiral Point for efficient chip handling and accurate thread formation, right-hand orientation.
• Material: Powder metal body engineered for greater wear resistance and durability under demanding tapping conditions.
• Coating: TiCN coating reduces friction and enhances tool life, improving performance across a range of materials.
• Through-Hole Capability: Specifically designed for through-hole DIN371 applications to ensure consistent threading in open-ended housings and assemblies.
• Size: M4 x 0.35 for fine-pitch, precise threading in compact components and assemblies.
• Chip Evacuation: Spiral point geometry pushes chips forward, promoting smooth cutting and reducing re-cutting or clogging in the thread.

This tap enables dependable, high-precision threading in through-hole parts, suitable for CNC and manual tapping setups. The combination of powder metal toughness, TiCN wear resistance, and efficient chip evacuation translates to longer tool life, fewer reworks, and more consistent thread quality across materials commonly encountered in precision assemblies.
