Dormer E557 HSS Spiral Flute Tap

This M3 spiral flute tap with 0.5mm pitch is the smallest in the range, specifically designed for precision threading work on smaller components. Perfect for electronics enclosures, instrumentation, delicate mechanisms, and fine fabrication work, this tap excels where accuracy and control are paramount.

The compact 3.15mm connection diameter and 48mm overall length make this tap ideal for accessing confined spaces and working on smaller assemblies. Despite its diminutive size, the three-flute spiral design still provides effective chip evacuation from blind holes, ensuring clean threads even in challenging materials.

This tap is equally valuable for professional precision engineering workshops and home hobbyists working on model engineering, electronics projects, or detailed metalwork.

Features and Benefits:
• Compact dimensions for precision work on small components
• HSS construction maintains cutting edge integrity at fine pitches
• Spiral flutes prevent chip jamming in small diameter holes
• Fine 0.5mm pitch delivers smooth, accurate M3 threads
