The OSG Metric Fine A-Spiral Threading Tap is engineered for precision tapping in metric blind holes, making it ideal for machinists and assembly shops that demand accurate, durable threads in confined spaces. Designed for reliable performance with DIN374 standards, it delivers clean, consistent results in demanding applications.
- Size / Pitch: M12 x 1.25 for fine-thread applications in metric hardware
- Flute Design: A-Spiral flute for efficient chip evacuation and reduced risk of clogging
- Material: Powder metal substrate built for toughness and extended tool life
- Coating: TiCN coating increases hardness, lowers friction, and sustains performance at higher speeds and temperatures
- Thread Type: Right-hand thread compatible with standard fasteners
- Application: Optimized for blind holes per DIN374, delivering precise thread depth and finish
- Compatibility: Suitable for both CNC and manual tapping workflows
This combination of a robust powder-metal core, hard TiCN surface, and an efficient spiral flute translates to longer wear life, fewer insert changes, and more consistent thread quality across a range of materials. The tap excels in tight spaces where chip clearance matters, helping you avoid built-up material that can compromise thread integrity. Whether you’re assembling precision components or fabricating durable housings, this tap provides reliable performance and repeatable results.
