Description
Introducing the OSG Threading Tap Metric A-Spiral Flute—designed for precise metric threading in blind holes. Built for machinists and engineers working on compact parts, it combines durable powder-metal construction with a TiCN coating to deliver reliable, long-lasting performance.
- Size / Thread: M3 x 0.5, metric tapping standard for small components
- Flute design: A-spiral flute enhances chip evacuation, reducing clogging in blind-hole tapping
- Material: Powder metal construction delivers improved wear resistance and durability
- Coating: TiCN coating creates a harder surface, lowering friction and extending tool life
- Shank: HB Weldon shank provides stable seating and repeatable alignment, reducing runout
- Hand: Right-hand threading matches conventional tapping operations
- DIN standard: Complies with DIN 371/1835 for reliable interchangeability
- Application: Ideal for threading metric blind holes in electronics, automotive, and precision parts
With its spiral flute and TiCN-coated powder-metal construction, this tap delivers smoother cuts, diminished chip buildup, and fewer broken taps when working in blind-hole applications. The HB Weldon shank locks firmly in the holder, promoting consistent torque transfer and hole quality. The coating and material choice work together to resist wear in challenging materials, helping you complete more holes per tap and reduce downtime. This tap is a practical choice for high-precision assemblies where clean, accurate M3 x 0.5 threads are essential.
