Description
The OSG Threading Tap is a precision metric fine-thread tap designed for through-hole work, engineered for machinists who demand reliable, accurate threads in compact components. With a TiCN-coated powder-metal body and A-Spiral Point geometry, it delivers long tool life and smooth, high-precision threading.
- Size & Thread: M4.5 x 0.5 metric fine thread for small, high-precision holes.
- Geometry: A-Spiral Point design pushes chips forward for cleaner cuts and faster cycle times.
- Material: Powder metal construction offers improved wear resistance and heat tolerance under demanding conditions.
- Coating: TiCN coating reduces friction, enhances chip evacuation, and extends tool life.
- Through-Hole Design: Optimized for through-hole tapping in DIN371 applications with consistent thread formation.
- Hand: Right-hand threading matches standard assembly practices across common materials.
This tap is ideal for precision threading across a wide range of materials, supporting high-speed, high-accuracy operations. The combination of a tough powder-metal body and the low-friction TiCN coating helps maintain sharpness longer, reducing rework and improving consistency in every part. Whether you’re producing small fasteners, electronics housings, or automotive components with through holes, this tap delivers dependable performance and predictable results.
