Description
The OSG Metric Spiral Point Threading Tap is a precision tapping tool built for through-hole metalwork. Designed for machinists who demand consistent, accurate M4 x 0.7 threads, it combines durable construction with efficient chip removal for steady throughput.
- Thread Size & Pitch: M4 x 0.7 through-hole tapping tap, optimized for metric threads in through-hole applications.
- Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance during demanding cuts.
- Coating: Steam oxide coating to reduce friction, improve lubricity, and extend tool life in tough materials.
- Geometry: Spiral point design to promote fast chip evacuation and clean thread formation in through holes.
- Application: Specifically engineered for through-hole threading on a range of metals, with reliable performance in production and repair work.
- Brand: OSG, a trusted name in precision threading tools known for consistency and durability.
This tapping solution delivers cleaner threads, reduces binding, and extends tool life thanks to its cobalt-enhanced steel and protective steam oxide coating. The spiral point geometry minimizes chip buildup in through holes, helping you achieve repeatable thread quality with fewer reworks. Ideal for shops and job sites that prioritize reliability and efficiency in small-diameter metric threads.
