Description
The OSG Threading Tap Metric A-Spiral Flute - Form E Powder Metal Right Hand - TiCN Coated - Blind Holes is a precision tapping tool built for blind-hole applications. It’s ideal for machinists and manufacturing shops that need reliable, repeatable metric threading in challenging deep-hole work.
- Material: Powder metal construction delivers excellent strength and wear resistance for demanding tapping tasks.
- Coating: TiCN coating hardens the surface, reduces friction, and extends tool life during high-speed tapping.
- Flute Design: A-Spiral flute efficiently evacuates chips in blind holes, lowering the risk of tap breakage and improving cutting stability.
- Form E: Extended flute length provides deeper engagement and improved chip clearance for longer blind-hole taps.
- Direction: Right-hand cutting geometry for standard metric threads.
- Size: M4.5 x 0.75 thread profile, suitable for precise, small-diameter applications.
- Standards: DIN371 compliant profile ensures consistent thread form and compatibility with DIN-standard components.
- Applications: Optimized for blind-hole threading in steel, stainless steel, aluminum, and other common machinable metals.
This tap is designed to deliver consistent thread quality and extended service life in deep-hole tapping tasks. The combination of powder-metal strength, TiCN hardness, and an efficient spiral flute helps maintain cutting performance, reduce downtime, and support precise, reliable results in challenging blind-hole projects.
