Description
The OSG Threading Tap Metric A-LT-Spiral Flute is a precision tapping solution designed for metric threads in blind holes. Built for machinists who demand reliable performance in deep threading tasks, this TiCN-coated, powder metal tap delivers strong, consistent results and extended tool life.
- Size and thread: M12 x 1.75, right-hand thread for standard metric compatibility
- Material: Powder metal construction delivers high strength and durability in demanding applications
- Coating: TiCN (Titanium Carbo-Nitride) coating reduces friction and enhances hardness for longer wear resistance
- Flute design: LT (Long Taper) spiral flute engineered for superior chip evacuation in deep blind holes
- Application: Specifically optimized for blind-hole threading to minimize formation of chips and improve thread quality
- Machining environment: Suitable for high-speed machining conditions, helping maintain consistency and tool life
The LT spiral flute geometry, paired with a TiCN coating and powder metal body, enables cleaner chip removal and steadier cutting in challenging blind-hole scenarios. This makes it a dependable choice for precision assembly, automotive work, and equipment maintenance where accurate metric threads are essential.
