Description
The OSG Metric Spiral Flute Threading Tap is a precision tool designed for accurate ISO metric threading in blind holes. Built for professionals who demand consistent thread quality, its HSS-E composition and Steam Oxide Coated Plus finish deliver reliable performance in demanding applications.
- Thread size: M8 x 1.25
- Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and durability
- Coating: Steam Oxide Coated Plus to reduce friction and improve wear resistance
- Flute design: Metric spiral flute optimized for effective chip removal in blind holes
- Application: Specifically engineered for threading blind holes in metal workpieces
- Cutting edges: Precision-ground edges that deliver accurate thread forms and clean finishes
By delivering clean, precise threads with reliable repeatability, this tap minimizes rework and extends tool life in production environments. The spiral flute geometry ensures steady chip evacuation, reducing heat buildup and the risk of chip clogging in blind holes. With cobalt-enhanced HSS-E and a durable Steam Oxide finish, the tap maintains sharpness over extended use, making it a dependable choice for threading M8 x 1.25 in metal components such as housings, fixtures, and assemblies.
