OSG Threading
TX-SFT High Performance Spiral Fluted Tap
Workpiece material (ISO)
P · Steel
High-performance spiral fluted tap for fast, stable threading of steel and alloy steel — engineered for reliable blind-hole tapping with long tool life.
Features & uses
Engineered for performance
1
High-strength thread design
A special high-strength thread profile raises overall thread strength and prevents early breakage.
2
New flute geometry
A newly shaped flute curls chips stably and lowers the risk of chip entanglement.
3
TP-Coating
An exclusively developed coating with excellent wear resistance and lubricity, extending tool life.
4
OSG variable lead (patented)
An unequal lead at the flute end improves chip evacuation when tapping blind holes.
