- Material and coating: HSS-E (high-speed steel with cobalt) with Steam Oxide coating for enhanced wear resistance and heat tolerance
- Size: No. 10 x 24 (UNC) engineered for through-hole tapping
- Chip evacuation: Spiral point geometry directs chips forward, reducing clogging and improving cutting speed
- Through-hole suitability: Optimized specifically for threading all the way through a workpiece in a single pass
- Precision and durability: Precision-ground cutting edges and robust flute form for clean, repeatable threads and longer tool life
This tap is built to deliver dependable, high-quality threads when you need it most. The combination of HSS-E and a steam oxide finish stands up to repeated use, while the spiral point ensures smooth chip flow and steady contact during cutting. Ideal for production environments and repair work where through-hole threading with consistent results matters, this No. 10 x 24 UNC taps into reliable performance that helps you complete critical machining tasks efficiently.
