The Hertel M4x0.7 Metric Thread Forming Tap is a precision machining tool designed for creating clean threads without generating chips. Made from high-quality high-speed steel with a bright/uncoated finish, this tap delivers consistent performance across various materials. The plug chamfer design makes it versatile for both through holes and blind holes with adequate bottom clearance. With a 3/4" thread length and 2-1/8" overall length, this tap provides the perfect balance of reach and stability for professional applications. The D6 thread limit ensures precise threading that meets industry standards. This Hertel tap (Part #010452AS) stands out for its ability to form threads by displacing material rather than cutting it, resulting in stronger threads with improved fatigue resistance. An essential tool for machinists and manufacturing professionals who demand reliability and precision in their metric threading operations.
