Dormer M4 Thread Metric Standard Machine Tap High Speed Steel Spiral Flute 35° Right Hand E473M4

Dormer E473M4 Metric Standard Machine Tap is engineered for high-precision threading tasks in industrial and manufacturing environments. Crafted from high quality High Speed Cobalt steel (HSS-E-PM), the tap features increased hardness and improved edge strength to deliver long tool life and consistent performance.

The Super-B coating comprising TiAlN and WC/C enhances the tool's durability and provides excellent cutting performance across a range of non-ferrous materials such as brass and copper. Its spiral flute design at a 35° angle allows for effective chip evacuation, reducing swarf build-up and minimizing interruptions during machining operations.

With a right hand thread direction and an overall length of 63mm, this machine tap offers compatibility with standard threading machines. The 4.5mm shank diameter ensures secure mounting and precise control. Conforming to DIN 338 and ISO 529 standards, this threading tap meets stringent quality and tolerance requirements essential for engineering applications.

This tapping tool delivers high wear resistance and resistance to material adhesion, ensuring enhanced productivity and longer intervals between tool changes. The back tapered design further improves chip removal efficiency, making it suitable for medium to high production volumes in manufacturing, automotive, and fluid power industries.
