The TIN-SFT DIN371 M4\*0.7 machine tap is a precision tool for creating internal threads with a 4 mm diameter and 0.7 mm pitch. It is manufactured according to the DIN371 standard and features a left-hand spiral flute design, making it ideal for blind holes. The TiN Titanium Nitride surface coating increases wear resistance and extends tool life. The overall length of the tap is approximately 63 mm, with a thread-cutting length of around 13 mm. The spiral angle of the flutes typically ranges between 35 and 45 degrees to optimize chip evacuation in blind hole applications. This tap is fully compatible with CNC machines and precision drilling systems.
The tool material is typically high-speed steel HSS or alloyed HSS-E, selected for its high thermal resistance. The precise flute design improves thread surface quality and reduces cutting force. The TIN-SFT DIN371 M4\*0.7 machine tap is suitable for machining aluminum, carbon steels, copper alloys, and cast iron. It is widely used in high-precision industrial environments and mass production lines. The high manufacturing accuracy ensures standard thread tolerance and prevents dimensional mismatches. This tap helps increase production speed and reduce tool breakage rates in demanding applications.
