This is a versatile MTTX spiral flute metric coarse machine tap designed for machining metric coarse threads in blind holes across various materials. This machine tap features a powder metallurgical HSS-E material with a steam-tempered surface finish, making it ideal for 2.5xD through-hole threading in general-purpose applications. The spiral point geometry conforms to ISO 529 tap standards, ensuring reliable performance. Notably, this tap is suitable for threading in steel, including soft steel, construction steel, carbon steel, alloyed steel, and hardened and tempered steel.

• The spiral point geometry ensures efficient chip evacuation during threading, reducing the risk of clogging and improving overall performance
• The tap’s heat-treated material enhances durability, allowing it to withstand demanding machining conditions
• The Dormer E001M24 is suitable for creating threads in steel with a depth of up to 2.5 times the tap diametre
• The visually distinctive blue coating provides corrosion resistance and aids in identifying the tap type

• Machining soft steel making it ideal for general steel applications
• Carburised construction steel makes it suitable for structural steel components
• Carbon steel is effective for various carbon steel materials
• Alloyed steel is versatile for alloyed steel alloys
• Hardened and tempered alloy steel is designed for tougher steel grades

No, this tap is not recommended for stainless steel due to its specific properties and hardness.

The square drive adapter measures 18 mm.

Yes, it can be used for blind holes, but ensure proper chip evacuation.
