Carbide grade:MT7 Sub-Micron grade with Titanium Aluminium Nitride multi-layer coating (ISO K10-K20). To be run at medium to high cutting speeds. General purpose for all materials. MTS Threading from ISO M1 x 0.25 and 0-80UN. Working in high cutting speed. Short machining time. Low cutting forces thanks to the short profile. No broken taps. Machining of hardened materials up to 45 HRc. Advantages Enables machining in deep holes. Same tool can produce a wide range of threads and pitches. Same tool can produce both external and internal threads. Coolant through the flutes is very effective for deep holes. Spiral flutes allow smooth cutting action. Shorter machining time due to multi (3 to 5) flutes. Longer tool life due to special triple coating.
