Our Metric Multitooth Straight Flute Coolant Through Thread Mills – Solid Carbide are built for high-performance internal threading with unmatched durability and precision. Crafted from premium submicron grade carbide, these tools offer exceptional strength and wear resistance, making them ideal for demanding machining environments. Each flute is individually cooled through internal coolant channels, ensuring optimal chip evacuation and reduced heat buildup during operation. The advanced AlTiN+ coating enables higher cutting speeds while extending tool life, especially in ferrous materials. Designed exclusively for internal threads, these multitooth tools cut multiple threads per pass, significantly reducing cycle time while delivering clean, accurate results.
