USER GUIDE MTECS Small Diameter, Short Solid Carbide Thread Mills The MTECS (Mill Thread Endmills Carbide Short) solid This unique tool design offers very precise profiles and carbide thread mills are used for the production of small a high performance IC908 submicron carbide grade internal threads. These thread mills feature with PVD titanium aluminum nitride coating. a short 3-tooth cutting zone with 3 flutes and The very short profile exerts a low force which minimizes a released neck between the cutting zone and tool bending. This facilitates parallel and the shank. high thread precision for the entire length. THREAD MILLING TOOLS Compared to taps, the SOLIDTHREAD is more accurate, thread machining is substantially faster and there is no danger of a broken tap being stuck in the hole. Thread Mill vs. Tap Features Solid Carbide Thread Mills Taps Thread surface quality High Medium Thread geometry Very accurate Medium Thread tolerance 4H, 5H, 6H with std. cutter 6H with standard tap, 4H with special tap Machining time Shorter or same as tap Short Machining load Very low High Range of thread diameters Wide range of diameters Specific tap for each thread size Right-/Left-hand threading Same cutter Specific tap for right- and left-hand Geometric shape Full profile Partial profile Features • Minimum thread size: M1.4x0.3 (1.1 mm bore diameter) up to M20x2.50 • 2xD and 3xD threading lengths • High cutting speeds • Short cycle time • Low cutting forces due to the short contact profile resulting in accurate and parallel thread • Prevents oval threads near thin walls • No more dealing with broken taps • Reliable threading in blind holes • Excellent performance on hardened steel, high temperature alloys and titanium 378 378 378 ISCAR ISCAR ISCAR
