THREAD MILLING TOOLS USER GUIDE MTECS Small Diameter, Short Solid Carbide Thread Mills The MTECS (Mill Thread Endmills Carbide Short) solid carbide thread mills are used for the production of small internal threads. These thread mills feature a short 3-tooth cutting zone with 3 flutes and a released neck between the cutting zone and the shank. This unique tool design offers very precise profiles and a high performance IC908 submicron carbide grade with PVD titanium aluminum nitride coating. The very short profile exerts a low force which minimizes tool bending. This facilitates parallel and high thread precision for the entire length. 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 ISCAR
