Master TM UNC Thread Mill with Countersink, 3/4-10 Thread Size, TiAlN Coated

Solid carbide thread milling cutters with irregular cutting edge spacing and an increased number of cutting edges. Due to the irregular cutting edge spacing they achieve very smooth running and long tool life. Newly developed universal geometry and high-performance coating for use across a wide spectrum of materials. - Significantly reduced vibration due to irregular cutting edge spacing. - Increased number of cutting edges. - New coating for optimum wear resistance. - Corrected thread profile for avoidance of profile distortions. Advantage: Incorporating a countersink profile for a 90Deg countersink and thread milling in a single operation. Application: For UNC unified coarse threads ASME-B1.1. Note: Form HB and HE supplied at the same price as HA. Form HB: order with No. 139723 + 129100 HB Form HE: order with No. 139723 + 129100 HE Thread type: UNC Thread type: UNC-LH No. of teeth Z: 6 Threads per inch: 10 Nominal dia DC: 15.9 mm Flute length Lc: 39.29 mm Shank length Ls: 50 mm Overall length L: 120 mm Shank dia Ds: 20 mm
