The Scientific Cutting Tools SPTM745XL Uncoated Solid Carbide Single Profile Thread Mill is engineered for precision internal and external thread generation in demanding metalworking applications. Built as a 1-1/4 inch single profile thread milling cutter, it provides accurate thread form control across a wide TPI range. Its 1.250 inch diameter thread mill geometry supports robust threading in large bore and industrial component machining. The solid carbide body ensures exceptional rigidity, wear resistance, and dimensional stability during long CNC cycles. Featuring a 0.750 Shank Carbide Cutter for CNC Machining, this tool offers strong clamping support and vibration control in high-torque threading operations. The extended 3.250 LOC Thread Mill for Precision Threading allows deeper thread milling passes while maintaining thread consistency. With six flutes, it improves chip evacuation and supports smoother thread interpolation in tougher materials. As an Uncoated Carbide Threading Tool for Metalworking, it performs efficiently in cast iron, alloy steel, stainless steel, and non-ferrous metals where coating is not required. The 6 Inch Overall Length Thread Mill for Industrial Use provides extra reach for deep cavity and hard-to-access threading jobs. Its 0.400 inch neck diameter improves clearance in confined bores and internal thread paths. This industrial internal threading milling cutter supports minimum 1-1/4 inch internal threads with 4 to 8 TPI internal limits. It also handles external threading applications within 6 to 10 TPI ranges. Machinists rely on this single profile design for versatile pitch flexibility and excellent thread accuracy. It is especially effective in aerospace, heavy equipment, and precision repair applications. The SPTM745XL is a dependable solution for clean, accurate, and repeatable thread milling performance.
