MAYKESTAG Speedcut Universal Solid Carbide Ballnose End Mill 20.00mm R10 Z4 ALUNIT-S

Maykestag Speedcut Universal Solid Carbide Ballnose End Mill 20.00mm R10 Z4 ALUNIT-S

High-performance 20mm Maykestag Speedcut Universal solid carbide ballnose end mill with 10mm radius, four flutes, variable 35°–38° spiral angles and ALUNIT-S coating. The long-series, necked design with DIN 6535-HA cylindrical shank is designed for universal milling applications where controlled cutting performance, smooth running and excellent surface quality are required.

The Maykestag Code 7357 Speedcut Universal is a high-performance solid carbide ballnose end mill designed for universal machining applications. This 20.00mm version features a 10mm ballnose radius, four cutting edges and unequal spiral angles of 35°–38°. The variable spiral geometry helps promote smooth, vibration-reduced running and consistent machining performance across a broad range of materials.

Manufactured from solid carbide and finished with a ALUNIT-S coating, the tool combines high rigidity and wear resistance with a long-series, necked geometry. The 20mm shank is manufactured to h6 tolerance and uses a DIN 6535-HA cylindrical shank. The 20mm version has an overall length of 104mm, an effective cutting length of 30mm and a 54mm neck length.

Designed for Smooth Contouring and Profiling

The ballnose geometry of the Speedcut Universal allows the cutter to follow curved surfaces and three-dimensional contours while maintaining a consistent cutting radius. The unequal 35°–38° spiral angles are designed to promote a smooth, vibration-reduced cutting action, supporting good machining stability and surface quality.

The long, necked configuration provides additional clearance and reach when machining recessed or contoured features. With its four-flute construction, solid carbide body and ALUNIT-S coating, the Code 7357 is suited to a broad range of professional milling operations.
