MAYKESTAG Speedcut Universal Solid Carbide Corner Radius End Mill 20.00mm R1 Z4 ALUNIT-S

Maykestag Speedcut Universal Solid Carbide Corner Radius End Mill 20.00mm R1 Z4 ALUNIT-S

High-performance 20mm Maykestag Speedcut Universal solid carbide corner radius end mill with 1mm radius, four flutes, unequal 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 including finishing, rough-finishing and roughing with one versatile tool.

The Maykestag Code 6447 Speedcut Universal is a high-performance solid carbide corner radius end mill for universal machining applications. This 20.00mm version features a precise 1.00mm corner radius, four cutting edges and unequal spiral angles of 35°–38°. The variable spiral geometry promotes smooth, vibration-reduced running and supports excellent surface quality during demanding milling operations.

Manufactured from solid carbide and finished with a ALUNIT-S coating, the tool combines high rigidity with increased wear resistance. The long, necked geometry provides additional clearance and reach, while the 20mm h6 cylindrical shank conforms to DIN 6535-HA. Maykestag specifies the tool for universal use covering fine finishing, finishing, rough-finishing and roughing operations with one tool.

Designed for Productive Universal Milling

The 1mm corner radius provides a stronger cutting edge than a sharp-cornered square end mill while allowing the tool to machine walls, floors and transitions efficiently. This makes the Speedcut Universal useful for profiling, pocketing, contouring and general-purpose milling operations.

The unequal 35°–38° spiral angles are designed to produce a smooth, vibration-reduced cutting action and very good surface quality. Combined with the four-flute geometry, long necked design and ALUNIT-S coating, the Code 6447 is intended to provide high cutting performance across a broad range of professional milling applications.
