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

Product information

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. What is a corner radius end mill? A corner radius end mill combines a flat-bottomed cutting profile with a controlled radius at the cutting edge corners. This reduces the sharp corner found on a conventional square end mill, improving edge strength and helping the cutter produce smooth transitions between walls and floors. Corner radius geometry is particularly useful for profiling, slotting, pocketing, contouring and general-purpose milling where both productivity and edge durability are important. Product highlights • Speedcut Universal: Maykestag's high-performance universal solid carbide milling solution for demanding machining applications. • 20.00mm cutting diameter: Large-diameter geometry for productive material removal and finishing. • 1.00mm corner radius: Strengthens the cutting edge and produces controlled transitions between machined surfaces. • Four-flute design: Four cutting edges provide a productive balance between cutting capacity, stability and surface finish. • Unequal 35°–38° spiral angles: Variable helix geometry promotes smooth, vibration-reduced running and very good surface quality. • ALUNIT-S coating: Wear-resistant coating for demanding carbide milling applications. • Solid carbide construction: High rigidity and dimensional stability for precision milling. • Long-series, necked design: Provides extended reach and additional clearance around deeper contours and recessed features. • DIN 6527L: Long solid carbide milling tool configuration. • DIN 6535-HA shank: Cylindrical shank configuration for compatible milling toolholders. • 20mm h6 shank: Precision shank diameter for accurate toolholding. • Universal machining: Suitable for fine finishing, finishing, rough-finishing and roughing operations. • High cutting performance: Designed to achieve high material-removal performance while maintaining good surface quality. Why Choose Maykestag? Maykestag specialises in precision-manufactured professional cutting tools where controlled geometry, accurate tolerances and carefully selected carbide grades and coatings are essential. In universal milling, the ability to perform multiple machining stages with one tool can simplify tool selection while maintaining consistent machining results. The Code 6447 Speedcut Universal combines four-flute corner radius geometry, unequal 35°–38° spiral angles, solid carbide construction and ALUNIT-S coating in a versatile tool designed for universal milling. The 20mm version provides substantial cutting capacity while retaining the controlled geometry required for finishing and contouring operations. 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.
