Maykestag VHM Solid Carbide End Mill Speedcut Aluminium 12mm Long Series
Professional 12mm VHM solid carbide Speedcut-Aluminium end mill with a long-series neck-relieved design, three flutes, Type W geometry, unequal 34°–38° spiral angles and a 45° corner chamfer for efficient high-performance milling of aluminium and other suitable non-ferrous materials.
The Maykestag Code 7250 Speedcut-Aluminium series is engineered for productive machining where efficient chip evacuation, stable cutting and a high-quality surface finish are essential. This 12mm cutter combines solid carbide construction with three-flute cutting geometry and unequal spiral angles of 34°–38°, helping produce a smooth cutting action while reducing the tendency for vibration during demanding milling operations.
The long-series construction incorporates a relieved neck behind the cutting section. On this 12mm model, the 12.00mm cutting diameter is followed by a reduced 11.50mm neck diameter, providing additional clearance when machining deeper shoulders, pockets and profiles while retaining the rigidity of a 12mm shank.
What is a neck-relieved solid carbide end mill? A neck-relieved end mill has a reduced diameter immediately behind the cutting section. This provides additional clearance between the cutter body and the workpiece when machining deeper profiles, shoulders or cavities. The Code 7250 combines this clearance with the rigidity and wear resistance of VHM solid carbide, making it particularly useful where accurate machining and controlled cutting are required.
Product highlights

Why Choose Maykestag?
Maykestag is an Austrian cutting-tool specialist focused on precision-manufactured tools for professional machining. Accurate tool geometry, controlled tolerances and application-specific cutting designs are particularly important when machining aluminium, where chip evacuation, cutting-edge sharpness and vibration control can have a major influence on surface finish and productivity.
The Code 7250 Speedcut-Aluminium series combines solid carbide construction, Type W cutting geometry, unequal helix angles and neck relief in a cutter specifically developed for productive machining of aluminium and suitable non-ferrous materials.
Built for High-Performance Aluminium Milling
Aluminium machining requires a cutter capable of removing chips efficiently without allowing them to interfere with the cutting edges. The three-flute configuration of the Code 7250 provides an effective balance between flute space and cutting-edge engagement, while the unequal 34°–38° spiral geometry helps promote smooth cutting and reduced vibration. The relieved neck extends the cutter's working clearance beyond its 26mm cutting length, making it especially useful for profiling, pocketing and shoulder operations where additional reach is required.
