Maykestag VHM Solid Carbide End Mill Speedcut Aluminium 4mm Long Series
Professional 4mm 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 4mm cutter combines solid carbide construction with a 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 4mm model, the 4.00mm cutting diameter is followed by a reduced 3.60mm neck diameter, providing additional clearance when machining deeper shoulders, pockets and profiles while retaining the rigidity of a 6mm shank.
Product highlights
- VHM solid carbide construction: Provides excellent rigidity, dimensional stability and cutting-edge durability for professional CNC and production machining.
- Speedcut-Aluminium geometry: Developed specifically around the cutting requirements of aluminium and suitable non-ferrous materials.
- 4mm cutting diameter: Precision 4.00mm cutting diameter manufactured to h10 tolerance.
- Long-series neck-relieved design: Allows additional clearance for deeper profile, pocket and shoulder machining.
- Three-flute geometry: Combines productive metal removal with generous flute space for efficient chip evacuation.
- Unequal spiral angles: The 34°–38° helix arrangement helps interrupt repetitive cutting forces and promotes smoother machining.
- Type W geometry: Cutting geometry suited to softer, long-chipping materials such as aluminium and other suitable non-ferrous materials.
- 45° corner chamfer: A 0.06mm chamfer strengthens the cutting corner and helps protect the edge during machining.
- DIN 6527 L: Manufactured as a long-series end mill according to the specified dimensional standard.
- DIN 6535-HA shank: Cylindrical precision shank for secure concentric clamping in suitable toolholding systems.
- HSC and HPC capable: Designed for modern high-speed and high-performance cutting strategies when the correct machining parameters are applied.
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, a 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 quickly 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 11mm cutting length, making it especially useful for profiling, pocketing and shoulder operations where additional reach is required.
Recommended Applications
The Maykestag Code 7250 range is rated by Maykestag according to its suitability for different material groups. A higher rating indicates greater suitability for the application.

Yellow ring classification
The yellow identification ring on the Code 7250 cutter identifies the Speedcut-Aluminium application family. The geometry of this series is developed primarily around the machining characteristics of aluminium and suitable non-ferrous materials, where efficient chip evacuation and a clean cutting action are particularly important.
What does Type W mean?
Type W identifies a cutting geometry intended for comparatively soft and long-chipping materials. In the Code 7250 range, this geometry works together with the large flute spaces and Speedcut-Aluminium design to promote efficient chip evacuation when machining aluminium and other suitable non-ferrous materials.
Why unequal spiral angles?
The Code 7250 uses different spiral angles between 34° and 38°. Unequal helix geometry changes the timing with which the individual cutting edges engage the workpiece. This helps prevent cutting forces from repeating at exactly the same interval and can reduce vibration, support quieter machining and improve the resulting surface finish.
Understanding the neck-relieved design
The cutting section has a diameter of 4.00mm, while the relieved neck behind it is reduced to 3.60mm. This slight reduction provides clearance between the cutter body and the workpiece. The cutting length is 11mm, while the relieved working section extends to 16mm, allowing additional access when milling deeper shoulders and profiles.
What does DIN 6527 L mean?
DIN 6527 L identifies the dimensional standard and long-series configuration used for this end mill. The longer geometry provides additional reach compared with shorter milling cutters, while the neck relief helps maintain workpiece clearance during deeper machining operations.
45° corner chamfer
The 4mm cutter incorporates a 0.06mm chamfer at 45° on the cutting corner. This small protective chamfer reinforces the cutting edge and helps reduce the risk of premature corner damage while maintaining the geometry required for accurate milling.
