Carbide milling cutter 4 flute spiral end mill set in hard alloy with straight shank for metal machining, models D4 through D20 with cutting edge length 3-70mm, blade diameter D1-D20mm and shank diameter D3-D20mm
Carbide milling cutter set with hard alloy construction and four-flute spiral design for metal machining

This comprehensive set of carbide milling cutters provides machinists and workshop operators with durable tools for various metal milling applications. The hard alloy material offers enhanced wear resistance compared to standard steel cutters, maintaining a sharper cutting edge through extended use. With models ranging from D4 to D20, these cutters accommodate different scale projects from precision small-part machining to larger milling operations. The straight shank design ensures straightforward compatibility with most standard milling machine collets and holders without requiring special adaptors.
Features and Construction

The cutter's construction centres on practical performance elements that support efficient metal removal. The four-flute spiral design represents a balance between cutting efficiency and chip evacuation, helping to prevent material buildup during extended milling sessions.
Material and Build
Hard alloy forms the cutting edges of these milling cutters, providing inherent wear resistance that helps maintain cutting performance over time. This material selection makes these tools suitable for machining various metals where edge retention matters. The construction does not incorporate coatings or additional surface treatments beyond the base hard alloy material.
Size and Practical Fit
With blade lengths spanning 3mm to 70mm and full lengths between 50mm and 150mm, these cutters accommodate different depth requirements and machine clearances. The blade diameter range from D1 to D20mm and shank diameter from D3 to D20mm allows selection based on both cutting requirements and machine holder compatibility. Specific dimensional details for ball head diameter and chamfering angle require consultation with customer service for precise specifications.
Uses and Placement

These milling cutters serve professionals and workshop environments where metal machining forms part of regular operations. The range of sizes supports everything from detailed precision work to larger-scale material removal tasks across different metals and alloys.
Event or Professional Use
In professional machining environments, these cutters provide reliable tools for repetitive milling operations where tool consistency matters. The availability of multiple models allows workshop managers to maintain appropriate cutter selections for different job specifications. The straight shank design simplifies inventory management since these tools integrate with existing collet systems without requiring specialised holders.
Everyday Home Use
For home workshop enthusiasts with milling capabilities, these cutters offer durable options for metalworking projects. The hard alloy construction provides reasonable longevity even with intermittent use patterns typical of hobbyist machining. The range of sizes supports various DIY and repair projects where metal components require machining or modification.
Benefits and Buying Value

The selection available through different model configurations allows users to choose cutters that match their specific milling requirements without purchasing unnecessary sizes. This focused approach to tool selection supports both cost efficiency and workspace organisation.
Reuse and Low Maintenance
The hard alloy material offers inherent resistance to wear, potentially extending the usable life of each cutter compared to less durable alternatives. Proper storage and handling following standard carbide tool protocols helps maintain cutting performance between uses. No special maintenance requirements exist beyond standard tool care practices for precision cutting equipment.
Why Choose This Product
This milling cutter selection provides a practical range of sizes in a consistently designed tool format. The straight shank across all models simplifies machine compatibility considerations, while the four-flute spiral design represents a versatile cutting geometry suitable for various metals. The availability of multiple configurations allows users to select specific models that match their most frequent milling requirements.
