Carbide milling cutter for metalworking with 4 slots and spiral cutting edge, available in models D4 to D20, featuring straight shank design, ball head diameter from 1-20 mm, blade length 3-70 mm, and full length 50-150 mm for precise machining tasks.
Carbide Milling Cutter for Metalworking with Hard Alloy Construction and Spiral Cutting Edge

This range of carbide milling cutters is designed for professional and workshop metal machining applications. Each tool is fabricated from hard alloy, a material selected for its ability to withstand the abrasion and heat generated during milling operations on metals. The product line offers a practical selection of sizes, with blade diameters spanning from D1 to D20 millimetres and overall tool lengths from 50 to 150 millimetres. This provides users with options for both fine, detailed work and broader material removal tasks. The core design features a spiral cutting edge and a four-slot geometry, which work together to manage chip flow and maintain cutting stability. Specific model details, including exact ball head diameters and chamfering angles, are available through customer service to ensure the correct tool is selected for your machine and material.
Features and Construction

The construction of these milling cutters focuses on durability and functional geometry for metal cutting. The hard alloy material forms the entire cutting body, chosen for its hardness and resistance to wear under the stresses of milling. The physical dimensions provide a range of options to match different project scales and machine capabilities.
Material and Build
The cutter is made from hard alloy, a composite material known for maintaining a sharp edge under the high temperatures and pressures encountered in metal milling. This material choice directly supports the tool's primary function of cutting metal without rapid dulling. The body of the cutter is a single, solid piece of this alloy, machined to precise tolerances for the specified diameters and lengths.
Size and Practical Fit
The available sizes offer significant flexibility. Blade diameters are categorised from D1 to D20 mm, while the shank diameter ranges from D3 to D20 mm, ensuring a secure grip in the tool holder. The full length of the cutter varies from 50 mm to 150 mm, and the cutting blade length itself ranges from 3 mm to 70 mm. This variety allows users to match the tool's reach and cutting depth to the specific requirements of their workpiece and milling machine setup.
Uses and Placement

These cutters are intended for subtractive manufacturing processes on metal workpieces. Their design is suited for operations in machine shops, fabrication workshops, and for use by skilled hobbyists with appropriate milling equipment. The tool's performance is tied to the specific model selected and the machine parameters used.
Event or Professional Use
In professional machining environments, such as CNC milling or manual mill operations, these cutters can be used for tasks like facing, slotting, pocketing, and contouring on metal parts. The availability of different diameters and lengths allows machinists to stock a set of tools for various jobs, from creating small detailed features with a D4 model to removing larger volumes of material with a D20 model.
Everyday Home Use
For advanced home workshops equipped with a milling machine or a capable drill press with a milling attachment, these tools enable precise metalworking for projects like modifying engine parts, creating custom brackets, or machining prototypes. It is essential for users to verify the specific ball head diameter and chamfering angle for their intended application by consulting customer service, as these details affect the cut's profile and finish.
Benefits and Buying Value

The value of this milling cutter lies in its material construction and the range of available sizes, which provide a practical tool for metal cutting tasks. The design prioritises functional geometry over ornamental features, focusing on the core requirement of removing metal efficiently.
Reuse and Low Maintenance
The hard alloy material contributes to the tool's potential for extended use before requiring replacement or re-sharpening, as it resists wear more effectively than standard high-speed steel in many metal cutting scenarios. The tool itself requires no maintenance beyond standard cleaning to remove chips and coolant residue after use, and secure storage to protect the cutting edges.
Why Choose This Product
This product offers a straightforward, purpose-built milling tool for metal. Its key advantage is the hard alloy construction combined with a spiral edge and four-slot design, which are functional responses to the demands of milling. The range of models from D4 to D20, with detailed size combinations like D10x25xD10x75, provides specific options for different machining needs without requiring a custom-made tool for every job.
