Carbide Milling Cutter with Straight Shank and Spiral Edge for D1 to D20mm Machining

This carbide milling cutter is a tool designed for metal machining, offering a range of specifications to suit different operational requirements. It is constructed from hard alloy, a material recognised for its application in cutting tools. The tool features a straight shank design and a spiral cutting edge, with availability across multiple model sizes denoted by the D-series. Key dimensional ranges include blade diameter, blade length, and overall tool length, providing options for various machining depths and workpiece dimensions. The product listing includes several model variants, and specific technical details for certain models are available upon consultation.
Features and Construction

The milling cutter is defined by its material composition and its physical design parameters, which determine its application suitability. The available size ranges allow users to select a tool based on the specific cutting diameter and depth required for their project.
Material and Build
The cutter is made from hard alloy. This material is commonly used in tooling for its properties relevant to machining harder workpieces. The tool incorporates a four-slot design and is built with a straight shank, which is a standard interface for many milling machines and holders. The cutting edge is formed into a spiral, a geometry that can influence chip evacuation and cutting forces during operation.
Size and Practical Fit
The product is offered in a series of models with a coded naming convention (e.g., D4, D6, D8). The blade diameter has a broad range from D1 to D20mm, while the blade length varies from 3 to 70mm. The shank diameter is specified from D3 to D20mm, and the full length of the tool extends from 50 to 150mm. This range of dimensions means the tool can be matched to the specific cavity size, depth, and machine compatibility needed for a job.
Uses and Placement

The milling cutter is intended for subtractive manufacturing processes where material is removed to shape a part. Its design parameters make it a candidate for both detailed, small-scale work and larger milling operations, depending on the selected model size.
Event or Professional Use
In professional machining environments such as workshops or manufacturing floors, this tool can be used for tasks like slotting, profiling, and pocketing in metal workpieces. The availability of different diameters (D1-D20mm) allows machinists to choose a cutter appropriate for the required finish and the scale of the feature being machined. The straight shank ensures compatibility with a wide array of standard machine tool holders.
Everyday Home Use
For advanced hobbyists or home workshop users with capable milling equipment, this cutter provides a professional-grade tool option for precision metalworking projects. The range of sizes means one can select a tool for creating precise parts, models, or repairs. It is important for users to verify their machine's compatibility with the straight shank and the power requirements for cutting with hard alloy tools.
Benefits and Buying Value

The value of this milling cutter lies in its specification range and material choice, offering a practical tool for specific machining applications without presuming unsupported performance benefits.
Reuse and Low Maintenance
As a solid tool (Type: 0), it is a single piece not designed for replaceable inserts. Its longevity in use will depend on factors like operating parameters, workpiece material, and maintenance practices such as proper cleaning and storage to prevent damage to the cutting edges.
Why Choose This Product
This product offers a clear range of dimensional options (blade diameter from D1-D20mm, length 3-70mm) within the milling cutter category. The hard alloy material is a stated feature for machining applications. The selection of models, from D4 to D20, provides a direct way to source a tool with a specific size. For precise technical requirements like ball head diameter or chamfering angle, contacting customer service is recommended to confirm model-specific details before purchase.
