Carbide milling cutter set with straight shank and spiral cutting edges, available in multiple metric models from D4 to D20, featuring four slots and blade lengths from 3-70 mm for precision metalworking applications.
Carbide Milling Cutter Set with Straight Shank and Spiral Cutting Edges for Metal Machining

This comprehensive set of milling cutters is designed for machinists, engineers, and workshop professionals engaged in precision metalworking. Constructed from hard alloy, these tools are engineered to tackle the demands of milling ferrous and non-ferrous metals, providing a selection of sizes to match specific job requirements. The availability of models from D4 to D20 in diameter, coupled with varying blade and full lengths, allows for tailored tool selection based on the depth of cut and the milling machine's capabilities. The straight shank design ensures a reliable fit in standard collets and chucks, making these cutters a practical addition to any workshop's tooling inventory.
Features and Construction

The core design of these milling cutters focuses on functionality and compatibility with common workshop equipment. Each cutter is built to provide a balance between cutting performance and tool life, using materials and geometries suited to metal removal.
Material and Build
The cutters are fabricated from hard alloy, a category of materials known for high hardness and wear resistance. This makes them suitable for machining operations where the tool edge must withstand significant pressure and heat without rapidly degrading. The construction includes four slots, a common feature that contributes to the cutter's structure and chip flow.
Size and Practical Fit
The product offers a practical range of sizes to cover various milling applications. Blade lengths span from 3 mm for very fine work up to 70 mm for deeper cuts, while blade diameters are categorised from D1 to D20 mm. The shank diameter corresponds to the cutter size, ranging from D3 to D20 mm, ensuring a proportional and secure mounting interface. Full lengths from 50 mm to 150 mm provide the necessary reach for different milling setups and workpiece geometries.
Uses and Placement

These cutters are intended for use in milling machines to shape metal components. The specific model selection allows users to match the tool to the task, whether in a professional manufacturing environment or a dedicated hobbyist workshop.
Event or Professional Use
In professional CNC or manual milling contexts, selecting the correct cutter diameter and length is critical for achieving the desired tolerances and surface finish. The listed models, such as the D10x25xD10x75, provide specific dimensional combinations. The spiral cutting edge form aids in producing a smoother cut surface and more efficient chip removal compared to straight-flute designs, which can be particularly beneficial in automated or high-volume production runs.
Everyday Home Use
For the advanced home workshop or machining enthusiast, having a set of durable, size-specific cutters like these enables a wider range of projects. The straight shank design is compatible with most benchtop milling machines and rotary tools with appropriate holders, making them accessible for prototyping, model making, or repairing metal parts.
Benefits and Buying Value

The value of this product lies in its material specification and the clarity of its size offerings, allowing for informed tool selection without guesswork.
Reuse and Low Maintenance
Hard alloy tools are valued for their potential for extended use before requiring sharpening or replacement under appropriate operating conditions. The clarity of the size specifications – blade diameter, length, shank diameter, and full length – helps users select the right tool for the job the first time, reducing the risk of tool damage from misuse and supporting longer service life.
Why Choose This Product
This product provides a clearly specified range of carbide milling cutters with a functional straight shank and spiral edge design. The explicit model listing (e.g., D4x10xD4x50, D6x15xD6x50) removes ambiguity about the dimensions you are purchasing. For applications requiring specific ball head profiles or chamfering angles, the instruction to consult customer service provides a direct path to obtaining the necessary technical details before committing to a purchase.
