4-Blade Tungsten Steel End Mill for CNC Machining with 1-12mm Cutting Diameter and 50mm Depth

This 4-blade end mill is engineered for CNC milling operations, constructed from tungsten steel to provide a durable cutting edge for material removal. With a cutting diameter range of 1mm to 12mm and a maximum cutting depth of 50mm, it accommodates a variety of milling tasks from fine detailing to deeper cuts. The tool features four effective cutting edges and four slots, which work in tandem to manage chip formation and evacuation during use. A 35° helix angle is incorporated into the design to promote a smoother cutting action and can influence surface finish. The available function lengths, spanning from 3mm to 36mm, offer selection flexibility to match the required reach for different workpiece setups and machining strategies.

Features and Construction

This end mill's design incorporates several specific geometric features that determine its cutting performance and application suitability. The configuration of its cutting edges and flutes is balanced for standard milling operations.

Material and Build

The end mill is made from tungsten steel, a material chosen for machining tools due to its hardness and wear resistance. It has four slots, which correspond to the four cutting edges, providing pathways for chips to exit the cutting zone. The tool is designated as Type 0, indicating a general-purpose end mill geometry without specialised features such as corner radii or specific coatings mentioned in the source data.

Size and Practical Fit

The tool's key operating dimensions include a ball diameter range from 1mm to 12mm, which also defines its contour radius capability for profiling work. Its cutting diameter directly corresponds to this same 1-12mm range. The function length, which is the effective cutting length of the tool, varies between 3mm and 36mm depending on the specific style option selected. A minimum cutting diameter at the centre of 1mm is specified, and the tool includes a 90° chamfer angle at its tip.

Uses and Placement

This end mill is designed for use in computer numerical control (CNC) milling machines. Its specifications make it applicable to a range of machining tasks where precise, controlled material removal is required.

Event or Professional Use

In professional machining environments such as workshops, prototyping facilities, or manufacturing lines, this tool can be employed for milling metals, plastics, or other machinable materials. The range of available sizes, indicated by the style options (e.g., D1.0, D1.5, D2.0 up to D12), allows machinists to select a tool with a specific shank diameter and length to suit the job's requirements, whether for producing small components or larger features.

Everyday Home Use

For advanced hobbyists or makers with access to a CNC milling machine, this end mill enables the creation of precision parts for projects. The smaller diameter options (1mm, 1.5mm, 2mm) are particularly relevant for detailed work in model making, engraving, or crafting intricate designs in various materials.

Benefits and Buying Value

The value of this end mill lies in its specific geometry and material choice, which are suited for controlled milling operations. It provides a tooling solution based on measurable specifications rather than unspecified performance claims.

Reuse and Low Maintenance

As a solid tungsten steel tool, it can be used until the cutting edges are worn, after which it would typically be discarded or potentially re-sharpened by a specialist service if economically viable. No specific maintenance instructions are provided beyond its use in standard machine tool practice.

Why Choose This Product

This product offers a defined set of cutting tool specifications: a 4-edge design, a 35° helix angle, and a clear range of operating diameters and lengths. The availability of multiple style options within a single product listing allows users to select the exact diameter and length combination needed, from D1.0 with a 3mm function length to D12 with a 30mm function length, providing a practical fit for the intended milling task.
