Widin Carbide Corner Radius End Mill is a precision milling tool designed for machinists tackling hard materials and detailed radii. This 3 mm diameter, 12 mm length-of-cut end mill with a 0.3 mm corner radius delivers reliable, repeatable results in compact CNC work.

• Diameter x LOC: 3 mm diameter with 12 mm length of cut (LOC) for compact, rigid cutting in tight work envelopes.
• Corner Radius: R0.3 mm to create precise radii and clean, well-defined corners on hard materials.
• Flutes: 4-flute configuration balances material removal, finish quality, and stability during cutting.
• Cutting Length / Geometry: Stub-cut length enhances rigidity and reduces tool deflection under load.
• Material: Solid carbide construction delivers wear resistance and consistent performance on high-hardness workpieces.
• Series / Design Intent: Part of the ZR704 family, engineered for corner-radius end milling with reliable results across demanding applications.
• Applications: Ideal for finishing pockets, contours, and shoulders where controlled radii and sharp corners are required.

Designed to tackle high-hardness workpieces with dependable machinability, this end mill enables precise radii and sharp corners without sacrificing rigidity. The 4-flute stub-cut geometry supports stable cutting at small diameters, helping you achieve smooth finishes and accurate depth control in CNC milling. Whether you’re refining a pocket contour or defining a tiny fillet, this tool delivers repeatable results with a clean edge and durable carbide construction.
