Solid carbide corner rounding router bit for plastics and aluminum Z2 D12/ I4 L70 S12 R4 RH

Two-flute VHM spiral end mill for rounding from the FVI series 

Index: FVI.12.004.070.12R4

Industrial spiral end mill for rounding made of solid carbide (VHM) from the FVI series. Designed for precision finishing of edges, rounding, chamfering, and grooving on CNC machining centres and overhead spindle milling machines. The tool is made from a special grade of sintered carbide, which ensures extended service life and high resistance to abrasive wear. The profiled blades in a two-flute configuration (Z2) allow for smooth radiused edges without chipping. The ground shank in accuracy class H6 eliminates radial runout, protecting the drive system and ensuring stability during the machining process.

Design advantages and technical properties:

• Special grade of sintered carbide (VHM): Dedicated solid carbide ensures long tool life and resistance to dulling.
• Two-flute Z2 profile design: Two precisely ground rounding blades ensure clean cutting and high surface finish quality.
• Protective coating option: The tool is suitable for coating with protective layers, which increases thermal resistance and extends working time.
• Low shank roughness (Ra ≤ 0.3 µm): Ground shank surface prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing class G2.5: Balancing in accordance with ISO standards ensures stable and quiet operation at high rotational speeds.

Intended use and application range:

The tool is intended for edge rounding, chamfering, and profile grooving operations on CNC machining centres and overhead spindle milling machines.

Used for machining materials such as: soft and hard solid wood, raw and laminated MDF boards, raw particle board, and plywood.
