FANAR solid carbide end mill, diameter 2.0 mm, radius R1.0, 4/50 length config, 2 flutes, VHM, model B230

FANAR solid carbide end mill with a 2.0 mm cutting diameter and R1.0 corner radius, model B230, is a full-carbide (VHM) tool designed for precision milling in metalworking and toolmaking. The tool features a 4/50 length configuration and a 2-flute geometry that balances chip evacuation and surface finish for small-diameter slotting, pocketing and fine finishing tasks. The compact geometry and carbide construction provide rigidity and wear resistance required for machining small features and tight tolerances.

Advantages

The VHM solid carbide construction offers high stiffness and thermal stability compared with coated high-speed steel, improving tool life during precision metal cutting. The 2-flute design improves chip clearance in through-cuts and shallow pockets while helping to maintain a smooth surface finish. The R1.0 radius reduces stress concentration at corners and enables better tool engagement for fillet and radius profiling. The 4/50 length configuration reduces overhang for increased rigidity when machining deep features with a small diameter.

Suitable for

• Small-diameter slotting in steel and non-ferrous alloys
• Pocketing and machining of fine cavities in toolmaking
• Finish milling and profiling with a 1.0 mm corner radius
• Operations requiring high positional accuracy and minimal deflection

When it may not be suitable

This 2.0 mm solid carbide tool is not intended for heavy roughing or high material removal rate operations where larger diameters and more robust geometries are required. Extremely long overhangs or interrupted heavy cuts may cause rapid wear or tool breakage despite the carbide construction.

Key specifications

• Cutting diameter: 2.0 mm
• Corner radius: R1.0
• Number of flutes: 2
• Material: solid carbide (VHM)
• Length configuration: 4/50 (short overhang relative to cutting length)

How to use

Select appropriate spindle speed and feed per tooth for the workpiece material; small-diameter carbide tools typically require higher spindle speeds and conservative feeds per tooth to avoid overload. Ensure secure workholding and minimize tool overhang to reduce deflection. Use coolant or appropriate minimum quantity lubrication for the machined material as required to manage heat and chip evacuation. For best results when slotting or pocketing, program steady axial engagement and avoid sudden tool entry or excessive radial immersion.

What to consider before purchase

• Verify compatibility with your machine spindle and collet system for 2.0 mm shank clamping
• Confirm that the tool geometry (2 flutes, R1.0) matches your intended operation and material
• Assess required tool life and whether carbide is appropriate for your cutting conditions
• Plan cutting parameters (speed, feed, coolant) for small-diameter carbide tools

Usage recommendations

Use the FANAR 2.0 mm VHM end mill for precision finishing and fine feature machining with minimal overhang, set high spindle speeds with conservative feed per tooth, and maintain stable clamping to achieve best surface quality and tool life.
