FANAR solid-carbide drill bit WIERTLO WEGLIK, diameter 2.50 mm, length 31/57 mm

FANAR solid-carbide drill bit WIERTLO WEGLIK with a 2.50 mm cutting diameter and overall dimensions 31/57 mm is a precision tool designed for accurate holemaking in metals and other hard materials. Manufactured from cemented carbide (VHM), this drill bit provides high stiffness and wear resistance required for small-diameter drilling operations. It is intended for use in CNC machines, drill presses and production environments where repeatable, precise holes are needed.

Advantages

The solid-carbide construction ensures greater rigidity and reduced deflection compared with high-speed steel drills, enabling consistent hole geometry and improved surface finish. Carbide material offers superior wear resistance for longer tool life in abrasive or hard materials. The small 2.50 mm cutting diameter combined with the compact 31/57 mm dimensions makes the bit suitable for confined workspaces and for producing fine, accurate holes with minimal runout.

Suitable for

• Precision drilling in steel, stainless steel and non-ferrous metals
• CNC machining of small-diameter holes
• Drill-press operations in industrial production
• Applications requiring repeatable, tight-tolerance holes

Key specifications

• Cutting diameter: 2.50 mm
• Overall length / flute length: 31/57 mm
• Material: cemented carbide (VHM)
• Tool type: solid-carbide twist drill
• Intended use: drilling in metals and hard materials

How to use

Install the drill bit securely in the machine chuck or collet to minimize runout. Select appropriate spindle speed and feed rate for a 2.50 mm carbide drill in the workpiece material; use lower speeds and controlled feeds for harder alloys. Apply cutting fluid or coolant as recommended for metal drilling to extend tool life and improve chip evacuation. Use peck drilling cycles when deep holes or long chips are expected, and inspect hole quality periodically during production runs.

Usage recommendations

For best performance, use the drill in rigid setups with minimal overhang, maintain correct coolant application, and monitor wear to replace the bit before geometry degradation affects hole tolerance.
