Drill bit FANAR Wiertło weglik Ø4.50 mm, 24/66 mm, 3xD, HA6 VHM X-Drill

FANAR solid carbide drill bit with a 4.50 mm diameter is designed for precision metalworking and general drilling tasks. The bit is available with overall lengths of 24 mm and 66 mm and a working depth of 3xD, providing a balance between rigidity and reach. Made from HA6 grade VHM (solid carbide) and featuring X-Drill geometry, the tool improves chip evacuation and centring for consistent hole quality in through and blind holes in steels and other alloys.

Advantages

The VHM carbide substrate offers high hardness and wear resistance for extended tool life in production and maintenance use. X-Drill geometry enhances chip removal and reduces tendency to clog, while the 3xD ratio ensures repeatable accuracy without excessive deflection. Available in short and long overall lengths, the drill can be selected to match fixture constraints and depth requirements.

Suitable for

• Drilling through and blind holes in alloy and carbon steels
• Production machining and maintenance operations
• Precision drilling requiring good centring and surface finish
• Applications needing reliable chip evacuation in small diameters

Key specifications

• Material: solid carbide (VHM), HA6 grade
• Diameter: 4.50 mm
• Available overall lengths: 24 mm and 66 mm
• Working depth: 3×D (three times the diameter)
• Geometry: X-Drill for improved centring and chip evacuation
• Use type: suitable for through and blind holes

How to use

Select the overall length that fits the fixture and the hole depth, clamp the drill securely in an appropriate holder or collet, and use recommended spindle speeds and feed rates for the workpiece material. Start with a centre mark or pilot if precise positioning is required. Ensure stable workpiece clamping to minimise runout and use coolant or cutting fluid suitable for carbide tooling to extend tool life and improve surface finish.

Usage recommendations

For best results, use cutting parameters tailored to the specific steel or alloy grade, maintain correct runout limits, and employ steady coolant flow to facilitate chip evacuation. Choose the shorter overall length for maximum rigidity and the longer option when additional reach is necessary.
