Drill bit FANAR NAWIERTAK NWRC 2.50 VHM – solid carbide 2.50 mm

FANAR NAWIERTAK NWRC 2.50 VHM is a solid carbide drill bit with a 2.50 mm diameter designed for precision drilling in metalworking and industrial environments. The tool is manufactured from VHM (solid carbide) to provide high hardness and wear resistance, aiming to deliver consistent hole diameters and extended service life under typical machining conditions. It is suitable for both CNC and manual drilling operations where small-diameter, accurate holes are required.

Advantages

The solid carbide construction provides high rigidity and cutting-edge stability, reducing deflection when drilling small diameters. VHM material offers improved wear resistance and a longer lifetime compared with tool steels in many metalworking applications. The 2.50 mm diameter is optimized for fine, precise holes and repeatable performance in batch production or single-part machining.

Suitable for

• Precision drilling in steel and non-ferrous metals
• CNC machining centers and automatic drilling machines
• Manual drilling operations requiring small, accurate holes
• Prototype work and small-batch industrial production

When it may not be suitable

This solid carbide 2.50 mm drill bit is not intended for drilling in very hard or abrasive cast materials without appropriate coatings or specialized grades. It may also be less suitable for applications with severe impact, bending loads or hand-held drilling where tool breakage risk increases due to the small diameter.

Key specifications

• Material: solid carbide (VHM)
• Diameter: 2.50 mm
• Intended use: precision metalworking drilling
• Compatibility: suitable for CNC and manual drilling equipment

How to use

Use appropriate machining parameters for small-diameter solid carbide drills: moderate cutting speeds and steady feed rates suited to the workpiece material. Secure the workpiece and ensure correct alignment in the chuck or collet to minimize runout. Use suitable cutting fluid or coolant for metal drilling to extend tool life and improve chip evacuation. Avoid excessive side loads and pecking only when necessary to clear chips in deep holes.

What to consider before purchase

• Confirm the drill diameter (2.50 mm) matches the required hole size and tolerance.
• Check compatibility with your chuck or tool holder and maximum spindle speed for small carbide tools.
• Assess the workpiece material to determine if a coated or different grade drill is needed for abrasive or hardened metals.

Usage recommendations

For consistent results, run the drill at recommended speeds for carbide tools, use steady feed, and apply cutting fluid appropriate to the metal being machined. Inspect tool condition regularly and replace the drill when wear affects hole quality.
