## Summary description

Solid carbide drill bit FANAR WIERTLO WDG FI 4,20 M 5 VHM TIALN with a 4.20 mm diameter. Designed for precision drilling in metal and other hard materials, featuring VHM (vollhartmetall) construction and TiAlN coating for improved wear resistance and thermal stability. Suitable for use in handheld drills and machine tools for production and maintenance tasks.

## Long description

Solid carbide drill bit FANAR WIERTLO WDG FI 4,20 M 5 VHM TIALN is a precision 4.20 mm diameter cutting tool engineered for drilling metal and other hard materials. Constructed from full hard metal (VHM), the drill delivers rigidity and dimensional stability for repeatable hole quality. The TiAlN (titanium aluminum nitride) coating increases surface hardness and thermal resistance, extending tool life during high-speed and interrupted cutting operations. The geometry and manufacturing tolerances support use in both handheld drills and machine tools for production and maintenance.
Advantages
The full-carbide construction provides high stiffness and reduced deflection for accurate hole position and diameter. TiAlN coating improves wear resistance, reduces edge breakdown and maintains hardness at elevated temperatures, allowing sustained cutting performance under heavier feed or higher spindle speeds. The drill’s precise diameter and ground flute geometry promote efficient chip evacuation and stable cutting conditions, contributing to longer tool life and consistent hole finishes.
Suitable for
Drilling through steel and stainless steel
Working with hardened or tough alloys
Precision maintenance and machine shop tasks
Production drilling in jigs and fixtures
Use in handheld drills and CNC or handheld machine tools
Key specifications
Material: solid carbide (full hard metal, VHM)
Coating: TiAlN (titanium aluminum nitride)
Diameter: 4.20 mm
Shank type: straight cylindrical shank suitable for standard drill chucks and collets
Geometry: ground flutes for precision drilling and improved chip evacuation
How to use
Select the correct spindle speed and feed rate according to the workpiece material and machine capability; start with conservative parameters when first using the tool. Secure the drill in an appropriate chuck or collet to minimize runout. Use cutting fluid or coolant where recommended for the workpiece material to reduce temperature and improve chip removal. Apply steady, controlled feed and avoid excessive pecking unless required for deep holes; retract periodically if chips accumulate. Inspect holes and tool wear regularly and replace the drill when edge chipping or dimensional degradation is observed.
Usage recommendations
For best results when drilling steels and stainless steels, use moderate cutting speeds with sufficient coolant and maintain minimal runout in the holder. When working with hardened alloys, reduce feed, monitor tool wear closely, and replace the drill before significant edge damage occurs to preserve hole quality.
