Drill Bit FANAR WIERTLO NC 90 FI 8.00 mm VHM, 16/63 mm shank/length

FANAR WIERTLO NC 90 FI solid carbide drill bit with an 8.00 mm cutting diameter is designed for precision metalworking. Constructed from VHM (solid carbide), the tool provides high rigidity and wear resistance for repeatable hole-making in demanding machining operations. The drill has a 16 mm cylindrical shank and a 63 mm overall/working length suitable for use in CNC machines and drill presses where stable clamping and accurate concentricity are required.

Advantages

The solid carbide construction ensures high hardness and thermal stability, reducing flank wear and extending tool life compared with HSS alternatives. The 90° point geometry (NC 90 FI) provides reliable centering and good chip evacuation for general-purpose and semi-finishing drilling in a range of wrought and machined metals. A 16 mm shank diameter offers secure mounting in standard chucks and tool holders, supporting consistent runout control during high-speed rotation.

Suitable for

• Precision drilling in steel, stainless steel, cast iron and non-ferrous metals
• CNC machining operations requiring repeatable hole dimensions
• Drill press and production line drilling with rigid clamping
• Semi-finishing and general-purpose holemaking where tool life and accuracy are priorities

Key specifications

• Cutting diameter: 8.00 mm
• Material: solid carbide (VHM)
• Point angle/geometry: NC 90 FI (90°)
• Shank diameter: 16 mm (cylindrical)
• Overall/working length: 63 mm
• Intended use: metalworking / machining

How to use

Mount the drill in a properly rated chuck or tool holder that matches the 16 mm shank and ensure secure clamping to minimise runout. Select appropriate spindle speed and feed rate for the material being machined, taking into account the 8.00 mm diameter and carbide cutting material. Use cutting fluid or coolant for ferrous materials to improve chip evacuation and reduce heat at the cutting edge. Begin drilling with light pecking cycles when appropriate to avoid chip clogging and to maintain dimensional accuracy.

Usage recommendations

For best results, use this solid carbide drill with rigid fixturing and moderate cutting speeds for stainless steels and higher speeds for non-ferrous metals. Regularly inspect the cutting edges for wear and replace the drill when surface finish or hole tolerance degrades.
