Drill bit FANAR NAWIERTAK NC FI 6.00 90° HSSE TiN

FANAR NAWIERTAK NC FI 6.00 90° HSSE TiN is a precision 6.00 mm diameter drill bit engineered for accurate through and spot drilling in metalworking applications. Constructed from high-speed steel with added cobalt (HSSE) and finished with a titanium nitride (TiN) coating, the tool is intended to deliver improved wear resistance and extended service life compared with uncoated HSS drills. The 90° point geometry supports reliable centring and chip formation for consistent hole quality in a variety of ferrous and non-ferrous materials.

Advantages

The HSSE substrate provides enhanced hardness and heat resistance for demanding machining conditions, and the TiN coating reduces friction and surface wear during cutting. The 90° point ensures accurate positioning and reduces walking, while the 6.00 mm diameter is suitable for common precision holes. Overall, the combination of material, geometry and coating contributes to longer tool life, stable hole tolerance and reduced frequency of tool change in production environments.

Suitable for

• Precision drilling in steel and cast iron
• Machining centre and CNC drilling operations
• Spot drilling and start holes before reaming or tapping
• Short- to medium-length production runs requiring consistent hole quality

Key specifications

• Diameter: 6.00 mm
• Point angle: 90°
• Material: high-speed steel with cobalt (HSSE)
• Coating: titanium nitride (TiN)
• Intended use: metalworking/drilling

How to use

Secure the drill bit in a properly rated drill chuck or tool holder and set spindle speed according to the workpiece material and machine capabilities. Use appropriate cutting fluid or coolant to manage heat and improve chip evacuation when drilling metals. Apply steady feed pressure without excessive force to maintain concentricity and prevent premature wear. Inspect holes for tolerance and surface finish, and replace the bit when wear adversely affects hole quality.

Usage recommendations

For best results, select cutting speeds and feed rates suitable for HSSE tools and use cutting fluid when machining most steels; avoid dry drilling in high-temperature or abrasive conditions to preserve the TiN coating and substrate hardness.
