Drill bit FANAR HSS straight shank for metal 7.9 mm W2-101811-0790

FANAR HSS straight shank drill bit for metal, diameter 7.9 mm, is a solid high-speed steel cutting tool designed for drilling ferrous and non-ferrous metals. The cylindrical (straight) shank fits chucks on hand drills and drill presses that accept straight shanks. This 7.9 mm HSS drill is intended for through holes and hole-starting operations in workshop metalworking, maintenance and fabrication tasks where a robust, wear-resistant bit is required for repetitive metal drilling.

Advantages

The high-speed steel (HSS) construction provides good heat resistance and wear characteristics for machining a range of metals. The straight shank design ensures compatibility with common drill chucks and simplifies bit changes. Precision ground flutes and a controlled point geometry deliver reliable cutting performance and effective chip evacuation during drilling. The solid one-piece construction reduces the risk of breakage under standard operating conditions and supports consistent hole quality.

Suitable for

• Drilling through mild steel, stainless steel, aluminium and other non-ferrous metals
• Workshop fabrications and mechanical maintenance
• Use with hand-held drills and drill presses with straight chucks
• Starting holes for tapping or reaming operations

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Straight / cylindrical shank
• Diameter: 7.9 mm
• Tip style: Standard twist drill geometry for metal
• Length: suitable for common drill chuck capacities (standard overall length for 7.9 mm metal drills)

How to use

Secure the drill bit in the chuck so that the straight shank is seated firmly and concentric. Select an appropriate spindle speed for the metal being drilled—lower speeds for harder steels, higher speeds for aluminium—and use cutting fluid to reduce heat and improve chip evacuation when drilling ferrous materials. Begin with a center punch for accurate hole positioning if needed, apply steady feed pressure, and clear chips periodically for deep holes. After use, clean the bit and store it dry to minimise corrosion.

Usage recommendations

For longer tool life and improved hole accuracy, use appropriate cutting fluid, maintain correct spindle speeds and feeds for the material, and avoid excessive lateral force. When drilling stainless steels or hardened materials, reduce speed and increase coolant application. Inspect the drill for wear or damage before repeated use and resharpen as necessary to restore cutting performance.
