Drill bit FANAR HSS cylindrical 8 mm — metal drilling, solid HSS material

Cylindrical FANAR HSS drill bit, 8 mm diameter, designed specifically for drilling metal. Made from high-speed steel (HSS), this solid bit offers consistent cutting performance and wear resistance for drilling precise holes in steel and other ferrous materials. The cylindrical shank is compatible with standard chucks used in hand drills and drill presses, making it suitable for general metalworking, maintenance and fabrication tasks that require accurate 8 mm holes.

Advantages

The solid HSS construction provides good hardness and heat resistance during continuous drilling operations, reducing tool wear and maintaining cutting edge stability. The 8 mm diameter ensures repeatable hole sizing while the cylindrical shank allows easy clamping in common drill chucks. The bit’s geometry is optimized for metal cutting, promoting efficient chip evacuation and stable drilling under typical workshop conditions.

Suitable for

• Drilling holes in mild and alloy steels
• Maintenance and repair tasks on metal components
• Fabrication and assembly where precise 8 mm holes are required
• Use in hand drills and drill presses

Key specifications

• Material: Solid high-speed steel (HSS)
• Diameter: 8 mm
• Shank type: Cylindrical shank for standard chucks
• Application: Metal drilling (steel and other ferrous materials)
• Typical use: Manual and machine drilling

How to use

Secure the drill bit firmly in the drill chuck to prevent slippage, ensuring the shank is seated straight. Select an appropriate drilling speed and apply steady, moderate feed pressure; lower speeds and steady coolant or cutting fluid are recommended for harder steels. Clear chips frequently to avoid clogging and overheating. After drilling, withdraw the bit while the spindle is still rotating slowly to help clear chips and maintain hole quality.

Usage recommendations

Use cutting fluid or coolant when drilling thicker or harder steel to extend tool life and improve surface finish. Start with a pilot hole when drilling large-depth holes or when high positional accuracy is required. Inspect the bit regularly for wear or chipping and replace when the cutting edge degrades to maintain hole accuracy and safety.
