Drill bit FANAR HSS cylindrical 8.6 mm for metal, model W2-101811-0860

Cylindrical HSS drill bit FANAR, 8.6 mm diameter, designed for drilling metal. Made from high-speed steel (HSS) to maintain cutting edge and resist wear at elevated temperatures. The cylindrical shank fits standard chucks and is suitable for general metalworking tasks including fabrication, maintenance and repair where precision holes in steel, iron and non‑ferrous metals are required.

Advantages

The FANAR HSS drill bit provides consistent drilling performance on a range of metals due to its high-speed steel construction, which preserves hardness during high-temperature cutting. Its 8.6 mm diameter offers a precise bore size for medium-duty metalwork, while the cylindrical shank ensures compatibility with common drill chucks and holders. The geometry of the flutes promotes efficient chip removal and stable drilling, reducing the likelihood of workpiece damage when used with appropriate feeds and speeds.

Suitable for

• Drilling through steel and cast iron
• Holes in non-ferrous metals such as aluminum and brass
• General fabrication and assembly work
• Maintenance, repair and workshop tasks

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 8.6 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Intended use: drilling metal (ferrous and non‑ferrous)
• Flute design: two-flute geometry for chip evacuation and stable cutting

How to use

Secure the drill bit in a compatible chuck and ensure it is tightly clamped to avoid runout. Select an appropriate spindle speed and feed rate for the metal being drilled; lower speeds for harder steels and higher speeds for softer, non‑ferrous metals. Use cutting fluid or lubricant when drilling ferrous materials to reduce heat and prolong tool life. Start with a center punch or pilot mark to prevent wandering, and apply steady, even pressure while drilling. Clear chips periodically to maintain cutting efficiency.

Usage recommendations

For best results, match drill speed and feed to workpiece material and thickness, use appropriate coolant or cutting fluid when machining steel, and check for tool wear regularly. When drilling deeper holes, peck drilling or intermittent retraction helps to evacuate chips and control temperature.
