Drill bit FANAR HSS cylindrical 8.5 mm for metal, model W2-101811-0850

Solid HSS cylindrical drill bit FANAR 8.5 mm is designed for drilling metal and producing clean through-holes in steel and a variety of ferrous and non-ferrous metals. Made from high-speed steel, the bit provides a balance of hardness and toughness suitable for workshop, maintenance and fabrication tasks. The cylindrical shank allows secure clamping in standard drill chucks and drill presses, making it compatible with both handheld and stationary drilling equipment.

Advantages

The HSS material offers good wear resistance and heat tolerance during medium-speed drilling of metal. The cylindrical shank ensures stable clamping and straightforward replacement in chucks. The nominal 8.5 mm diameter gives a precise hole size for through-holes and fitting fasteners, while the solid construction reduces the risk of breakage under normal operating conditions. The bit is suitable for repeated use in general metalworking operations.

Suitable for

• Drilling through steel, stainless steel and other ferrous metals
• Creating holes in aluminum and other non-ferrous metals
• Workshop maintenance and repair tasks
• Fabrication and assembly where standard-size through-holes are required

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Nominal diameter: 8.5 mm
• Application: Through-holes in ferrous and non-ferrous metals
• Compatibility: Standard drill chucks and drill presses

How to use

Secure the drill bit in the chuck of a drill press or hand drill, ensuring the cylindrical shank is clamped evenly and the bit is centered. Use appropriate cutting speed and feed for the workpiece material and apply cutting fluid when drilling harder metals to reduce heat and extend bit life. Start with a steady, controlled feed and avoid excessive side pressure. Withdraw the bit periodically to clear chips and prevent clogging when drilling deep holes.

Usage recommendations

For best results, select drill speeds and feeds according to the metal being drilled: lower speeds for stainless steel, moderate speeds for carbon steel, and higher speeds for aluminum. Use a suitable cutting lubricant for steels and periodically clear chips to maintain efficient cutting. Inspect the bit for wear and replace if the cutting edges become dull or chipped to maintain hole quality and safety.
