Drill bit FANAR HSS cylindrical 4.1 mm – metal drilling, model W2-101811-0410

FANAR HSS cylindrical drill bit with a 4.1 mm diameter is designed for drilling metal in general metalworking applications. Manufactured from high-speed steel (HSS), the bit combines hardness and heat resistance for cutting through ferrous and non-ferrous metals. The cylindrical shank fits standard chucks, making it suitable for use in hand drills and drill presses for tasks that require precise, straight holes in metal components.

Advantages

The HSS material provides elevated hardness and temperature resistance during continuous drilling, reducing wear and maintaining cutting performance. The 4.1 mm diameter offers a balance between precision and material removal rate for common metalworking needs. The cylindrical shank ensures reliable clamping in standard chucks and straightforward replacement when changing bits.

Suitable for

• Drilling holes in steel, stainless steel and cast iron (pre-drilling and light finishing)
• Working with non-ferrous metals such as aluminium, brass and copper
• Use in hand-held drills and drill presses for maintenance and fabrication tasks
• General workshop metalworking, repair and assembly operations

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 4.1 mm
• Shank type: Cylindrical shank for standard chucks
• Primary application: Metal drilling (ferrous and non-ferrous)
• Intended tools: Hand drills and drill presses

How to use

Select an appropriate cutting speed for the metal being drilled and secure the workpiece to prevent rotation. Mount the drill bit into the drill chuck, ensuring it is seated straight and tightened. Use steady pressure and a consistent feed rate; for harder materials reduce speed and increase coolant or intermittent pecking to clear chips. After drilling, remove burrs and inspect the hole for correct diameter and finish.

Usage recommendations

For extended tool life when drilling harder steels, use cutting fluid or coolant and moderate spindle speeds. When drilling thin sheets, support the material to avoid deformation and consider backing to reduce burrs. Regularly inspect the bit for wear and regrind or replace when the cutting edges become dull to maintain hole quality.
