Drill bit Art-Pol HSS cylindrical 8 mm AR53980 for metal

The Art-Pol HSS cylindrical drill bit 8 mm AR53980 is a precision metalworking tool designed for drilling holes in a variety of ferrous and non-ferrous metals. Manufactured from high-speed steel (HSS), this 8 mm diameter cylindrical-shank bit offers wear resistance and thermal stability to withstand continuous drilling and moderate heat generation. The shank is made for standard chucks that accept cylindrical bits, making it compatible with most bench and handheld drills used in workshops and repair tasks.

Advantages

The HSS material provides improved hardness and resistance to softening at elevated temperatures compared with carbon steel, ensuring longer tool life during metal drilling. The cylindrical shank simplifies installation in common drill chucks and allows stable rotation with reduced runout when properly secured. The 8 mm diameter is a common size suitable for many fastening and assembly needs, balancing rigidity and material removal rate for efficient hole-making in thin to medium-thickness metal sheets and components.

Suitable for

• Drilling holes in steel and stainless steel (thin to medium thickness)
• Working with aluminum, brass and other non-ferrous metals
• Workshop maintenance, repair and general metal fabrication
• Use in handheld electric drills and bench drill presses with standard chucks

Key specifications

• Diameter: 8 mm
• Material: High-speed steel (HSS)
• Shank type: Cylindrical shank for standard chucks
• Intended use: Metal drilling (ferrous and non-ferrous)
• Typical applications: General-purpose metalworking and repair tasks

How to use

Secure the drill bit in a compatible drill chuck, ensuring the shank is fully inserted and tightened to minimize runout. Select an appropriate cutting speed and feed 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 steel to reduce heat and extend bit life. Clamp the workpiece firmly and start drilling with moderate pressure, maintaining steady axial force and allowing the bit to clear chips periodically.

Usage recommendations

For best results, use a suitable cutting lubricant when drilling ferrous materials, apply correct spindle speed for the metal type, and inspect the bit for wear or chipping before use. Replace the bit if excessive wear reduces drilling accuracy or increases torque demand.
