Drill bit Art-Pol HSS cylindrical 8 mm AR53780 for metal

Art-Pol HSS cylindrical drill bit with an 8 mm diameter (model AR53780) is designed for drilling metal. Manufactured from high-speed steel (HSS), this drill bit offers wear resistance and improved heat tolerance for typical metalworking tasks. It is suited for both manual and machine drilling and produces precise through-holes in steel, cast iron and non-ferrous metals, making it a practical choice for workshops, maintenance and production environments.

Advantages

The high-speed steel construction delivers consistent hardness and maintains cutting performance at elevated temperatures, reducing tool wear during extended drilling sessions. The cylindrical shank ensures compatibility with standard chucks and collets, providing secure clamping and straight drilling. Ground flutes and a sharpened tip geometry promote efficient chip evacuation and accurate centering, helping to produce clean, dimensional holes in a range of metal materials.

Suitable for

• Drilling through-holes in mild and alloy steels
• Drilling cast iron components
• Machining non-ferrous metals such as aluminium and brass
• Workshop repairs and maintenance operations
• Production runs requiring repeatable, precise holes

Key specifications

• Drill type: Twist drill for metalworking
• Material: High-speed steel (HSS)
• Shank style: Cylindrical shank for standard chucks/collets
• Diameter: 8 mm
• Suitable materials: Steel, cast iron, aluminium, brass and other non-ferrous metals
• Typical applications: Manual drilling and machine drilling (bench drill, drill press, portable drill)

How to use

Secure the drill bit in a compatible chuck or collet with sufficient clamping length on the cylindrical shank. Select an appropriate spindle speed and feed rate for the material being drilled—lower speeds for harder steels, higher for softer non-ferrous metals. Apply cutting fluid or coolant when drilling steel or cast iron to reduce friction and extend tool life. Begin drilling with steady pressure, keeping the drill aligned to the workpiece to avoid wandering; withdraw periodically to clear chips if necessary. After completing the hole, deburr edges as required.

Рекомендации по использованию

Use appropriate personal protective equipment (safety glasses, gloves) and clamp the workpiece securely. For best results, pre-center or use a pilot hole on large or deep holes. Regularly inspect the cutting edge and regrind or replace the bit when wear impairs cutting performance.
