Drill bit Art-Pol HSS cylindrical 4 mm AR53740 for metal

Art-Pol HSS cylindrical drill bit, 4 mm diameter (model AR53740), is engineered for drilling metal with precision. Manufactured from high-speed steel (HSS), this 4 mm drill bit provides wear resistance and increased heat tolerance required for metalworking tasks. The cylindrical shank allows secure clamping in hand drills and drill presses, enabling clean, consistent holes in steel, iron and non-ferrous metals in workshop and maintenance environments.

Advantages

The HSS material offers a balance of hardness and toughness that helps resist wear and maintain cutting performance at elevated temperatures. The 4 mm cutting diameter produces small, accurate holes suitable for mechanical assemblies and repair work. A straight cylindrical shank ensures compatibility with common chucks and provides stable concentric rotation during drilling. The ground geometry of the tip promotes efficient chip removal and reduces unnecessary heat buildup.

Suitable for

• Drilling holes in steel and iron components
• Working with non-ferrous metals such as aluminum and brass
• General maintenance and workshop drilling tasks
• Use with hand drills and drill presses for small-diameter holes

Key specifications

• Material: high-speed steel (HSS)
• Cutting diameter: 4 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Intended use: metal drilling (ferrous and non-ferrous)
• Geometry: ground tip for chip evacuation and efficient cutting

How to use

Secure the drill bit in the chuck ensuring the shank sits fully and is tightened to prevent slipping. Select a drill speed appropriate for the metal being worked — lower speeds for harder steels, higher speeds for softer non-ferrous metals — and apply steady, moderate pressure. Use cutting fluid or lubricant when drilling ferrous metals to reduce heat and extend tool life. Back the bit out periodically to clear chips when drilling deeper holes.

Usage recommendations

For best results, match drilling speed and feed to the workpiece material, maintain proper lubrication when cutting ferrous metals, and replace the bit when wear or loss of sharpness begins to affect hole quality.
