Drill bit Art-Pol HSS cylindrical 3 mm for metal, model 53330

Art-Pol HSS cylindrical drill bit, 3 mm diameter, designed for drilling metal. Manufactured from high-speed steel (HSS) to provide wear resistance and maintain cutting performance under elevated temperatures typical of metalworking. The cylindrical shank fits standard chucks on handheld drills and drill presses, enabling precise drilling of through-holes and pilot holes in steel, iron and other ferrous materials encountered in workshop, repair and maintenance tasks.

Advantages

The HSS material ensures improved hardness and heat resistance compared with carbon steel bits, which reduces premature wear during extended use. The 3 mm diameter provides good control for small-diameter holes and pilot drilling; the cylindrical shank enables secure clamping in standard drill chucks. The geometry and finish are optimised for clean chip evacuation and consistent hole accuracy when used at appropriate speeds and with correct lubrication.

Suitable for

• Drilling through-holes in steel plates and sections
• Creating pilot holes for tapping or larger drills
• Maintenance and repair tasks in workshops and industrial settings
• Use with handheld electric drills and drill presses

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 3 mm
• Shank type: Cylindrical shank for standard chucks
• Intended material: Metal, primarily ferrous metals (steel, iron)
• Typical use: Through-holes and pilot holes

How to use

Secure the drill bit in the chuck ensuring the shank is fully seated and tightened. Select an appropriate rotational speed for 3 mm HSS drilling in metal (moderate to high speed depending on material hardness) and use cutting fluid or lubricant to reduce heat and improve chip evacuation. Apply steady, even feed pressure; withdraw periodically on deep holes to clear chips. After use, clean the bit and store in a dry place to prevent corrosion.

Usage recommendations

For best results when drilling steel and iron, use a suitable cutting lubricant and moderate speeds to extend tool life. When starting holes in thin or irregular surfaces, consider using a centre punch to prevent wandering. Replace the bit if the cutting edges show excessive wear or chipping to maintain hole quality and reduce load on the drill.
