Drill bit Art-Pol HSS cylindrical 3 mm for metal, model 53530

Art-Pol HSS cylindrical drill bit 3 mm (model 53530) is a precision metalworking tool designed for drilling clean holes in a variety of metals. Made from high-speed steel (HSS), the 3 mm diameter flute provides stiffness and accuracy for both handheld and bench drilling operations. The cylindrical shank fits standard drill chucks and ensures stable rotation during cutting, while the HSS material delivers improved wear resistance and heat tolerance compared with standard carbon steel bits.

Advantages

The HSS composition provides higher hardness at elevated temperatures, reducing wear during continuous metal drilling. The 3 mm diameter and cylindrical shank ensure compatibility with common chucks and enable precise hole placement in thin and medium-thickness metal sheets. The drill geometry is optimized for general-purpose metal cutting, offering reliable chip evacuation and consistent hole quality. Its compact size and balanced construction make it suitable for repetitive fabrication and maintenance tasks where accuracy is important.

Suitable for

• Drilling holes in steel and iron components
• Piercing non-ferrous metals such as aluminium and copper
• Workshop fabrication and light maintenance work
• Use with handheld drills and bench drill presses

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical shank for standard chucks
• Cutting diameter: 3 mm
• Intended material: ferrous and non-ferrous metals
• Typical applications: metal drilling, fabrication, maintenance

How to use

Secure the drill bit in the drill chuck, ensuring the bit is centered and tightened to prevent wobble. Select an appropriate cutting speed 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 thicker or harder metals to reduce heat buildup and extend bit life. Apply steady, even pressure and allow the bit to cut without forcing; clear chips periodically to maintain cutting efficiency.

Usage recommendations

For best results, pre-center holes with a punch when drilling sheet metal to prevent bit walking. When drilling hardened steels or performing prolonged drilling operations, use coolant and reduce speed to preserve the cutting edge. Store the bit in a dry, organized holder to avoid damage and corrosion.
