Drill bit Art-Pol HSS cylindrical 12 mm AR53820 for metal

Art-Pol HSS cylindrical drill bit 12 mm (AR53820) is engineered for drilling metal in workshop and industrial environments. Manufactured from high-speed steel (HSS), this 12 mm drill bit provides wear resistance and improved heat tolerance during continuous drilling operations. Its cylindrical shank fits standard drill chucks and is suitable for creating through holes and pilot holes in a range of ferrous and non-ferrous metals.

Advantages

The high-speed steel construction offers a balance of hardness and toughness, increasing resistance to wear and softening at elevated temperatures. The cylindrical shank ensures compatibility with most drill chucks for secure clamping and straightforward tool changes. The 12 mm diameter provides a common size for general metalworking tasks, allowing consistent hole dimensions and reliable performance across different metal types.

Suitable for

• Drilling steel and iron sheets and plates
• Creating pilot and through holes in non-ferrous metals such as aluminum and brass
• General workshop and fabrication tasks requiring a 12 mm hole
• Use with handheld and bench drills that accept cylindrical shanks

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical
• Nominal diameter: 12 mm
• Intended application: metal drilling (ferrous and non-ferrous)
• Hole types: through holes and pilot holes

How to use

Select an appropriate drill speed and use cutting fluid when drilling thicker or harder metals to reduce heat and extend tool life. Secure the workpiece with clamps or a vise to prevent movement. Insert the cylindrical shank into the drill chuck and tighten firmly. Start drilling with light pressure to establish the hole, then apply steady pressure while maintaining alignment. Withdraw the drill occasionally to clear chips and reapply coolant as needed.

Usage recommendations

For best results, match drill speed to the metal being drilled (lower speeds for harder steels, higher speeds for softer non-ferrous metals) and use appropriate cutting fluid. Regularly inspect the cutting edges and replace the bit when wear or chipping reduces drilling accuracy.
