Drill bit Art-Pol HSS cylindrical 12 mm for metal, model 53120

Art-Pol HSS cylindrical drill bit 12 mm (model 53120) is designed for drilling metal and provides a reliable cutting edge for workshop and maintenance tasks. Manufactured from high-speed steel (HSS), the bit offers improved wear resistance and heat tolerance compared with standard carbon-steel drills. Its cylindrical shank fits common chucks used in hand drills and drill presses, enabling straightforward mounting and stable operation when creating holes in steel, iron and non-ferrous metals.

Advantages

The HSS material ensures durability and consistent cutting performance under elevated temperatures encountered during metal drilling. The 12 mm diameter provides a balance between material removal rate and precision for typical metalworking applications. A cylindrical shank makes the bit compatible with a wide range of drill chucks without requiring special adapters, while the ground cutting edges deliver clean holes with reduced burrs when used at appropriate speeds and with suitable lubrication.

Suitable for

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

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 12 mm
• Shank type: cylindrical
• Intended use: metal drilling (ferrous and non-ferrous)
• Suitable for use in hand drills and drill presses

How to use

Secure the workpiece and mark the drilling point before starting. Mount the 12 mm HSS drill bit in the chuck and tighten firmly. Select an appropriate spindle speed for the material being drilled: lower speeds for harder steels and higher speeds for softer non-ferrous metals. Apply steady, moderate feed pressure and use cutting fluid or lubrication to reduce heat and extend tool life. Withdraw the bit occasionally to clear chips when drilling deeper holes, then resume until the hole is complete.

Usage recommendations

For best results, use cutting lubricant and clamp the workpiece securely. Match drill speed to the material: slower for hardened steels, faster for aluminum. Replace the bit when wear or chipped edges affect hole quality to maintain clean, accurate holes.
