Drill bit Art-Pol HSS cylindrical 9 mm for metal, model 53090

Art-Pol HSS cylindrical drill bit 9 mm (model 53090) is engineered for reliable metal drilling. Manufactured from high-speed steel (HSS), the 9 mm diameter bit is designed to produce accurate round holes in steel, cast iron and non-ferrous metals. The cylindrical shank fits standard drill chucks and is suitable for hand-held drills and drill presses used in workshops, maintenance and fabrication environments.

Advantages

The HSS material provides elevated wear resistance and good heat tolerance during continuous drilling, reducing the risk of premature dulling. The cylindrical shank ensures secure clamping in conventional chucks while the precisely ground point improves centring and hole quality. The simple geometry supports a balance between cutting efficiency and tool life when used with appropriate speed and lubrication.

Suitable for

• Drilling holes in steel and iron
• Working with non-ferrous metals such as aluminum and brass
• General workshop and maintenance drilling tasks
• Fabrication tasks requiring 9 mm through-holes

Key specifications

• Material: high-speed steel (HSS)
• Tip type: standard twisted point for metal
• Shank type: cylindrical (straight) shank compatible with standard chucks
• Diameter: 9 mm
• Intended materials: steel, cast iron, non-ferrous metals

How to use

Secure the drill bit in the drill chuck ensuring the shank is fully clamped. Select an appropriate drilling speed for the material—lower speeds for harder steels and higher speeds for softer non-ferrous metals. Mark and centre the drilling location; for greater accuracy use a centre punch before drilling. Apply steady pressure without forcing the bit and back off periodically to clear chips. Use cutting fluid or lubricant when drilling harder steels to reduce heat and prolong tool life. After completing the hole, withdraw the bit while the drill is still rotating to help clear debris.

Usage recommendations

For consistent results, match drill speed and lubrication to the workpiece material, maintain a sharp cutting edge, and clamp workpieces securely. Replace the bit when wear affects hole accuracy or cutting performance.
