Drill bit Artu cylindrical titanium-coated for metal 8 mm (model 16708)

Artu cylindrical titanium-coated drill bit for metal, 8 mm diameter (model 16708), is designed for drilling holes in steel and a variety of other metals. The titanium coating increases surface hardness and improves heat dissipation during cutting, extending tool life compared with uncoated HSS bits. The straight shank fits standard chucks of handheld drills and bench drill presses, making this 8 mm bit a practical choice for both workshop and industrial environments where standard-diameter metal holes are required.

Advantages

The titanium coating reduces friction and wear, which helps maintain cutting performance and prolongs the service life of the drill bit. Its 8 mm cylindrical shank provides stable clamping in standard chucks, while the ground cutting edges offer consistent hole quality and faster penetration in a range of ferrous and non-ferrous metals. The bit is suitable for repeated use in production or repair tasks and is compatible with common drilling speeds used for metalworking.

Suitable for

• Drilling through steel plates and profile sections
• Creating holes in aluminum, brass and other non-ferrous metals
• Workshop repair and maintenance tasks
• Handheld drill and drill press applications
• General metal fabrication and assembly work

Key specifications

• Diameter: 8 mm
• Shank type: cylindrical (straight) shank compatible with standard chucks
• Coating: titanium (Ti) surface treatment for improved wear resistance and heat dissipation
• Material: high-speed steel cutting core with surface coating
• Recommended material use: ferrous and non-ferrous metals

How to use

Secure the 8 mm drill bit in the drill chuck ensuring the shank is clamped firmly and runout is minimized. Use appropriate cutting fluid when drilling steel to reduce heat and improve chip evacuation. Select a drilling speed suitable for the workpiece material and thickness; start with moderate speed and apply steady feed pressure. Remove chips frequently from deep holes to prevent clogging and overheating. After use, clean any residues and store the bit in a dry place to preserve the coating.

Usage recommendations

For best results when drilling metals, use cutting fluid, moderate spindle speeds, and steady feed pressure. Avoid excessive lateral loads that can cause chipping or premature wear of the titanium coating. Inspect the cutting edges regularly and replace the bit when signs of significant wear or dullness appear.
