## Long description

GRAPHITE 8 mm titanium-coated drill bit with a straight (cylindrical) shank is designed for drilling steel and other metals. The titanium coating reduces wear and helps dissipate heat during operation, extending tool life under normal working conditions. The straight shank fits into standard 8 mm chucks on hand drills and drill presses, making this drill bit suitable for general metalworking, repair and maintenance tasks.
Advantages
The titanium coating provides improved surface hardness and thermal stability compared with uncoated bits, resulting in slower wear and more consistent cutting performance. The 8 mm diameter offers a balance between rigidity and material removal rate for common metalworking operations. The straight shank ensures secure clamping in standard chucks, while the selected geometry of the tip aids in centring and initial penetration in metal surfaces.
Suitable for
 Drilling holes in steel and non-ferrous metals
 General repair and maintenance tasks
 Use with hand drills and drill presses that accept 8 mm straight shanks
 Workshops and professional or hobby metalworking projects
Key specifications
 Diameter: 8 mm
 Shank type: straight (cylindrical)
 Coating: titanium (wear-resistant surface finish)
 Intended material: steel and other metals
 Compatible with standard 8 mm chucks
How to use
Select an appropriate cutting speed and feed rate for the material being drilled; lower speeds are generally recommended for harder steels. Secure the workpiece firmly and use a center punch to prevent wandering when starting the hole. Clamp the straight shank in the drill chuck ensuring proper alignment and firm grip. Use cutting fluid or coolant when drilling metal to reduce heat and improve cutting performance, withdraw the bit occasionally to clear chips, and allow the bit to cool periodically during extended use.
Usage recommendations
For best results, match drill speed and feed to the workpiece material, apply suitable cutting fluid, and avoid excessive side loads. Inspect the cutting edges periodically and replace the bit when wear or chipping degrades performance. Store the bit in a dry place to protect the coating.
