## Long description

Long HSS metal drill bit Tvardy, size 8.0 x 390 mm, manufactured to DIN1869 for drilling metal. This high-speed steel (HSS) twist drill is designed for through-drilling and deep-hole applications where extended reach is required. The geometry and material of the bit provide heat resistance and wear performance suitable for standard metalworking tasks when used with appropriate speeds and lubrication.
Advantages
The HSS construction offers good toughness and thermal stability for cutting into a range of ferrous and non-ferrous metals. The long length allows access to recessed or deep features without the need for extensions. Manufactured to DIN1869 dimensions, the drill bit maintains consistent geometry for reliable chip evacuation and concentricity in both handheld drills and drill presses. The tool is suitable for repeated drilling operations with standard cooling or cutting fluids to prolong life.
Suitable for
Through-drilling of steel, cast iron and non-ferrous metals
Deep-hole drilling where extended reach is necessary
Use in drill presses and hand-held drills with appropriate chucks
Workshop maintenance, metal fabrication and mechanical repairs
Key specifications
Material: High-speed steel (HSS)
Diameter: 8.0 mm
Total length: 390 mm
Shank type: cylindrical suitable for standard chucks
Standard: manufactured to DIN1869 dimensional and geometry requirements
How to use
Secure the drill bit in a properly rated chuck or collet, ensuring concentric clamping and sufficient grip length on the shank. Select cutting speed and feed appropriate for the workpiece material and bit diameter; reduce speed when drilling harder steels. Use cutting fluid or coolant for metal drilling to reduce heat, improve chip evacuation and extend tool life. For deep-hole drilling, withdraw periodically to clear chips and allow cooling.
Usage recommendations
Inspect the drill bit for wear or damage before use. Match the drill speed and lubrication to the specific metal being drilled, and ensure proper fixturing to prevent deflection when using the long 390 mm length.
