Drill bit for metal Tvardy 6.0 x 205 mm HSS long DIN1869

Long HSS drill bit Tvardy 6.0 x 205 mm manufactured to DIN 1869 for drilling metal. Made from heat-treated high-speed steel, this drill bit is designed for cutting through steel and other ferrous materials. Its extended length provides reach for through-holes and deeper drilling tasks where a standard-length bit is insufficient. The bit is compatible with hand-held and stationary drills and is supplied in bulk packaging suitable for professional use.

Advantages

The HSS material with heat treatment offers improved hardness and wear resistance, extending tool life when drilling abrasive ferrous materials. The DIN 1869 geometry ensures consistent point angle and flute design for reliable chip evacuation on longer drills. The extended 205 mm overall length gives better access to recessed or deep workpieces while maintaining concentricity and dimensional stability. The bit is suitable for repeated use in workshop and industrial settings due to its robust construction.

Suitable for

• Drilling through steel plates and structural components
• Deep-hole drilling where extra reach is required
• Use in hand-held drills and bench or pillar drills
• General ferrous metal fabrication and repair work

Key specifications

• Material: heat-treated high-speed steel (HSS)
• Diameter: 6.0 mm
• Overall length: 205 mm
• Standard: DIN 1869 geometry
• Intended workpiece: steel and other ferrous metals

How to use

Select a compatible drill chuck and securely clamp the 6.0 mm HSS bit to ensure concentricity. Use appropriate cutting speeds and feed rates for steel to avoid overheating; apply cutting fluid or lubricant for improved cooling and chip evacuation when drilling ferrous materials. For deep-hole drilling, periodically retract the bit to clear chips and maintain a steady, controlled feed. After use, clean and store the bit to prevent corrosion and preserve cutting edges.

Usage recommendations

Use moderate spindle speeds and steady feed when drilling steel, and employ cutting fluid for longer life and better surface finish. When drilling deep holes, withdraw the bit at intervals to remove chips. Ensure the drill is properly aligned and the workpiece securely fixed to reduce runout and extend tool life.
