Drill bit Proline 70816, metal, Ø 8 mm, length 160 mm, 1 pc

Proline 70816 is a single metal drill bit with an 8 mm diameter and 160 mm overall length, designed for drilling metal in workshop and construction environments. Intended for creating through-holes and pilot holes in steel and other ferrous materials, this drill bit is compatible with handheld drills and drill presses and supplied as one piece. The bit’s geometry and length make it suitable for a range of repair, fabrication and installation tasks where precise metal penetration is required.

Advantages

The Proline 70816 drill bit provides consistent hole diameter and straightness over its 160 mm length, enabling accurate drilling in metal sheets, plates and structural components. Its design supports clean chip evacuation for reduced clogging and stable cutting action during prolonged use. Supplied as a single, ready-to-use unit, the bit fits standard drill chucks and is suitable for both portable and bench-mounted drilling equipment.

Suitable for

• Drilling through-holes and pilot holes in steel and ferrous metals
• Workshop metal fabrication and repair tasks
• Installation of fasteners where precise hole diameter is required
• Use with handheld drills and drill presses

Key specifications

• Material application: metal (ferrous materials)
• Diameter: 8 mm
• Overall length: 160 mm
• Quantity: 1 piece
• Intended use: through-holes and pilot holes

How to use

Secure the drill bit in the chuck of a handheld drill or drill press, ensuring proper clamping and alignment. Select an appropriate spindle speed and apply steady pressure to begin drilling; reduce speed for harder steels and increase cooling or lubrication where needed. Withdraw periodically to clear chips and prevent overheating. After completing the hole, clean the bit and store it dry to maintain cutting performance.

Usage recommendations

Use cutting fluid or lubricant when drilling hardened or thick steel to extend tool life and improve chip evacuation. Match drill speed and feed to the material thickness and hardness, and always wear appropriate eye and hand protection when drilling metal.
