Drill bit Proline 90516, metal, Ø 5 mm, length 160 mm, 1 pc

Single Proline 90516 metal drill bit with a 5 mm diameter and 160 mm overall length. Designed for drilling metal, this straight flute bit is supplied as one piece and suits workshop and maintenance tasks requiring precise through-holes or pilot holes in steel and other ferrous materials. The drill is intended for industrial and professional applications and features a geometry that promotes centered drilling and consistent hole quality.

Advantages

The Proline 90516 offers a 5 mm diameter and a 160 mm overall length that enable access to deeper workpieces while maintaining rigidity. Its construction provides improved durability and accurate centered drilling for repeatable results. The straight-flute design reduces lateral deflection during cutting and the single-piece supply simplifies tool selection for individual tasks.

Suitable for

• Drilling through-holes and pilot holes in steel and other ferrous metals
• Workshop and maintenance operations requiring precise, repeatable holes
• Industrial and professional drilling applications where a longer reach is needed

Key specifications

• Material application: metal / ferrous materials
• Diameter: 5 mm
• Overall length: 160 mm
• Flute type: straight flute
• Pack quantity: 1 piece

How to use

Secure the workpiece and select an appropriate cutting speed and feed for the metal being drilled. Clamp the Proline 90516 drill bit firmly in the chuck, ensuring concentric alignment. Begin drilling at low speed to establish a centered entry, then increase speed and apply steady, even pressure. Use cutting fluid where appropriate to reduce heat and extend tool life. Back out periodically to clear chips when drilling deep holes.

Usage recommendations

For best results when drilling steel or other ferrous metals, use an appropriate cutting lubricant, maintain correct spindle speeds for a 5 mm carbide-tipped or high-speed drill, and ensure the drill is held rigidly in a well-aligned chuck or tool holder. Inspect the drill for wear before use and replace when cutting performance degrades.
