Drill bit Proline 58539 — 1 pc, standard twist drill for metal and wood

Proline 58539 is a single standard twist drill bit supplied as one piece, designed for general-purpose drilling in metal and wood. The bit features conventional 118° point geometry and a straight flute profile suitable for through-holes and preparatory drilling. It is intended for use with handheld drills and drill presses where a single-size bit is required for routine workshop and DIY tasks.

Advantages

The twist drill offers a straightforward design that balances cutting performance and ease of use. Its standard point angle ensures reliable centering and chip formation in common ferrous and non-ferrous metals as well as wood. Supplied as a single unit, the bit is easy to store and replace, and its geometry is compatible with common drill chucks and collets.

Suitable for

• Drilling through-holes in sheet metal and plate
• Creating holes in soft and hardwoods for assembly or joinery
• General workshop and DIY maintenance tasks
• Use in handheld electric drills and drill presses

Key specifications

• Flute: straight flute for chip evacuation during through-drilling
• Supply quantity: 1 piece

How to use

Secure the drill bit in a suitable chuck or collet, ensuring it is held concentrically. Select an appropriate spindle speed for the material—slower speeds for harder metals, higher speeds for softer metals and wood. Apply steady, even pressure and clear chips periodically to avoid clogging. For metal drilling, use cutting fluid or lubricant as required; for wood, remove chips to prevent burning. When a precise hole diameter is required, consider using a pilot or step drilling sequence.

Usage recommendations

For best results, match drill speed and feed to the work material, use appropriate lubrication when drilling metal, and inspect the bit for wear before use. Store the single-piece drill in a protective case or rack to prevent edge damage and ensure consistent drilling performance.
