Drill bit Proline 14 x 230 mm spiral twist drill for metal and wood

Spiral drill Proline 14 x 230 mm is a twist drill with a threaded spiral blade designed for drilling softwood, hardwood and glued wood components. It features a hex shank for secure chuck engagement and consistent drilling performance in both metal and wood applications where a long-reach, aggressive cutting action is required.

Advantages

The threaded spiral tip pulls the drill into the material for faster penetration and reduced walking. The spiral flute efficiently evacuates chips, improving hole quality. The hex shank provides slip-resistant attachment to impact drivers and chucks with hex adapters. The 14 x 230 mm dimensions give extended reach for deeper holes while maintaining rigidity.

Suitable for (tasks / use cases)

• Drilling holes in softwood and coniferous timber
• Drilling hardwood and laminated timber panels
• Create deep pilot holes for screws or dowels in carpentry
• General woodworking tasks requiring long-reach holes

How to use

Mount the drill securely in a compatible chuck or hex holder. Align the drill perpendicular to the workpiece, start at low speed to engage the threaded tip, then increase speed as the bit pulls into the material. Apply steady axial pressure without forcing; allow the spiral flute to clear chips periodically. After drilling, withdraw the bit while the drill is still rotating to help clear debris.

Usage recommendations

Use appropriate drill speeds for the material: lower speeds for hardwoods and higher speeds for softwoods. Keep the bit sharp and clean for best results. Wear eye protection and follow standard workshop safety practices when drilling.
