Drill bit Proline 12 x 230 mm — Spiral drill bit for metal and wood

Proline spiral drill bit 12 x 230 mm is a threaded spiral wood bit designed for drilling through softwoods, hardwoods and laminated boards. It features a hex shank for secure fitting in chucks and quick bit changes, suitable for handheld and stationary drills.

Advantages

The spiral threaded geometry ensures efficient chip removal and faster feed into the workpiece while maintaining clean holes. A hexagonal shank provides stable torque transfer and reduces slippage in the drill chuck. The 230 mm overall length allows for deep drilling in timbers and laminated panels.

Suitable for

• Drilling holes in softwood and coniferous timber
• Drilling in hardwood and dense timber
• Working with laminated boards and glued assemblies
• Use with handheld drills and drill presses

How to use

Install the Proline 12 x 230 mm spiral drill bit into a compatible drill chuck, ensuring the hex shank is fully seated. For best results, start drilling at low speed to position the bit, then apply steady feed; the threaded tip will pull the bit into the material. Clear chips regularly during deep holes to prevent clogging and overheating. When drilling laminated or glued materials, support the workpiece to reduce splintering at the exit side.

Usage recommendations

Use appropriate drilling speeds for the material (lower speeds for hardwoods), maintain steady pressure without forcing the bit, and wear eye protection. Inspect the bit for wear before use and replace if the cutting edges are dull or damaged.
