Drill bit Proline Urbis Spiral 40 x 460 mm, spiral shank, general-purpose

Urbis Proline Spiral 40 x 460 mm is a general-purpose drill bit designed for boring into softwoods, hardwoods and glued workpieces. The bit features a threaded spiral cutting edge and a hex shank for secure attachment in chucks and quick-change systems.

Advantages

The threaded spiral tip pulls the bit into the material for efficient, controlled drilling while the spiral flutes remove chips to maintain a clean hole. The hex shank ensures a stable grip and reduces slippage in standard drills and impact drivers. The 40 x 460 mm dimensions provide a long reach for deep holes and through drilling in timber elements.

Suitable for

• Boring holes in softwood (coniferous timber)
• Boring holes in hardwood
• Drilling laminated and glued wooden workpieces
• Deep or through-holes in construction timber and carpentry

How to use

Secure the hex shank of the drill bit in a compatible drill chuck or quick-change adapter. Start drilling at a low speed to engage the threaded tip and allow the bit to self-feed into the material, then increase speed as appropriate for the wood type. Apply steady axial pressure and clear chips periodically if necessary. For through-holes, ensure support under the workpiece to prevent splintering on the exit side.

Usage recommendations

Use appropriate cutting speed and moderate pressure for hardwood to avoid overheating. For clean exit holes, back the bit out slowly or support the workpiece. Inspect the bit before use and replace if the cutting edge is worn or damaged.
