Spiral drill bit Proline Urbis 22 x 230 mm – 22 mm diameter, 230 mm length

Proline spiral drill bit with a threaded spiral cutting edge, designed for drilling conifers, hardwoods and glued wood materials. The bit has a 22 mm cutting diameter and a total length of 230 mm with a hex shank for secure chucking in compatible drills.

Advantages

The threaded spiral tip improves bite and pull-through for faster hole initiation and reduced walking. The spiral flutes evacuate chips efficiently, helping to maintain cutting speed and reduce clogging. Hex shank ensures a stable, slip-resistant connection in chucks or quick-change adaptors.

Suitable for

• Drilling holes in softwoods (conifers)
• Drilling holes in hardwoods

How to use

Mount the Proline 22 x 230 mm spiral drill bit securely in a compatible drill or quick-change holder using the hex shank. Align the bit with the marked drilling point, start at low speed to engage the threaded tip, then increase speed as the bit cuts through the material. Apply steady, moderate pressure and withdraw periodically to clear chips if drilling deep holes.

Usage recommendations

Use cutting lubricant or reduced speed when drilling very hard or laminated materials to extend bit life. For clean exit holes, support the workpiece underside with sacrificial backing board. Inspect the bit before use and replace if the cutting edge is worn or damaged.
