Drill bit Proxxon 23402, length 600 mm, single piece

Proxxon 23402 is a single 600 mm drill bit designed for extended-reach drilling where standard-length bits are insufficient. Manufactured for use with compatible drills and chucks, this long bit provides access to deep or hard-to-reach holes while maintaining the precision required for metalworking, carpentry, and maintenance tasks. The product is supplied as one piece and is intended for users who need a reliable tool for drilling at depth without repeatedly changing extensions.

Advantages

The 600 mm length enables drilling into deep cavities and through thick materials without additional extensions. Its single-piece construction reduces runout and wobble compared with multi-part extension systems, improving hole accuracy. The design is compatible with standard drill chucks, allowing straightforward installation and removal. Being a long, dedicated drill bit simplifies workflow for jobs that require repeated deep drilling, reducing setup time.

Suitable for

• Deep or hard-to-reach hole drilling in metal
• Drilling through thick timber and composite materials
• Maintenance and repair tasks in confined spaces
• Precision drilling where extended reach is required

Key specifications

• Overall length: 600 mm
• Sold as: single piece
• Compatibility: fits standard drill chucks
• Intended use: extended-reach precision drilling

How to use

Secure the drill bit in a compatible drill chuck, ensuring the shank is clamped firmly and runout is minimal. Select an appropriate drill speed and apply steady feeding pressure suitable for the material being drilled. Use cutting lubricant when drilling metals to extend tool life and improve chip evacuation. After use, clean the flute and shank and store the bit in a dry place to prevent corrosion and maintain accuracy.

Usage recommendations

For best results, use steady, controlled drilling speeds and support long overhangs or workpieces to reduce vibration. When drilling deep holes, periodically withdraw the bit to clear chips and reapply lubricant if needed. Verify chuck capacity and balance to avoid excessive runout that can affect hole quality.
