HSS Remains the Most Popular Choice

For traditional Wenxing key machines, High-Speed Steel (HSS) cutters continue to be the preferred option.

Advantages of HSS cutters include:

• Lower initial cost

• Easy re-sharpening
• Stable cutting performance
• Suitable for older machines with spindle wear

Typical materials include:

• M2 HSS
• M35 Cobalt HSS

For most locksmith shops, M2 HSS provides an excellent balance between cost and performance.

Can Carbide Cutters Be Used?

Yes.

For locksmith shops with high daily production volumes, carbide cutters can provide:

• Longer service life
• Higher wear resistance
• Improved dimensional stability
• Reduced downtime for cutter replacement

However, for traditional Wenxing machines primarily used for residential key duplication, HSS cutters usually remain the most economical solution.

Re-Sharpening and Maintenance

One reason for the long popularity of Wenxing cutters is their excellent re-sharpening capability.

To maximize cutter life:

• Avoid excessive cutting pressure.
• Keep the spindle and arbor clean.
• Check machine runout regularly.
• Re-sharpen the cutter before severe wear occurs.

Proper maintenance can significantly extend service life and maintain cutting accuracy.
