Frequently Asked Questions

How do I choose between L-series?

The L-series number corresponds to flute length. Thicker substrates need longer flutes (higher L-number) for the drill point to fully penetrate before the threads engage. L1-L2 for thin material, L3-L4 for medium, L5-L6 for heavy structural steel.

When should I use tungsten carbide vs HSS?

Tungsten carbide is recommended for high-volume production (100,000+ pieces) and for all stainless steel screw production due to its superior wear resistance. HSS is a cost-effective option for lower volumes or where die cost is a primary concern.

Is PVD coating necessary?

For carbon steel screw production, PVD coating is optional but extends die life. For stainless steel production, CrN coating is strongly recommended to prevent galling (adhesive wear) which is the primary cause of die failure in stainless steel applications.
