Internal Water Router Bits (Iw Bits)

Internal water (IW) router bits feature built-in water channels that deliver coolant directly to the cutting surface. This internal water feed keeps the diamond segments cool, extends tool life, and produces cleaner cuts on granite, marble, quartz, and quartzite. IW bits are preferred for high-production shops where consistent cooling is critical for edge quality.

• Built-in water channels for direct coolant delivery
• Extended diamond life and cleaner edge finishes
• Preferred for high-production stone fabrication
