Kyocera Series 430 Carbide Drill - PCB Type

The Kyocera Series 430 is a high-performance Hybrid Flute Undercut Drill engineered for the demanding requirements of modern PCB manufacturing. Featuring a unique 2-into-1 hybrid flute design, this tool is built to deliver elevated overall performance, ultra-precise hole location, and superior hole wall quality. Whether you are working with standard or advanced PCB materials, the 430 series ensures reliable, repeatable results with maximum tool strength and long endurance.

• Hybrid Flute Geometry: Patented 2-into-1 flute undercut flute design combines the strength of a standard drill with the enhanced debris-evacuation efficiency.
• Superior Hole Quality:  Minimizes resin smear and burr formation for cleaner, more consistent plating.
• High Precision:  The 130° four-facet point geometry ensures minimal drill deflection, providing ultra-precise hole positioning, even in high-stack applications. 
• Broad Material Compatibility:  Ideal for high Tg FR-4, polyimide, and other advanced composite substrates.
• Maximum Tool Life:  Manufactured from premium micrograin carbide, to provide exceptional wear resistance and long-lasting endurance in high-volume production environments.
