Description

These micro-diameter PCD drills are intended for precision micro-hole machining where conventional tools struggle with brittle material behavior, edge wear, or inconsistent hole quality. They are a practical starting point for RFQs involving very small diameters, hard brittle workpieces, and process stability requirements.

Where this tool fits

• Micro-hole drilling from D0.3-D3
• Precision drilling where edge sharpness and consistent hole quality matter
• Applications where the buyer needs a PCD tool recommendation based on material and hole data

Typical materials

• Monocrystalline silicon
• Technical ceramics
• Sapphire and other hard brittle materials
• Other advanced materials where carbide or coated tools are not stable enough

Application scenarios

• Semiconductor-related components
• Precision electronics and optical material processing
• Small-hole machining where burr, chipping, or dimensional variation must be controlled

Send RFQ with drawing, material, and hole size

For a useful recommendation, send the workpiece material, target hole diameter, hole depth, tolerance target, machine type, and current drilling problem. Use Full RFQ when drawings or process data are available, or start with Contact Us for a quick first review.
