Description

Solid PCD micro drills are designed for small-diameter precision holes in abrasive, composite, and hard-brittle materials. They are a practical choice when ordinary micro carbide drills wear too quickly, lose edge stability, or create unstable hole quality in materials such as CVD SiC, ceramics, graphite, aluminum/fiberglass composites, CFRP/GFRP, and other non-ferrous or advanced materials.

Where this tool fits

This tool is especially relevant for applications where the hole is small but the material is demanding. In aluminum/fiberglass composite parts, the aluminum side may form burrs while the fiberglass layer can chip or fray. In CVD SiC and similar hard-brittle materials, the priority is controlled edge behavior rather than heavy material removal.

Key features

• Small-diameter drilling for D0.5, D1.0, and customized micro-hole sizes
• Solid PCD cutting edge for abrasive and hard-brittle materials
• Suitable for CVD SiC, ceramics, graphite, fiberglass composites, CFRP/GFRP, aluminum composites, and non-ferrous materials
• Supports cleaner hole edges, reduced chipping, and more stable hole quality under suitable machine conditions
• Custom point geometry, flute length, neck relief, and shank size available according to the workpiece and machine spindle

Typical applications

• Micro-hole drilling in CVD SiC, ceramics, sapphire, graphite, and precision electronic materials
• Fine-hole machining in aluminum/fiberglass and other composite parts
• Small holes where burrs, chipping, breakout, or tool wear are the main process problems
• Custom PCD drilling tools for high-value precision components

RFQ information to send

Common buyer questions

Can this solid PCD micro drill machine CVD SiC and other hard-brittle materials?

Yes, it can be considered for CVD SiC, ceramics, graphite, sapphire, and similar hard-brittle or abrasive materials. The final drill geometry and cutting parameters should be selected based on material thickness, hole size, edge chipping limits, spindle runout, and coolant or air-blast conditions.

Is it suitable for aluminum/fiberglass composite parts?

Yes. It is suitable for small holes where aluminum burrs and fiberglass chipping or fraying need to be controlled under stable machine conditions.

What should buyers send for a recommendation?

Send the workpiece material, hole diameter, hole depth, tolerance, machine spindle condition, coolant or air-blast method, current tool information, and photos of burrs, chipping, breakout, or tool wear.
