Questions about this product

Will these micro drill bits fit my standard rotary tool or CNC machine?: Yes, they feature a standard 1/8-inch shank. They work perfectly with standard CNC spindles, rotary tools, and drill presses that accept 1/8-inch collets.
What materials can I safely drill with this tungsten steel set?: These bits are designed specifically for printed circuit board drilling. They easily cut through tough laminate materials like FR-4, CEM-1, and CEM-3.
How fast should I run these bits, and do I need coolant?: Run these bits at high speeds, typically between 15,000 and 80,000 RPM. You do not need liquid coolant; dry drilling or a minimal air blast works best. Because they are extremely thin, use a steady machine setup to prevent snapping.
