414H85 Micro Drill Bits for Circuit Boards

Bulk orders will be discounted, please contact us.

Wire-size drill bits come in standard sizes that correspond to American Wire Gauge (AWG) sizes. The larger the wire size, the smaller the bit. Carbide micro drill bits provide excellent hardness, wear resistance, and heat resistance. They create precise holes with a smooth finish and often eliminate the need for reaming the hole after drilling. Carbide bits require a rigid setup such as a fixed-spindle machine. The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
