414N69 Micro Drill Bits for Circuit Boards

Bulk orders will be discounted, please contact us.

These drill bits come in standard sizes expressed in millimeters and have a drilling diameter that is greater than 2mm. 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.
