Micro Drill Bits for Circuit Boards

Available24 products
These micro drill bits are small-diameter drill bits used for making precise, tiny holes with close tolerances. The geometry and material of the bits provides optimal chip clearance when drilling into epoxy resin and phenolic resin circuit boards. The drill bits are used in handheld drills and machine setups such as drill presses.

Wire-Size Bright Finish Spiral-Flute Solid Carbide Micro Drill Bits for Circuit Boards

Wire-Size Bright Finish Spiral-Flute Solid Carbide Micro Drill Bits for Circuit Boards
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.

Fractional-Inch Bright Finish Spiral-Flute Solid Carbide Micro Drill Bits for Circuit Boards

Fractional-Inch Bright Finish Spiral-Flute Solid Carbide Micro Drill Bits for Circuit Boards
These drill bits come in standard sizes expressed in fractional inches. 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.
