UPX Series 0.2-2.95mm Carbide Micro Drill Bits with 3mm Shank ±0.005mm Tolerance for PCB Jewelry

The UPX Series 3.0mm Shank High Precision Carbide Micro Drills are specifically engineered for ultra-precise micro hole drilling where stability, accuracy, and tool life are critical. Featuring a fixed 3.0mm shank diameter larger than the cutting diameter, this design dramatically improves clamping rigidity and eliminates runout, vibration, and premature tool breakage commonly encountered in micro drilling operations.

With cutting diameters ranging from 0.2mm to 2.95mm in precise 0.05mm increments and a diameter tolerance of ±0.005mm, these drills deliver exceptional hole consistency and surface finish even in the most demanding applications.
