PCB Drill Bit Set 0.8/1.0/1.5/2.0/3.0/4.0mm

These PCB Drill Bits are precision-ground micro drill bits designed specifically for drilling clean, accurate holes in printed circuit boards, fibreglass (FR4), copper-clad laminates, thin plastics, acrylic, and soft materials. Available in six sizes — 0.8mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm, and 4.0mm — covering the most commonly needed hole diameters for through-hole component leads, via holes, mounting holes, and header pin clearances encountered in electronics prototyping and PCB fabrication.

Manufactured from steel with a black oxide nitride surface finish for improved hardness, heat resistance, and corrosion protection, these bits maintain a sharp cutting edge under the high RPM conditions of PCB drilling. The straight shank and precision-ground twist geometry ensure concentricity and accurate hole sizing on entry, minimising burr formation and breakout on the underside of the board — critical for clean, professional PCB work.

Compatible with all standard PCB drill presses, mini hand drills, rotary tools (Dremel, Proxxon), and electric pin vise drills. The 0.8mm and 1.0mm bits are ideal for standard via holes and 1mm component lead holes; the 1.5mm and 2.0mm bits suit transistor and connector leads; the 3.0mm and 4.0mm bits handle mounting holes and large connector clearances. An essential consumable for every electronics workbench, repair station, and PCB prototyping setup.
