Special Features

  • Precise Shank & Cutting Diameter Options: Shank diameter is approx. 3.175mm, a standard size for many CNC collets and chucks. Overall mini drill bit set length is 38.1mm (1.5 inches). Cutting edges diameters are available in multiple options, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.7mm, 1.2mm, 1.3mm, or 1.4mm per set. This range allows you to select the exact hole size needed for PCB vias, SMT pads, or model engineering
  • Sharp Flute & Large Chip Discharge Space: Each bit features a sharp twisted flute design. The flute creates a large scraps discharge space, allowing chips to escape smoothly. This low‑resistance discharge micro drill set prevents clogging inside the hole, which is common when drilling small diameter holes in PCB or plastic. The clean chip flow improves the quality of the hole wall
  • Tungsten Steel + White Steel Material: These pcb drill bits are made from tungsten steel and white steel. The mini drill bits provide a sharp cutting edges through a fine grinding process. Tungsten steel offers hardness for drilling hard materials like stainless steel and copper. White steel tiny drill bits add edges retention for repeated use on PCB boards. The micro drill bits reduce cutting force during operation, which helps prevent broken drills
  • Storage Box & Easy Bit Exchange: The 10 tungsten drill bits come in a compact plastic storage case measuring 8.7 x 5.3 cm (3.42 x 2.08 inches). Jewelry drill bits have its own holder slot inside the box, keeping them organized by size and preventing damage to cutting edges. Hand drill bits set is portable for field repairs or lab use. Changing bits is straightforward, simply lift the bit from its slot and insert into your CNC spindle or hand drill
  • Wide Use: These drill bits work on printed circuit boards for creating solder holes and component leads. Precision drill bit set is also suitable for SMT (surface mount technology) board modifications, CNC machining, mold work, sculpture, and jewelry repairs. The micro drill bits for carburetor jets can drill through hard materials including plastic, copper, and stainless steel. For craft work, they provide fine hole placement without cracking brittle substrates
