Frequently Asked Questions (FAQ)

• Can this drill through metal?
  No, this manual hand drill is designed for softer materials like PCBs (FR4), plastic, resin, wood, and polymer clay. It will not drill through aluminum, steel, or thick metal plates.
• Are the drill bits included?
  Yes, the set comes with 25 High-Speed Steel (HSS) micro drill bits ranging from 0.5mm to 3.0mm.
• Will the 0.5mm bits break easily?
  Micro bits (0.5mm - 1.0mm) are inherently fragile. You must apply strictly downward pressure and avoid any side-to-side bending to prevent snapping.
• Does it need batteries or power?
  No, this is a 100% manual hand tool. You operate it by twisting the textured grip with your fingers.
• How do I change the drill bits?
  Hold the body of the pin vise and unscrew the textured top chuck counter-clockwise. Insert your new bit, and tighten the chuck clockwise until it grips the bit firmly.
• Can it hold bits smaller than 0.5mm?
  The chuck is optimized for 0.5mm to 3.0mm. Bits smaller than 0.5mm may not be gripped securely by the 3-jaw mechanism.
• Can I use these bits in a motorized Dremel or rotary tool?
  Yes, the HSS bits can be used in a motorized rotary tool, provided your tool has a collet small enough to grip the micro shanks.
• Is this suitable for drilling holes in sea shells or sea glass?
  No, shells and glass require specialized diamond-coated bits. These HSS bits will dull quickly and likely crack the glass.
• What is the best bit size for standard PCB component holes (like resistors or ICs)?
  For standard through-hole components (resistors, capacitors, DIP ICs), a 0.8mm or 1.0mm drill bit is typically the perfect size.
