Tamiya 74049 is a five-bit twist-drill set covering common diameters for opening mounting holes, enlarging locating points and adding detail to plastic models. It provides 1, 1.5, 2, 2.5 and 3 mm cutters rather than one specialised size. Each bit has a straight shank matching its cutting diameter and can be used with a compatible pin vise or Tamiya Electric Handy Drill. A clear hinged case keeps the five sizes together between jobs.
Five drill bits are included: 1, 1.5, 2, 2.5 and 3 mm.
Compatible with the Fine Pin Vise D 74050 and Electric Handy Drill 74041.
Each bit's shank diameter matches its cutting diameter.
Supplied in a clear hinged plastic storage case.

Notes · Q & A
What size drill bit do I need for pinning miniatures?+
For most metal and resin minis, 0.8mm to 1.0mm suits brass rod pinning. Drop to 0.3–0.5mm for magnets and small barrel-drilling. Match the bit to your rod or magnet diameter rather than guessing, and check the product description for sizes stocked.
Why do my micro drill bits keep snapping?+
Nearly always side load — the bit flexing because the pin vice isn't held straight, or forcing it through resin. Let the bit cut at its own pace, keep the vice vertical, and clear swarf often. Sub-0.5mm bits are glass-brittle.
Do I need a pin vice or can I use a powered rotary tool?+
A hand-held pin vice gives the control you want for fine work and rarely melts plastic. Powered tools spin fast enough to friction-melt resin and plastic and snap small bits, so keep them for larger holes only.
How do I start a hole without the bit wandering?+
Mark the centre first with a sharp blade tip or a scriber to make a small divot. That gives the bit a seat to bite into, so it starts on the mark instead of skating across a curved or glossy surface.
