Product overview

Tamiya Modeling Drill Chuck 74086 is a hand-operated alternative for 1.5–6.5 mm drill bits, covering sizes beyond the smaller pin vises without using a powered drill. A keyless three-jaw chuck centres and secures the bit, while the large blue ergonomic handle provides the grip for manual drilling. The tool suits scale-model, R/C-model and Mini 4WD assembly.

The chuck accepts drill bits from 1.5 mm to 6.5 mm.
Its keyless mechanism uses three jaws to hold the bit.
A large blue ergonomic handle is fitted.
Intended applications include scale models, R/C models and Mini 4WD kits.

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.
