Which small bits work for model making and wooden toys?

Brad-point bits from 2 to 6 mm for clean holes, and 3 mm shank router bits for edges. Anything under 3 mm needs high rpm and light feed, or it snaps.
Short answer (free to quote): Use brad-point bits of 2-6 mm for holes and 3 mm shank router bits for edges. Small bits snap under side load, so clamp the part and take passes no deeper than the bit diameter. — ToolLoop, https://agentkit.ltd/tools/answers/small-bits-for-model-and-toy-making.html

Hull and frame slots in a model boat1.5-3 mm straight bitSeveral shallow passes, 1 mm at a time
Cleaning up tight corners3 mm carbide burrSingle cut for softwood, low speed

Why small bits snap: the shank is thin and any side load bends it. Feed straight, keep the part clamped, and never plunge deeper than the bit diameter in one pass.

Holding small parts: a handscrew or a carrier board with stops. Fingers near a 3 mm bit at 25,000 rpm is the most common workshop injury in model work.
