Product overview

The DSPIAE XDB-S03 handles the large end of the range: pinning heavier parts, forming magnet recesses and drilling through thicker model materials. Its six tungsten bits are arranged as three close pairs separated by larger gaps, rather than continuous 0.1 mm increments. This layout gives you paired choices around three larger diameters without implying that the sizes between them are included.

Individual diameters are 2.0, 2.1, 2.5, 2.6, 3.0 and 3.1 mm.
The set omits 2.2–2.4 mm and 2.7–2.9 mm sizes.
All six share the Ø3.175 mm shank that the Mobius (AT-MHD) is built to take.
Only the Mobius collet engages the flat spin-lock feature that keeps the bit from slipping.
We stock the PT-HD, whose 3.175 mm chuck accepts these bits without that engagement.

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.
