Product overview

The DSPIAE PT-HD is an entry-level hand drill for pilot holes and pinning work in plastic kits and resin parts. It uses the common 3.175 mm (1/8″) shank standard, so compatible bits from other makers fit, while the reversible cap changes the body length when you need additional reach.

ABS plastic body with a zinc alloy quick-exchange chuck and magnetic locking system
Includes five tungsten steel bits: 0.5, 0.8, 1.0, 1.5 and 2.0 mm
Polygonal cross-section helps stop the drill rolling across the workbench
Bearing connection supports smooth rotation during controlled manual drilling
Lightweight 52 g construction

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.
