Product overview

The DSPIAE PT-C is a compass-style tool for scribing and cutting repeatable circles in plasticard, masking tape, film, decal sheet and thin styrene. Its stepless adjustment lets you set any position on the scale rather than choosing fixed increments, making it useful for canopy and wheel-hub masks, portholes, hatches and detailing discs.

Allow approximately 0.1 mm tolerance when setting the radius by hand
Transparent scale panel with concentric guides keeps the work visible during positioning
Spring-loaded bit mount provides adjustable pressure for lighter films or firmer sheet material
One 45° cutting bit is supplied; the magnetic compartment has space for three
Replacement bits are the DSPIAE MT-CB set, sold separately

Notes · Q & A

What is single-edge (flush) vs double-edge cutting on sprue nippers?

Single-edge, or flush, cutters have one flat face and one bevelled blade, leaving a near-clean cut on the part side. Double-edge cutters bevel both sides and pinch, leaving a small nub you then trim. For plastic kits, flush is worth it.

Can I use hobby sprue cutters on metal miniatures or wire?

No. Fine flush cutters are ground for soft plastic and resin; metal minis, brass rod and staples will chip or roll the edge. Keep a separate, more robust pair for metal and save your good cutters for plastic.

How do I cut parts off the sprue without stress marks?

Cut twice. Leave a little sprue on the first pass, then trim flush away from the part, blade flat to the surface. Cutting hard against the part whitens and dents the plastic as the blades pinch it.

Why has my cutter stopped cutting cleanly?

Usually a nicked or misaligned edge from cutting something too hard, or dried glue in the joint. Wipe the blades, add a drop of oil to the pivot, and only cut material the tool is rated for. A chipped flush edge cannot be honed back.
