DSPIAE: Integral Stepless Circular Cutter

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.

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. Allow approximately 0.1 mm tolerance when setting the radius by hand.
