PT-C Integral Circular Cutter

DSPIAE PT-C Integral Stepless Circular Cutter is a precision tool for cutting clean, accurate circles for modelling work—ideal for making round masks, decals, and circular parts from thin sheet materials. Its stepless radius adjustment and clear scale panel help you set sizes quickly and keep your cut aligned with the work surface.

Key features

• Integral, all-in-one design for stable circular cutting.
• Clear 3D scale panel with concentric circles so you can keep visual contact with your work for faster positioning.
• Adjustable cutting pressure: the pressurised coil mount can be tuned for smoother cutting while helping protect the cutting bit for longer service life.
• Magnetic storage compartment to secure cutting bits and reduce the chance of losing them.

Diameter range

• Radius scale: 1mm to 50mm
• Manual adjustment tolerance: approx. ±0.1mm (typical for hand adjustment)

Best uses

• Cutting masking tape/film circles for airbrushing and colour separation
• Making round decals or templates
• Cutting circles from paper and thin plastic sheet for scratch-building details

How to use

• Place the anti-slip pad under the tool (recommended) and set your material flat.
• Adjust the radius to your target size using the scale panel for reference.
• Start with light pressure, then make multiple passes to deepen the cut for the cleanest edge.
• For thin materials, avoid forcing through in one go—let the cutter do the work.

Notes

• The cutting bit is sharp—take care during installation and handling.
