PACKAGE ROLEManual tool
SUPPLIED / PACKAGE DETAILPunch tool and one 2 mm plus one 3 mm bit
The 74122 makes the small circular pieces themselves. Its 2 mm and 3 mm punch bits are useful for model details or circular masking pieces, with plastic plate explicitly limited to 0.5 mm thickness. That is a more specific operation than enlarging a hole with a drill or tracing a circle with a stencil.
The wide rotating grip supports the turning action, and the bits exchange with a single-touch mechanism. The seller names chrome-molybdenum punch bits and explains that the punched plastic pieces can be removed from the tool. The 2 mm and 3 mm figures are disc diameters; 0.5 mm describes the permitted plastic plate thickness.
Choose the DSPIAE MT-C when an adjustable paper-circle diameter is the priority instead of these two fixed sizes. If you want to engrave or mark an outline on a model surface without cutting a disc free, the 74150 circle stencil is the more relevant comparison. Do not transfer the punch’s plastic-sheet limit to those other tools.

Check the selected size, working profile and supplied parts on Amazon before ordering.
Where this model is useful
A fixed-size disc-cutting operation distinct from drilling.
Rotating grip and quick exchange are useful handling details.
Trade-offs to check
The 0.5 mm limit is for plastic plate, not a universal sheet-material thickness.
What to check before choosing
Diameter versus thickness
Match both the desired disc diameter and the plastic-sheet thickness; they are separate measurements.
Your questions about this product
Should I drill the hole instead of using this punch?
Choose the punch when you want the circular piece it cuts out, for a detail or masking disc. A drill makes a hole and removes material differently.
When would the MT-C circle cutter be preferable?
It offers adjustable 1–50 mm paper-circle diameters. This punch focuses on 2 mm and 3 mm pieces with its own explicit plastic-sheet limit.
What is the role of the rotating grip?
It supports the hand-turning action while using the punch. The bits exchange with a single-touch mechanism.
A continuously adjustable 1–50 mm diameter setting cuts circular pieces rather than only tracing their outlines.
