DSPIAE GS gap scrapers are tungsten steel bits that cut a step along the edge of a plastic part, adding the layered, mechanical look that panel lines alone cannot give. Every bit has two widths in one: a narrow tip at the very end and the full width of the blade behind it, so one scraper cuts two sizes of step. The corners are rounded so the bit does not damage the detail next to the edge you are working on. The shank is 3.175 mm and the bit needs a holder of that size, sold separately.
Five sizes: 0.2/1.5, 0.3/0.6, 0.4/0.8, 0.5/1.0 and 0.7/1.4 mm
Two widths on every bit, both engraved on the shank

Notes · Q & A
What is a 3.175 mm shank and why does it matter?+
3.175 mm is 1/8 inch, a common shank size for push broaches, scrapers and engraving bits. A holder grips one shank size only: a thinner shank sits off-centre and wobbles, a thicker one will not go in. Check the shank before buying bits for a holder.
Push broach or scriber — which do I need for panel lines?+
A scriber drags a point through the plastic, which suits fine lines and curves. A push broach has a flat edge of a set width, so it cuts a groove of exactly that width and cleans out existing panel lines evenly. Many modellers use both.
How do I keep a scribed line straight?+
Run the tool against a guide such as a flexible template or a strip of tape, and make several light passes rather than one deep one. Pressing hard makes the tip jump the guide and skate across the panel.
How do I look after broach and scraper tips?+
Cap them when not in use, use them on plastic and resin only, and never drop them. Very hard tips are also brittle, so a sideways twist or a fall can chip the edge. Brush out plastic swarf after each session.
