Product overview

DSPIAE ZPB push broach bits are tungsten steel bits for scribing panel lines into ABS, PS, PE, resin and 3D printed parts. Most broach bits have a trapezoid cutting end, so the line widens each time you go over it. The ZPB is ground to a true 90° straight edge, so repeated passes keep the line the same width. Tolerance is under 0.003 mm; the bits are mirror polished and the edge treated against chipping. Each bit comes in a coloured storage case that doubles as a short handle; for longer work, fit it in a 3.175 mm holder, sold separately.

  • DSPIAE's guide for panel lines: 0.125–0.15 mm at 1/144, 0.15–0.2 mm at 1/100, 0.2–0.3 mm at 1/60
  • Shank diameter 3.175 mm
  • Holder not included

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.
