DSPIAE ZPB Straight Edge Broach and DSPIAE GS Step Scraper are precision tungsten-steel cutting bits designed for clean, controlled surface processing—ideal for panel line work, seam refinement, and mechanical detailing. The ZPB series focuses on straight-edge broaching/engraving with multiple blade widths, while the GS Step Scraper uses dual-size “step” blades to help turn plain seams into crisp, panel-like mechanical lines.

ZPB Straight Edge Broach – best for
- Refining panel lines and keeping groove width consistent
- Opening / widening existing lines with better control than freehand blade work
- Cutting clean straight micro-grooves for DIY surface detailing
GS Step Scraper – best for
- Step scraping to create crisp “mechanical seams” and layered panel separation
- Seam conversion: turning combined seams into panel-like lines with a stepped groove
- Fast size switching: each blade has two sizes on one bit

How to use (quick tips)
- Make light passes first, then deepen gradually—this keeps edges cleaner and reduces slipping.
- For step scraping, keep the tool flat and stable, and work slowly along the seam to maintain a consistent step.
- Clean dust from the groove frequently so the cutting edge stays crisp.
Notes
- These are precision cutting tools. Use care during installation and storage.
- For best results, practise on spare plastic first to match the bit size to your preferred panel line style.
