DSPIAE Electric Grinding Pen
The DSPIAE ES-P is a cordless electric grinding pen designed for scale modelers who need precise material removal in tight spaces — seam lines on Gunpla, mold marks on resin parts, surface prep on plastic kits, or fine engraving work on any hobby material.
At 58g it handles like a pen rather than a power tool, which means you get direct tactile feedback and control over every pass. Three speed settings let you match the RPM to the task: slow for delicate engraving, medium for seam removal, full speed for aggressive grinding or sanding with the disc attachments.
Speeds and power
- Speed 1: 5,000 rpm — fine engraving, light surface work
- Speed 2: 10,000 rpm — seam removal, panel line cleanup
- Speed 3: 18,000 rpm — aggressive grinding, sanding with discs
Battery and charging
- Approximately 1 hour of runtime per charge
- USB charging — no proprietary cable needed
- Digital display shows battery level and selected speed
What you can do with it
- Remove mold lines and sprue attachment marks from plastic and resin
- Engrave panel lines, rivets, and surface detail
- Open and shape cockpit interiors, hatches, and vents
- Prepare resin prints for painting by removing support scarring
- Sand curved or concave surfaces using the disc attachments
- Detail work on diorama elements and scratch-built parts
