What it does

See your work clearly through the center hole so you stay on target while dust gets pulled away into your shop vac.
Fits Karcher WD 3 and other 35mm hose connections, so your existing vacuum system works without adapters.
Creates suction against the wall, holding itself in place so you can drill with both hands free.
Pulls dust at the source before it spreads, keeping your workshop cleaner and your tools lasting longer.

Drill without the mess. This 3D-printed vacuum sucker attaches to your Karcher shop vac and pulls dust right from the hole as you work. You keep full sight of what you are drilling while air moves through the center opening, picks up debris, and sends it straight into your vacuum. The suction holds the adapter against the wall on its own, so both your hands stay free for the drill.

Sized for 35mm outer diameter hose connections, this tool fits Karcher WD 3 models and compatible shop vacuums. The open design beats cup-style adapters because you never lose visibility. Air flows in, dust flows out, and your workspace stays clear.
