The 20V cordless platform
One battery runs both the pump that holds the tool and the hammer that does the work.
Two loads, one pack
The VACDRILL is unusual in that its battery does two jobs. It drives the rotary hammer, which is a high, intermittent load, and it drives the vacuum pump, which is a lower but continuous load that must never be interrupted while the tool is attached to a wall.
Published configurations are 20 V 6 Ah lithium-ion and 20 V 5.0 Ah lithium-ion.
Why cordless matters here specifically
The whole proposition is a tool that goes where a person cannot comfortably brace themselves — up a ladder, on a soffit, on a facade. Trailing a mains lead to that position reintroduces exactly the hazard the tool removes.
It also means the machine can be placed and left anchored while the operator repositions.
Managing runtime
- Carry a second pack. The pump draws whenever the tool is attached, so idle attached time costs charge.
- Detach when you are not drilling rather than leaving the tool anchored across a break.
- Cold packs deliver less current; in winter keep spares out of the cold.
Questions about this
How long does a battery last on a shift?
It depends heavily on attached time, not just drilling time, because the pump draws whenever the tool is anchored. Detach between holes and carry a spare pack for a full day of anchor work.
What happens if the battery dies while the tool is attached?
Treat this as the situation to design out. Detach during breaks, monitor charge, and never leave the tool anchored — especially overhead — with a pack you have not checked.
