Abstract
A hand-power tool includes at least one tool spindle and a drive unit configured to drive the at least one tool spindle at a rotational speed greater than 10,000 min−1. The hand-power tool further includes at least one charging energy input and a tool chuck. The at least one charging energy input is arranged on a hand-power tool housing face that faces the tool chuck.
Claims16
A hand-held power tool, comprising:
- a hand-held power tool housing;
- at least one tool spindle;
- a drive unit configured to drive the at least one tool spindle at a rotational speed higher than 10 000 min−1;
- at least one charging energy input;
- a tool clamping chuck;
- and
- a hose coupling that connects the drive unit to the at least one tool spindle via a friction connection that is configured to slip in response to a block in the driven rotation of the at least one tool spindle,
- wherein the at least one charging energy input is arranged on a side of the hand-held power tool housing facing the tool clamping chuck such that, when the at least one charging energy input is engaged with a charger for the hand-held power tool, at least the tool clamping chuck of the hand-held power tool is surrounded by the charger by at least 90 degrees on at least one plane.
