Handheld Drilling Equipment
Pneumatic handheld rock drills, sinker drills, breakers, integral drill steels, chisels and hose sets for secondary breaking and small-diameter drilling.
Features
- Handheld drills are specified by air consumption and weight, because both decide whether one operator can work a full shift with them.
- Integral drill steels combine rod and bit in one piece and suit shallow holes where changing bits costs more time than replacing the steel.
- Hex shank size on drill and steel must match, and worn shanks damage the drill's chuck.
- Air line diameter and length change the pressure actually reaching the tool, so hose specification is part of tool selection.
- Line lubricators are needed on percussive tools; running dry is the most common cause of early failure.
