The Bosch KEO is a compact and lightweight reciprocating garden saw powered by an integral 10. 8 volt lithium, ion battery. It has been designed to fill the gap between secateurs and chainsaws, where the usual alternative for cutting back medium, sized branches would be a handheld pruning saw. It is lightweight and features a detachable A, grip hook for improved performance even on unsupported branches. The unique A, hook removes the need for a second hand to support the branch while cutting. The KEO?s Swiss precision blades provide a clean cut, and the Bosch SDS system makes blade changing easy and tool, free. The cutting diameter achieved can be up to 60 mm with the A, grip hook attached, and 80 mm without. It is designed to suit a wealth of different cutting applications around the house and garden, using any of the blades from the Bosch ?All, Purpose? saw range.
