The RYOBI® 18V ONE+™ Speed Saw™ Rotary Cutter is an excellent choice for a variety of cutting applications. The saw accepts 1/4 in. and 1/8 in. bits and features an adjustable depth setting that makes cutting in different types of materials easy. The spindle lock helps make 1-wrench bit changes simple, and the ergonomic design helps you finish your project comfortably. The 18V ONE+™ Speed Saw is sold as a bare tool, allowing you to build on your ONE+™ collection without spending additional money on batteries and chargers with each tool purchase. Best of all, like every RYOBI® 18V ONE+™ blue or green tool, this Speed Saw works with any 18V ONE+™ battery. Upgrade to lithium-ion or LITHIUM+™ batteries for lighter weight and better performance.
