The Ryobi Speed Saw is a rotary cutter that quickly and easily performs tasks previously performed by several other tools. Based on the Ryobi One+ charge system, the Speed Saw assumes that you have other One+ tools and doesn't include a battery or charger. They Speed Saw can use a number of different bits and attachments to perform a number of different cutting tasks.
The Ryobi Speed Saw includes an attachment to cut circles ranging from 3½ inches in diameter to 12 inches in diameter. This jig attaches to the Speed Saw and provides a pivot point on which the cutter can rotate in a perfect circle. You may be able to cut larger circles by attaching a string to a center pivot point and tying the other to a screw, nail or other center pivot point. When using a string, be sure not to allow the string to become caught in the rotary cutter.
The Ryobi Speed Saw is especially useful for cutting odd or unusual shapes. Because its blade operates at such high speed and is so thin, it allows detailed scroll cuts in a wide range of materials. When cutting intricate patterns, mark the pattern clearly on the material and work slowly to avoid slipping outside the pattern.
The Ryobi Speed Saw is especially well-suited for cutting openings for new electrical outlets and light switches. It can easily cut square openings for various electrical junction boxes, especially those that later will be covered with face plates.
The Ryobi Speed Saw includes bits for cutting both drywall and plywood. The saw excels at cutting drywall. It is also good for cutting plywood up to ?-inch thick. It can also, however, cut plywood ½-inch thick, but with some difficulty. It may be able to cut some plastics, but its 26,000 Revolutions Per Minute (RPM) cutting speed may generate enough heat to melt some plastics.
