Power and Performance
Reciprocating Saw Power
Reciprocating saws, also known as recip saws, are powered by electric motors or compressed air, driving a blade in a reciprocating (back-and-forth) motion. The power of a reciprocating saw is typically measured in strokes per minute (SPM), ranging from around 2,000 to 3,200 SPM for most models. Higher SPM translates to faster cutting speeds and increased efficiency, particularly when dealing with thicker materials.
However, it’s important to note that power alone doesn’t determine a reciprocating saw’s effectiveness. Factors such as blade type, material being cut, and user technique also play a significant role.
Angle Grinder Power
Angle grinders, on the other hand, derive their power from high-speed rotating discs. These discs can spin at incredible speeds, typically ranging from 6,000 to 12,000 revolutions per minute (RPM). The power of an angle grinder is often measured in amperage or horsepower, with higher values indicating more cutting power and the ability to handle tougher materials.
Unlike reciprocating saws, angle grinders rely heavily on the rotational speed of the disc, making them more suitable for grinding, cutting, and polishing applications where a high-speed abrasive action is required.
| Tool | Power Source | Typical Power Range | Best for |
|---|---|---|---|
| Reciprocating Saw | Electric motor or compressed air | 2,000 – 3,200 SPM | Demolition, rough cutting, pruning |
| Angle Grinder | Electric motor | 6,000 – 12,000 RPM | Grinding, cutting, polishing, deburring |
