Milwaukee vs Ryobi Reciprocating Saw

Milwaukee vs Ryobi: Which reciprocating saw is better for you?

Milwaukee and Ryobi are both owned by the same parent company (TTI), but they target very different users. Milwaukee's M18 Fuel line is built for tradespeople who need maximum power, durability, and runtime on a job site. Ryobi's One+ system is designed for homeowners and DIYers who want a versatile, affordable tool that works well for occasional use.

This comparison focuses on their flagship reciprocating saws: the Milwaukee M18 Fuel Sawzall (model 2626-20) and the Ryobi P518 One+ 18V Reciprocating Saw. We look at power, build quality, battery ecosystem, and value to help you decide.

Power and performance

The Milwaukee M18 Fuel Sawzall uses a brushless motor that delivers up to 3,000 strokes per minute (SPM) with a 1-1/8-inch stroke length. It also features a 4-position orbital action that lets you switch between straight cutting for metal and aggressive orbital cutting for wood. This gives it a clear advantage in speed and efficiency when cutting through thick lumber, nail-embedded wood, or metal pipe.

The Ryobi P518 has a brushed motor that also reaches 3,000 SPM but with a shorter 1-inch stroke. It lacks orbital action, meaning it cuts in a straight back-and-forth motion only. For cutting 2x4s, plywood, or thin metal, the Ryobi is perfectly capable. However, when tackling heavy demolition or thick materials, the Milwaukee will cut faster and with less effort.

Battery ecosystem and runtime

Milwaukee's M18 system is one of the most extensive in the pro market, with over 200 tools. The batteries are high-capacity (often 5.0Ah or 12.0Ah) and feature Redlink intelligence for optimized performance. The saw is compatible with all M18 batteries, including the compact CP2.0 and high-output HD12.0.

Ryobi's One+ system is the largest in the DIY space, with over 280 tools. The P518 works with any Ryobi 18V One+ battery. While the batteries are generally less expensive than Milwaukee's, they also have lower capacity and power output. For light use, a 4.0Ah Ryobi battery provides decent runtime, but heavy cutting will drain it faster than a Milwaukee equivalent.

Build quality and durability

The Milwaukee Sawzall is built to withstand job site abuse. It has a metal gear housing, rubber overmold for grip, and a sealed switch to keep out debris. The FIXTEC blade clamp is quick and secure, and the counterbalance mechanism reduces vibration significantly, reducing user fatigue.

The Ryobi P518 has a plastic housing and a more basic build. It is not designed for daily drops or harsh conditions. The blade clamp works well, but the vibration is more noticeable during prolonged cuts. For a homeowner who treats tools with care, the Ryobi will last for years. For a professional, the Milwaukee is the only choice.

What to check before buying a reciprocating saw

• Stroke length: Longer stroke (1-1/8") cuts faster and is better for demolition. Shorter stroke (1") offers more control for precision cuts.
• Orbital action: Allows the blade to move in an oval path for faster wood cutting. Essential for heavy demolition, less important for metal.
• Vibration control: Counterbalance mechanisms reduce fatigue. Important if you will be cutting for extended periods.
• Blade change system: Keyless clamps are standard. Look for a tool-free system that holds blades securely.
• Battery compatibility: Consider the entire tool ecosystem. A saw is just one part of a larger system.

Mistakes to avoid when choosing

• Buying too much saw for light use: If you only cut a few 2x4s a year, a pro-grade Milwaukee is overkill. A Ryobi will save you money.
• Buying too little saw for heavy work: For daily demolition, a brushed Ryobi will struggle and wear out quickly. Invest in the Milwaukee.
• Ignoring the battery system: If you already own Ryobi or Milwaukee tools, stick with that platform to avoid buying new batteries and chargers.
• Not checking blade compatibility: Both saws use standard 1/2-inch shank blades, but some specialty blades may not fit all models.
