Milwaukee 2834-20 M18 FUEL 7-1/4" Rear-Handle Circular Saw
Best Overall / FramingPros
- Exceptional torque rivals corded worm drives
- RapidStop brake stops blade in under 1 second
- Excellent dust collection port
Cons
- Heavy for prolonged overhead use
- Requires a high-capacity M18 battery for best performance
The 2834-20 is the flagship Milwaukee cordless circular saw. It uses the M18 FUEL brushless motor to deliver 5,800 RPM and enough torque to rip through pressure-treated lumber and stacked LVLs. Owner reviews consistently praise its power output, noting it cuts like a corded worm-drive saw without the cord.
The rear-handle design improves balance and line-of-sight for straight cuts, and the integrated RapidStop brake is a safety standout. The main drawback is weight: at over 10 pounds with a High Output battery, it is tiring for overhead work. It is built for professional framers who demand maximum performance.
Milwaukee 2833-20 M18 FUEL 7-1/4" Sidewinder Circular Saw
Best Value CordlessPros
- Lighter and more balanced than the rear-handle model
- Excellent value for the performance level
- Integrated rafter hook and LED light
Cons
- Less torque for stacked lumber than the 2834
- Dust port could be better positioned
The 2833-20 is the sidewinder (blade-left) version of Milwaukee's M18 FUEL line. It offers a great balance of power and weight, making it suitable for both framing and general construction. Owner reviews highlight its smooth cut and reliable brake system.
While it does not have the raw torque of the rear-handle 2834, it is significantly lighter and easier to handle for all-day use. It is the best choice for professionals who want a cordless saw that is powerful enough for most tasks without the extra weight.
Milwaukee 2732-20 M18 FUEL 6-1/2" Circular Saw
Best for DIY / TrimPros
- Very lightweight and compact
- Great for sheet goods and plywood
- Accepts M18 batteries for long runtime
Cons
- Cannot cut 2x material at 45 degrees
- Not suitable for heavy framing
The 2732-20 is a compact 6-1/2" saw designed for trim carpenters and DIY users. It is much lighter than the 7-1/4" models, making it easy to maneuver for cutting plywood, shelving, and trim. Owner reviews appreciate its precision and low vibration.
The smaller blade limits its depth of cut, so it cannot bevel-cut through a 2x4. It is ideal for workshop use and light construction where portability and ease of use are priorities. It is a solid choice for homeowners who already own M18 batteries.
Milwaukee 2626-20 M12 FUEL 5-3/8" Circular Saw
Best Compact / Light DutyPros
- Extremely lightweight and compact
- Perfect for one-handed use in tight spaces
- Uses the M12 battery system
Cons
- Limited cutting depth restricts use to thin materials
- Not for framing or pressure-treated lumber
The 2626-20 is part of Milwaukee's M12 line, offering a very compact and lightweight saw. It is designed for cutting drywall, plywood, and thin stock. Owner reviews praise its portability and ease of use for overhead cutting and tight spaces.
It is not a replacement for a full-size saw. The 1-9/16" depth of cut means it cannot cut through a 2x4. It is a specialized tool for electricians, plumbers, and DIYers who need a quick, small saw for light materials.
Milwaukee 6390-21 15-Amp 7-1/4" Worm Drive Circular Saw
Best CordedPros
- Unlimited runtime and consistent power
- Classic worm-drive gearing for high torque
- Excellent for long, straight rips
Cons
- Heavy and less portable than cordless
- Cord management can be a hassle
The 6390-21 is the corded workhorse of the Milwaukee lineup. It features a 15-amp motor and worm-drive gearing that delivers massive torque for the toughest cuts. Owner reviews note its reliability and power for ripping thick lumber and engineered beams.
It is heavier than any cordless model and requires a power source, but it never runs out of battery. It is the best choice for stationary jobsite work or for users who prefer the feel of a traditional worm-drive saw. The magnesium construction keeps the weight manageable for its class.
What to check before buying a Milwaukee circular saw
Blade size: 7-1/4" is standard for framing and can cut 2x lumber at 45 degrees. 6-1/2" and 5-3/8" saws are lighter but have limited depth. Choose based on your typical material thickness.
Battery system: Milwaukee uses M18 (heavier, more power) and M12 (lighter, less power). If you already own M18 tools, stick with that platform for battery compatibility and longer runtime.
Motor type: FUEL brushless motors are more efficient and powerful than brushed models. All current Milwaukee circular saws are brushless, which is a major advantage for runtime and durability.
Weight: Rear-handle saws are heavier but offer better balance for straight cuts. Sidewinders are lighter and more versatile for overhead work. Consider your typical usage before choosing.
Mistakes to avoid
Buying too much saw: A rear-handle 7-1/4" saw is overkill for cutting plywood and trim. Match the saw to your most common task to avoid unnecessary weight and expense.
Ignoring the battery: Using an older M18 battery on a FUEL saw can limit performance. High Output batteries (HD12.0 or HD8.0) are recommended for the 2834-20 to unlock full power.
Skipping the blade upgrade: Stock blades are often average. Upgrading to a Diablo or Milwaukee blade improves cut quality and reduces effort significantly.
