If you are looking for a milwaukee electric circular saw, you are probably choosing between a few things at once: how often you will cut, how thick your material is, whether you need a corded tool that never runs out of power, and how much you want to spend on the blade and accessories around it. This guide narrows that down. We compare seven corded Milwaukee circular saws, group them by the jobs they handle best, and explain the specs that actually matter. The selection criteria are blade diameter, cutting depth at 90 and 45 degrees, motor power, blade-change convenience, and the features owners most often mention when describing day-to-day use. Everything here is based on manufacturer specifications and general owner feedback patterns, not on our own bench testing.

Buying Guide
Selection Criteria
When comparing corded Milwaukee circular saws, focus on four things: the blade diameter you need, the cutting depth at both 90 and 45 degrees, the motor and whether it stays strong under load, and the comfort of the tool for your typical cut. Brand reputation and owner feedback patterns help too, because they reveal how a saw holds up after months of use rather than on day one.
Important Features
- Blade diameter: 7-1/4 inch is the common standard for framing and general cutting.
- Motor type: Inline, sidewinder and worm drive layouts each handle torque and visibility differently.
- Base and shoe: A stable base keeps cuts square, especially on sheet goods.
- Bevel and depth adjustment: Easy, repeatable adjustments save time on repetitive work.
- Blade guard and arbor: Smooth guard action and a standard arbor make blade changes simpler.
Specs to Check
Check the maximum cutting depth at 90 degrees and at 45 degrees. Manufacturers list these numbers, and they matter more than blade diameter alone, because a 7-1/4 inch blade does not cut the same depth in every saw. Also check amperage or motor rating if you cut dense hardwood or thick stock, and confirm the arbor size so your blades fit.
Choosing by Need
- General framing and homeowner use: The 6390-21 or 6370-21 covers most jobs without extra complexity.
- Long rip cuts and heavy timber: The 6392-21 worm drive is designed for torque under load.
- Sidewinder preference: The 6391-21 gives you a clear view of the cut line.
- Repeat sheet-goods work: The 6377-21 offers the base and adjustment features suited to production cuts.
- Lighter, all-day handheld cutting: The 6358-20 reduces fatigue during long days.
Things to Watch Out For
Do not assume a bigger motor always means a better saw for your work. Heavier tools can tire you out, and oversized saws can be hard to control on small cuts. Always keep the blade guard working properly, unplug the saw before changing blades, and use the correct blade for the material. Refer to the owner’s manual for specific safety instructions, and consult a professional if you are unsure about a particular cut.

FAQ
What is the difference between a sidewinder and an inline circular saw?
A sidewinder places the motor beside the blade, which gives a clearer view of the cut line and is often preferred for long rip cuts. An inline saw places the motor behind the blade, which is the more common layout and feels familiar to many users.
When should I choose a worm drive saw?
Choose a worm drive when you cut thick or dense lumber, make long rip cuts, or need steady torque under heavy load. The gearing is more demanding on the body and the saw is heavier, so it is less suited to light, all-day trim work.
What blade size is standard for a Milwaukee corded circular saw?
A 7-1/4 inch blade is the most common size for framing and general-purpose corded saws. Always confirm the blade diameter and arbor size listed in the manufacturer’s specifications before buying replacement blades.
How do I choose the right blade for my cut?
Match the tooth count to the material. Fewer teeth cut faster in lumber and rough work, while higher tooth counts give smoother finishes in plywood and trim. Check the blade’s packaging or the saw’s manual for recommended uses.
How do I change a circular saw blade safely?
Unplug the saw, wear gloves, lock the arbor if the saw has a lock button, and loosen the arbor bolt in the direction the manual specifies. Install the new blade with the teeth pointing in the direction of rotation shown on the saw, then retighten securely.
Do corded saws need maintenance?
Yes. Keep vents clear of sawdust, inspect the power cord for damage, keep the blade guard moving freely, and check the base for wear. Refer to the owner’s manual for lubrication and service intervals.
Should I consider a cordless saw instead?
Cordless saws offer freedom from outlets and extension cords, but corded saws provide steady power without battery limits. If you cut for long periods or use the saw in remote areas, weigh battery runtime against the convenience of a cord.
Conclusion
For general framing and everyday homeowner cutting, the 6390-21 and 6370-21 cover most needs with simple, dependable designs. If you prefer a sidewinder layout for long rip cuts, the 6391-21 is the model to compare. Heavy timber and torque-intensive work point to the 6392-21 worm drive, while the 6355-20 suits shop users who need extra motor power. The 6377-21 fits production sheet-goods cutting, and the 6358-20 is the better pick for lighter, all-day handheld work. Match the saw to your most common cut, confirm the depth specs for that material, and check the owner’s manual before you start.
