Key Features

This compact circular saw can essentially replace a DIYer's or professional's need for a full-size 7-1/4" circular saw. This saw was born to cut wood, especially 2" nominal lumber materials.
4-1/2" Compact Circular Saw - RK3441K | Rockwell Tools
Rockwell's new Compact Circular Saw with a 4½" blade cuts 2X4s in a single pass, and is about 50% lighter than conventional 7¼" circular saws. Plus, the lightweight compact circular saw's left-handed blade design provides remarkable cut-line visibility. This compact circular saw weighs only 5 lbs, so it is easier to transport and maneuver (especially overhead) than many other compact circular saws. The slim, inline grip design provides great comfort, balance and control.
The saw’s 4-1/2” blade has a kerf that is less than half the thickness of larger 7-1/4 in. circular saw blades. Since the smaller thinner blade of this compact circular saw takes much less effort and motor strain to cut through the material, the 5 amp, 3500 rpm saw can match the performance of full-size circular saws. The compact circular saw’s maximum cutting depth at 90° is 1-11/16” and its bevel capacity at 45° is 1-1/8”.

Frequently Asked Questions

  • Does this come with a battery and charger?

    No, this model does not come with a battery or charger. This is an electric tool.

  • What is the Rockwell 4-1/2” Compact Circular Saw?

    The Rockwell Compact Circular Saw is the easy-to-use, one-handed alternative to big, bulky circular saws. This mini circular saw has a slim, ergonomic design for easy, comfortable, one-handed operation with all the power to handle home and DIY projects. From long rip cuts, to plunge and bevel cuts, the Rockwell Compact Circular Saw is ready to take it on.

  • How is the 4-1/2” Compact Circular Saw different than a typical circular saw?

    Typical circular saws are big, bulky, and require both hands to operate. The Rockwell 4-1/2” Compact Circular Saw is about 50% lighter than typical saws and has an ergonomic slim-line grip for comfort, balance and control – all with only one-handed use! The Compact Circular Saw can even make bevel cuts up to 45 degrees and tackle both straight and beveled plunge cuts. If you’re looking for a versatile saw to add to your toolbox, the Rockwell 4-1/2” Compact Circular Saw is the perfect choice.

  • Is the Rockwell 4-1/2” Compact Circular Saw battery operated or electric?

    The Compact Circular Saw is a 5 Amp electric tool and has a 10-foot cord to give you the reach you need to skip the extension cord.

  • How heavy is the Rockwell Compact Circular Saw?

    The Rockwell 4-1/2” Compact Circular Saw only weighs 5lbs – about 50% lighter than a typical circular saw – making it extremely easy to maneuver with one hand while leaving your other hand for the work. Easy to transport and maneuver, the Compact Circular saw delivers the power you need for a wide variety of projects, with the comfort, balance and control you need in tight or out of the way workspaces.

  • What is the maximum cutting depth for the Compact Circular Saw? What kind of materials can I cut?

    The maximum cutting depth of the Compact Circular Saw at 90 degrees is 1-11/16”. The maximum cutting depth of the Compact Circular Saw at a 45 degree bevel is 1-1/8”.

    The blade determines the type of materials you can cut. The blade included with the Compact Circular Saw is ideal for wood, especially plywood, hardwood flooring, nominal 2” lumber, molding, pegboard, dowels, etc.

  • If the maximum cutting depth is less than 2 inches, how can the Compact Circular Saw handle a 2X4 or 2x8? What is “nominal” 2” lumber?

    By industry standards, nominal 2” lumber is slightly less than a full 2” wide. The Rockwell Compact Circular Saw has a 90 degree maximum cutting depth that will easily handle 2X- lumber.

  • What size blades fit on the Rockwell Compact Circular Saw?

    The blades are 4-1/2” with an arbor of 3/8”.

  • What kind of blades can I use on the Compact Circular Saw?

    Included in the package is a carbide tipped wood blade, but the Compact Circular Saw will accept any standard 4-1/2” saw blade.

  • How long do the blades last?

    The life span of the blades can vary depending on the type of blade and the materials being cut. Here are some guidelines based on typical use:

    Carbide-tipped Wood Blade:

    Cut 600m (1,968.8 ft) of 20mm (3/4") larch/pine

    Cut 600m (1,968.5 ft) of 15mm (5/8") plywood

  • How do I get the blade off?

    First, press the red spindle lock button on the back of the Compact Circular Saw. While holding the button down, use the hex key and turn right to loosen and remove the bolt, washer and blade. Replace the blade, put on the washer, then the bolt and turn left to tighten the blade in place. Release the spindle lock button. When you’re done, there’s even a place to keep your hex key right on the cord of the Compact Circular Saw so you’ll always have it on hand when you need it.

  • What if I misplace the hex key? What size is it?

    The hex key included with the Compact Circular saw is a standard 5mm hex key.

  • How does the Compact Circular Saw’s quick cutting depth adjustment work?

    The quick cutting depth adjustment is designed to be easy to use so you can spend time doing the work that matters. To change the depth adjustment, release the black locking lever, adjust the base plate to the desired depth and lock the lever back in place. Quick and easy.

  • I don’t see any kind of spring for plunge cutting on the Rockwell 4-1/2” Compact Circular Saw. Does this tool make plunge cuts?

    The Compact Circular Saw can plunge cut like a typical circular saw, but does not have the automatic plunge cut feature like the Rockwell VersaCut. For more information about making plunge cuts with the Compact Circular Saw, please refer to the owner’s manual.

  • Does the Compact Circular Saw have a laser guide?

    The Rockwell 4-1/2” Compact Circular Saw does not have a laser light. With the remarkable cut line visibility of the left-handed blade design and the cut line indicator on the base plate, the Compact Circular Saw still helps you make the cut you planned.

  • What size vacuum hose can be attached to the Compact Circular Saw?

    The vacuum adapter directly accommodates a 1-1/4” hose, a common size for most workshop vacuums.

  • I misplaced my manual. Is there anywhere I can get more information?

    You can download the manual here. Our friendly customer service team will be glad to answer any questions you may have at 1-866-514-7625 (ROCK).

Rated 5 out of 5 by from Nice upgrade for my saw collection Have the Versacut which has been great for many jobs, but not made for larger materials like 2x4. This saw takes care of that, and still gives great portability and usability.

Rated 5 out of 5 by from Compact Circular Saw Winning Attributes I bought the 4-1/2" compact circular saw on line and was hoping for great features and attributes from Rockwell. The first attributes was the blade guard ease of mounting and use when cutting; Safety first! the second was the sturdy case and ease of a ergonomic grip; Second part of safe use. The third wonderful feature is the ease of changing the blades which is essential for efficient use in the field. Lastly was the quietness compared to the other vendor's saw I had. Noise is a hazard and also a hindrance to running the saw safely with other in the area.

Rated 5 out of 5 by from Tough enough and easy to control I purchased this saw for a job thinking it would do the job I needed and then I could give it to one of my techs to use. Once I used it, I decided to keep it for myself. Very easy to use and plenty of power. Much faster then using my cordless skill saw. Love. I recommend it!

Rated 5 out of 5 by from A Handy Compact Saw This saw is easy to use, light weight, and has plenty of power. Cutting thru 2x4's is a snap. The only negative is that it can't cut a 45 degree angle thru a 2x4. Other than that it's a great little saw, for the price.

Rated 5 out of 5 by from Ease Of Use I am Senior Female, remodeling daughters house, and this saw is awesome! I bought my saw about 10 months ago, it is light weight, easy to use, cuts anything I would use a circle saw on, and everyone who has tried it, loved it. I just purchased two more for gifts, so mine is not on loan when I need it. Another Great Rockwell tool!!!

Rated 5 out of 5 by from Great Compact Versatile Saw Recently purchased this tool for a project in the attic. There's not much room in the attic and I was tired of lugging around a heavy 7 1/4 inch saw. This lightweight gem was just what I needed. The laser guide works well, has plenty of power and the kit came with five extra blades.

Rated 5 out of 5 by from Best circular saw ever I build dollhouses and this little saw is spectacular for plywood of all thicknesses. Lightweight, straight easy cuts and no splinters or chipping. The only problem is with the safety button. If you have small hands like I do, you have to be a contortionist to hold the safety button in while activating the on button. I solved this problem by putting a small screw in the side of the safety button to hold it in. Really like Rockwell tools and their quality.
Date published: 2017-12-07
Rated 5 out of 5 by from Killer little saw!!! I've been contemplating buying this saw for quite some time. Finally I pulled the trigger. I couldn't be happier! I put it to work immediately. The thin blades blasted through some really heavy wet pressure treated 2x6's with no problem. Love how the blade is on the left side, easier to see what you're doing. The zero mark is spot on. The only thing I don't like is the safety button, kinda awkward, but if that's the only bad thing I can live with that. Keep the awesome tools coming!!!

How to remove a blade bolt that is broken inside. 

Asked by: Richard59
Since it is a reverse thread, an easy out won't work. Try drilling into the broken bolt. The drill bit might spin it out.
