Hart 20 Volt 6.5 Inch Circular Saw Review: A Lightweight Pick for DIY Builders

A compact, sub-6-pound cordless circular saw with easy adjustments and honest trade-offs, aimed squarely at weekend projects rather than heavy-duty trade work.

Introduction

The Hart 20 Volt 6.5 inch Circular Saw is built with a clear audience in mind: the DIYer and weekend warrior who wants a cordless circular saw that just works without fuss. Right out of the box, the first thing that stands out is how light it feels compared with many other circular saws. Hart is not chasing the heavy-duty contractor market here, and that focus shows in both the design and the overall experience.

This review walks through what the saw does well, where it makes compromises, and who should genuinely consider adding it to their workshop.

A Compact, Low-Profile Design

One of the more interesting choices Hart made is the battery placement. Instead of mounting the pack directly below like many circular saws, it sits off to the side, which keeps the saw’s profile low and tidy. The motor housing does not stick out the way it does on many competitors, and even a larger 4Ah battery does not get in the way on the blade side.

Measured out, the saw spans only about 7.5 inches from the motor housing across, with a total height of roughly 10 inches. That packaging gives it the feel of a sub-compact saw, similar in spirit to the compact offerings other brands have been pushing. It makes for an easy-to-handle package, especially for anyone who finds full-size circular saws awkward.

Weight is another strong point. With the smallest Hart battery installed and a standard 24-tooth carbide blade on, the whole saw weighs about 5 pounds 13 ounces, just under six pounds. That is a genuinely low weight that keeps the saw comfortable during longer cutting sessions.

Adjustments That Actually Feel Solid

Bevel and depth adjustments are where this saw genuinely impressed. Setting the saw to a 45 degree angle is simple, with a clear, easy-to-read arrow marking the scale. Once tightened down, the adjustment stays locked in place; even tapping the saw does not knock it out of position, which is not always the case on saws at any price.

Depth adjustment is equally smooth and simple to read. In a real-world check, a one-inch cutting depth setting measured dead-on at exactly one inch, which is excellent calibration work. These are the kinds of touches that make a saw pleasant to live with, and Hart has done a genuinely good job here.

Cutting Accuracy and Real-World Performance

For precision work rather than volume ripping, this saw performs well. It is not the fastest or most powerful circular saw available, and it is clearly not intended to be. The motor is adequate for typical DIY project cuts, and the comfortable grip plus the low weight make it easy to keep a cut line steady.

One notable compromise: the saw has no electric brake. The blade coasts to a stop after the trigger is released, which is a feature many users appreciate on pricier saws. Given the saw’s accessible positioning, it is a forgivable omission, but it is worth knowing before buying.

Another trade-off is build material. There is a fair amount of plastic where metal parts appear on many competing saws. Again, this reflects the saw’s DIY positioning rather than any hidden flaw, but heavy-duty users should look elsewhere.

Who Should Buy This Saw

If you want a circular saw that is lightweight, compact, easy to use, and offers good value, this one fits the brief well. It suits someone making nice, precise cuts on project work rather than tearing through stacks of sheet goods all day. The comfortable grip and Hart’s battery system round out an appealing overall package.

Hart’s broader tool line follows the same philosophy: practical, comfortable tools for people who want to get projects done around the house without paying contractor-grade prices. If that describes you, this saw is an easy recommendation.

Conclusion

The Hart 20 Volt 6.5 inch Circular Saw is a thoughtfully designed DIY tool with excellent adjustments, a compact side-mounted battery layout, and a sub-six-pound weight. The lack of an electric brake and some plastic construction are the main compromises, but for weekend projects and home workshop use, it delivers exactly what its target buyer needs.
