WORX 20V 7.25-in Sliding Compound Miter Saw

Worx Miter Saw

Worx Introduces First 20V Benchtop Miter Saw

The Worx 20V 7-1/4 in. Cordless Sliding Compound Miter Saw might not be the best miter saw for all users. At $299 for the kit, however, it could, however, become the go-to saw for DIYers and anyone looking for something small and truly portable. We could see trim carpenters and deck builders using this tool if they don’t require a more powerful or deeper-cutting solution. At half the weight of a conventional 10-in. miter saw and powered by a 20V battery pack, this aluminum-framed 21-lb. cordless miter saw can go with you to wherever the work is.

Worx WX845L Overview

Though it’s designed for portability, the Worx Sliding Compound Miter Saw has the requisite tools for tackling small home projects in the basement, garage, deck or patio, or off-site. Since it runs on the brand’s 20V battery platform, you can forego the need for a power outlet if you don’t need to make tons of cuts. How many cuts? That’s the question, and we’ll need to get this saw into our shop to answer that further.

With a 3600 RPM no-load speed, this 7-1/4 in. saw cross-cuts 2x4s, 2x8s, crown molding, trim, and window casings. It can most certainly tackle planks and rails for deck building as well as engineered wood flooring.

Worx 20V Cordless Sliding Miter Saw Features

The Worx WX845L 20V miter saw features a unique work hold-down lever on the left side of the fence. It’s designed to secure the workpiece for the duration of the cut—keeping your hands clear of the blade. As an entry-level product, this seems like a really good idea. The two-part adjustable fence system also handles taller stock, like small crown molding. The fence measures just 3-1/4″ tall on the left and 2-1/2 in. tall on the right. It won’t let you do larger standing crown, but it gives you some options.

We also like the included left and right extension wings. They fold up as opposed to sliding in and out during storage and transport.

The Worx Sliding Compound Miter Saw has a maximum 2-1/4″ depth of cut at 90° and 1-5/8″ at a 45-degree bevel. That’s sufficient for 2X material—even when beveling. The miter scale includes the expected positive detent stops from 0-47° left and right. For the occasional dado or rabbet cut, the saw includes a depth stop adjustment. You can also engage the slider’s lock knob for non-sliding miter cuts, or release it for cross-cutting material up to 8.25-inches.

Notably, this inexpensive saw features enclosed, linear ball bearings for smooth and controlled slide operation of the rails.

Special Features and Accessories

The WX845L uses a shadow cut line indicator—our favorite method for finding your exact cut line. On top of that, it also has an LED worklight which helps when cutting indoors. Both features activate via separate switches to help conserve battery life—just don’t forget to turn them off. The D-shaped handle seems designed for both righties and lefties with the trigger built right into the handle.

Lastly, the Worx cordless sliding miter saw comes with a dust bag to keep your workspace tidy. If you have access to a shop vac—which we highly recommend—you can attach the hose to the saw’s 1-5/8″ dust port.

The base of the Work Sliding Compound Miter Saw has four integrated mounting holes to securing it to a workbench or portable miter saw stand.

Pricing and Availability

The Worx 20V Power Share 7-1/4 in. Sliding Compound Miter Saw comes with a 4.0Ah battery, 2-hr charger, 40-tooth carbide-tipped blade, dust bag, and blade key. It retails for $299 as a kit or $229 (WX845L.9) as a bare tool. It includes a 3-year warranty.

You can purchase the Worx WX845L directly from Worx.com, or through online retailers like Amazon.com or Acmetools.com.

Same weight as the Craftsman V20

Neither says Brushless, so if they are both brushed, then this one is about $70 more than the Craftsman.

Unless you have Worx batteries lying around…

At 299, it would be hard to justify this one over the kobalt. I’ve been using my older nimh makita sliding miter for 14 years now, and looking at replacements, I havent found any smaller, light, cordless miter saws that have the capacity and dual bevel capability of the kobalt.

I just recently purchased the 18v Bosch Biturbo 8.5 mitersaw. I have been so impressed with it. Cuts through everything I have thrown at it so far (including purpleheart) without any loss of power. Everything is perfectly flat and square with no flex in the head (tested with a Woodpeckers precision straightedge). I have a 2019 model Kapex in the workshop and a 36v Makita site saw. But the Makita is just so heavy to transport that unless it is a larger contract that will see me on a site for a week or more I would just leave it… Read more »
