How to use a Worx circular saw

Updated: October 2026

The pencil line drifts and the blade starts to bind. How to use a Worx circular saw, on these five listings, is a depth set just past the timber, an offcut that can fall, and a stop when the line moves. Forcing the saw back onto the line is how these cuts kick. Which model to buy stays on the [Worx circular saw comparison](/hub/power-saws/worx-circular-saw). Kit versus bare stays on the [Worx circular saw buying guide](/hub/power-saws/worx-circular-saw/sub/worx-circular-saw-buying-guide). Products Compared drew these steps from Electrical Safety First, Homebuilding's UK guides and the amazon.co.uk notes, on 16 October 2026. We did not run a lab cut.

Set the depth before the battery goes on

Take the battery off before you touch the depth lock or the guard. Electrical Safety First asks you to check that the retracting guard moves freely with the tool disconnected, and to put on eye protection before the first cut. Homebuilding's rule of thumb is about 3 mm past the material. That 3 mm is their advice, not a Worx specification. On 18 mm plywood the teeth should just clear the underside. The kit bullets state 41 mm at 90 degrees. If the stock is thicker than the listing states, the method will not add millimetres. The Nitro item type states 65 mm, a different saw, on Worx WX531 vs WX520.

Support the sheet and stand to the side

Support the work so the waste can drop clear. If the offcut is trapped, the kerf closes on the blade and the saw climbs. Two trestles under a full sheet, with the cut line just beyond the support, are the ordinary setup. Electrical Safety First says to stand to one side of the blade, out of the kickback line. Both hands stay on the saw. Ease the feed when a compact review would have stalled. A brake is named on Amazon only for the WX530.9. Do not assume the other four stop the moment you release the trigger. Wait until the blade has stopped before you set the saw down.

A straight edge, then stop if the line moves

A freehand line on a long sheet wanders. Clamp a batten, or use a factory edge of ply, and keep the shoe against it. Homebuilding reserves the rip guide for a narrow rip. In this set that guide is named only on the Nitro body, B08BCKXP7K. If the line leaves the pencil mark, stop, let the blade stop, and start again from the waste side. Twisting the saw back onto the line is the kickback move. ExacTrack uses a straight edge you supply. Those steps are on the Worx ExacTrack circular saw page.

Case, hex key and dust

WX531 kit reviews say the case will not close with the blade fitted, so the blade comes off before the saw goes away. A missing hex key on either compact ASIN is a short delivery, not a prompt to jam a screwdriver into the arbor. Section 22 of the Consumer Rights Act 2015 gives 30 days to reject goods that do not conform. A vacuum is not in any box. At home, use the port if you have a hose, and wear a dust mask. At work, HSE wood-dust limits of 3 mg/m³ hardwood and 5 mg/m³ softwood are the employer's duty. Stop for structural timber if the remaining section is unclear, for a saw that burns or will not restart, for chasing cable or pipe, and for any cut you cannot abandon.

Common questions

How far should the blade stick out below the sheet?
Homebuilding's guide says about 3 mm past the material. Label that as their rule of thumb. On 18 mm ply the teeth should just clear the underside. The compact listing depth is 41 mm at 90 degrees on the kit bullets, so the limit is the timber, not how far you wind the lock.
How do I keep a long cut straight without ExacTrack?
Clamp a straight batten, or use a factory edge of ply, and keep the shoe against it. Homebuilding reserves the rip guide for narrow rips. In this comparison that guide is named only on the Nitro included line. A freehand line on a full sheet is where these reviews wander.
What do I do if the saw starts to wander?
Stop, and let the blade stop before you lift the saw. Do not twist it back onto the pencil line. Start again from the waste side with the support still holding the sheet. Electrical Safety First treats forcing a wandering cut as the kickback mistake.
Where do I stand, and when do I check the guard?
Stand to the side of the blade, not behind it. Check that the guard retracts with the battery off, before you fit the pack. Eye protection goes on before the trigger. Both hands stay on the saw while it is cutting.
Why will the WX531 not go back in the case?
UK reviews of the kit say the case will not close with the blade fitted, so the blade comes off for storage. Plan for that before you pack up. It is not a fault you fix by forcing the lid onto the teeth.
The hex key is missing. Can I still change the blade?
Not safely with a substitute. Missing Allen keys are a repeated review on both compact ASINs. Reject the short delivery within 30 days under the Consumer Rights Act 2015, section 22, and wait for the key that matches the arbor.
When should I stop and call someone else?
Call a professional for structural timber when you cannot tell what the remaining section is doing, for a saw that burns or dies and will not restart, for chasing cable or pipe, and for a job you cannot stop. A wandering DIY line you can restart is still your cut. A joist you are not sure about is not.
