Circular Saws
Last updated: June 14, 2026
Stop ruining your expensive timber with a hand saw like it is the Victorian era. If you want straight lines, clean edges, and a job finished before the pub opens, you need a proper circular saw. I have tested the latest 2026 models to separate the professional-grade beasts from the plastic junk that will fail the moment it sees a piece of hardwood.

Dewalt DWS520KT with Guide Rail
π Best for Precision Joinery
A corded plunge saw that treats timber like butter, provided you do not mind being tethered to a socket.

Reasons to buy
- βParallel plunge action allows for incredibly smooth entries into the workpiece
- βThe included guide rail is straight as a die and stays put without clamps
- βDust extraction is actually effective rather than just a decorative pipe
What will annoy you (The brutal truth)

Bosch Sirkelsag sirkelsag gks 18v-57-2 gx

Reasons to buy

Bosch GKS 85 G
π Best for Heavy Duty Timber
A monster of a saw designed for deep cuts and thick hardwoods that would stall lesser machines.
When you need to rip through 85mm of solid oak, stop playing with toys and buy this corded brute.
Reasons to buy

- βCompatible with the FSN guide rail system for surprisingly straight long cuts
- βThe base plate is thick aluminium and won't warp if you drop it off a workbench
What will annoy you (The brutal truth)
- βThe noise level is genuinely antisocial; your neighbours will hate you within ten minutes
- βThe sheer size makes it overkill and cumbersome for simple sheet material work

If you are just cutting some decking or shelving in your flat, this is all the saw you actually need.

Ask the Community βHow to Choose a Saw That Won't Let You Down
Buying a circular saw is not just about the price tag; it is about making sure you don't end up with a glorified paperweight after three months of use.
Corded vs Cordless
In 2026, cordless saws are nearly as powerful as corded ones, but they are expensive. If you are working in a workshop or a flat with plenty of sockets, stick to corded. You get consistent power and you won't be waiting for batteries to charge. If you are on a roof or a new build site, cordless is the only way to go.
Blade Diameter and Cut Depth
Do not just look at the motor wattage. Check the maximum cut depth at 90 degrees. A 165mm blade is fine for sheet materials, but if you are cutting thick joists, you will want a 190mm or even a 235mm blade like the Bosch GKS 85 G. Always check if the saw can handle the thickness of the timber you use most often.
Rail Compatibility
If you want to cut straight lines without a struggle, look for a saw that is 'rail compatible'. Using a guide rail turns a standard circular saw into a precision instrument. It is the difference between a kitchen worktop that fits perfectly and one that needs a gallon of filler.
Frequently Asked Questions
Can I use a wood blade to cut aluminium?
Only if you want to ruin the blade and potentially injure yourself. Use a dedicated multi-material or aluminium blade with the correct tooth count and rake angle.
Why is my saw burning the wood?
Your blade is either blunt, dirty with resin, or you are using a blade with too many teeth for a rip cut. Switch to a blade with fewer teeth for faster, cooler cuts along the grain.
Do I really need a brushless motor?
If you are a professional using the tool every day, yes. They are more efficient and have no brushes to replace. For occasional DIY use, a brushed motor is perfectly adequate and much cheaper.
