The different types of circular saws

The different names can seem confusing, but it really all comes down to what you're cutting and where you're going to be cutting it.

Corded vs cordless circular saws

Like most power tools, you'll find corded and cordless. A cordless circular saw gives you portability and the convenience of not having to be next to a plug socket, while a corded one gives you reliable power.

Compact circular saws

Compact circular saws (A.K.A mini circular saws) are exactly what you'd expect - they're lightweight and affordable circular saws that are perfect for light DIY use. After all, there is no point in spending loads on a saw you're only going to use occasionally.

Larger circular saws

Need a more heavy-duty tool? Take a look at the rest of the circular saws in the OnBuy range to find one powerful enough. Filter by voltage: the higher the voltage, generally the more powerful it will be.

Another factor to consider is the size of the circular saw blade - again, the bigger the blade, the thicker the block of wood it will cut through. Here's a rough guide:

  • Blade diameter: 170mm/ Cut depth: 55mm
  • 185mm/ 60mm
  • 190mm/ 65mm
  • 23mm/85mm
