Circular Saw Buying Guide: Choosing Your Perfect Saw

Circular saws are workhorses for cutting sheet materials and timber. Here's how to choose the right one for your needs.

Blade Size Options

• 165mm (6-1/2"): Compact, cuts up to 55mm, good for sheet work
• 184/185mm (7-1/4"): Most popular, cuts up to 65mm
• 190mm: Standard size in UK, versatile
• 235mm (9-1/4"): Deeper cuts for heavy timber

Key Features

What separates good saws from basic ones:

• Blade visibility: See the cut line clearly
• Base quality: Flat, sturdy base plates
• Depth adjustment: Easy to set accurately
• Bevel capacity: Most go to 45 degrees
• Dust extraction: Port for collection

Corded vs Cordless

Cordless circular saws have improved dramatically:

• DeWalt and Makita offer professional performance
• No cables means safer site work
• Battery weight balances the tool differently
• For continuous sheet work, corded may still edge ahead

Blade Selection

The blade affects cut quality more than the saw:

• 24-tooth: Fast ripping
• 40-tooth: General purpose
• 60-tooth: Fine crosscuts
• Thin kerf: Less material removal, easier on batteries

Safety Considerations

• Always use the blade guard
• Check blade is secure before each use
• Support material to prevent binding
• Cut on the waste side of the line
• Let the blade stop before setting down

Track/Plunge Saws

For precision work, consider track saws:

• Plunge action starts cut in material
• Guided by track for straight cuts
• Cleaner cuts than freehand circular saws
• Essential for worktop and panel work

Making Accurate Cuts

• Mark clearly with knife or pencil
• Use a straight edge for long cuts
• Cut with good face down (tearout is on top)
• Let the saw reach full speed before cutting
