Angle Grinder, Jigsaw or Circular Saw - Which First?
Angle Grinder, Jigsaw or Circular Saw — Which Do You Need First?
The question every DIYer asks after buying their first cordless drill
These three tools are often lumped together as "cutting tools" — but they do completely different jobs. Buying the wrong one for your situation means it sits in the shed gathering dust. Here's how to choose correctly the first time.
for Most DIYers
These three tools look vaguely similar on the shelf — they're all cordless, they all cut things, and they all sit in the same aisle at Bunnings. But they're designed for completely different tasks, different materials, and different skill levels. Getting the wrong one wastes money and sits unused. Here's the straight breakdown.
We'll profile each tool honestly, then give you a simple "what situation = which tool" decision guide so you can walk away knowing exactly what to buy.
An angle grinder spins an abrasive disc at up to 11,000 RPM — far faster than any saw. It's designed primarily for metalwork: cutting rebar, grinding welds, cutting bolts, removing rust, and shaping metal. With the right disc it can also cut tiles, masonry, concrete, and render.
What it is not good at is woodwork. It can technically cut wood but it's dangerous, imprecise, and the wrong tool for the job. Think of it as the tool you reach for when working with hard, tough materials — not timber.
- Cutting metal — rebar, bolts, angle iron, pipes
- Grinding welds and rough metal edges
- Cutting tiles and masonry
- Removing rust and paint from metal surfaces
- Cutting concrete pavers and block
- Tradies and serious renovators
- Cutting timber or sheet wood
- Curved or shaped cuts
- Precision or clean-finish cuts
- Beginners — higher kickback risk
- Indoor fine carpentry
- General home DIY with no metalwork
A jigsaw uses a reciprocating blade to cut up and down rapidly. Its big advantage over every other saw is versatility — it can cut curves, circles, straight lines, irregular shapes, and plunge cuts (starting a cut in the middle of a panel). Swap the blade and it handles timber, MDF, plywood, laminate, metal sheet, plastic, and even ceramic tile.
It's also the safest and most forgiving power saw for beginners. The blade is small, the tool is easy to control, and mistakes are less catastrophic than with a circular saw or angle grinder. This is why experienced DIYers consistently recommend the jigsaw as the best second power tool after a cordless drill.
- Curved and shaped cuts in timber and sheet material
- Cutting holes in benchtops (sinks, powerpoints)
- Plunge cuts starting mid-panel
- Cutting skirting boards and architraves
- Sheet metal, plastic, laminate — blade swap
- Beginners — forgiving and easy to control
- Long, fast straight cuts in thick timber
- Ripping down full sheet boards quickly
- Metal grinding or masonry
- Production or volume cutting
- Very thick hardwood (over 70mm)
- Jobs requiring a perfectly square edge consistently
A circular saw spins a toothed blade at high speed to make fast, straight cuts through timber. It's the tool of choice for framing, decking, and cutting large sheet material to size quickly. Where the jigsaw is flexible and forgiving, the circular saw is fast and powerful — it can rip through a full sheet of plywood in seconds.
However, it takes more skill and setup to use well. Cutting straight lines consistently requires a guide rail or chalk line, and kickback is a real risk if the blade binds. It's the natural step up after a jigsaw for anyone getting into more serious carpentry, decking or renovation work.
- Ripping down sheet timber and plywood quickly
- Cutting decking boards and framing timber
- Cross-cutting structural timber to length
- Renovation and building work
- Repetitive straight cuts at speed
- Anyone doing serious carpentry or decking
- Curved or shaped cuts
- Plunge cuts in panels
- Metalwork or masonry
- Confined spaces or awkward angles
- Beginner first-tool purchase
- Small, detailed or intricate cuts
