How to Choose the Best Chainsaw for Your Toolkit

Tired of borrowing your neighbour's power tools whenever you need to clear some wood or take on a landscaping project? Time to add a chainsaw to your toolkit. From choosing between gas chainsaws and electric models to finding the right guide bar length, learn how to choose the best chainsaw for you in our guide.

How to choose a chainsaw

The right chainsaw all depends on your experience and the type of work you plan to do. Whether you want to trim branches or cut firewood, focusing on the bar length, power, and weight can help you find the best chainsaw for you.

Guide bar length

Guide bar length determines the size of wood you can cut. Small chainsaws (6-12”) can handle light pruning, while medium models (14-18”) are ideal for general use. Big saws (20”+) are the go-to option for large trees and best suited for experienced users.

Power

Chainsaw power affects cutting speed and capability. Electric battery chainsaws offer convenience and reduced noise for lighter jobs like cutting branches and firewood cutting. Gas models deliver greater engine power for demanding tasks like felling large trees. Choose the power source based on your workload and environment.

Weight

A longer bar and greater power capability usually mean a heavier machine. Low-weight chainsaws are easier to manoeuvre, making them ideal for beginners or long periods of use. Heavier models provide more power for felling trees and cutting bigger logs, but can cause more user strain.

Chainsaw safety and maintenance

Follow these tips to stay safe and keep your chainsaw in the best condition. For more chainsaw safety info, check out our useful guide.

Wear proper safety gear: Always use gloves, chainsaw chaps, safety glasses, ear muffs, and steel-toe boots when working with a saw.

Check chain tension: Ensure the chain is snug but moves freely; loose chains can derail, while overtight ones cause wear.

Keep the chain sharp: A dull chain increases kickback risk and overworks the motor. Sharpen or replace your saw’s chain regularly.

Use fresh fuel and proper chain oil: For petrol saws, use the correct fuel mix. For all saws, regularly oil the chain to ensure it spins smoothly.

Clean regularly: Remove debris, sawdust, and oil buildup from the chain, bar, and air filter after each use.

Avoid cutting above shoulder height: Keeping your cuts low reduces the chance of losing control or causing injury.

Use both hands firmly: Always maintain a solid grip and stance to prevent kickback accidents.

Store properly: Keep the chainsaw in a dry, secure place, with a chain cover on.

Follow the manufacturer’s manual: Stick to the recommended maintenance schedules and safety instructions for your specific saw model.

Frequently asked questions

What chainsaw brand is the best?

Top chainsaw brands include STIHL, Husqvarna, and Echo. Trade Tested offers affordable yet powerful alternatives to these top brands with our Greenworks and Flash chainsaws, ideal for both professional arborists and home fixer-uppers.

What is the best chainsaw size for all-round use?

For general-purpose cutting, like limbing work, chopping wood, and felling small trees, a 16–18” bar is ideal. It offers enough reach and power for most household and light professional tasks without being too heavy or hard to control.

Is an electric or petrol chainsaw better?

Battery-powered electric chainsaws are quieter, easier to start, and require less maintenance. They’re great for light to medium work like pruning small branches, plus, you can recharge and reuse the battery across multiple compatible tool skins. Gas chainsaws offer extra power and mobility, making them better for heavy-duty tasks like cutting larger logs. Choose based on your workload and environment.

What is the lifespan of a chainsaw?

A well-maintained chainsaw can last 10 years or more. Longevity depends on usage intensity, build quality, and maintenance. Replacing parts such as chains, bars, and filters can further extend lifespan. All Trade Tested chainsaws come with a minimum 12-month warranty for peace of mind.
