We appreciated how the dual 18V battery arrangement delivers the kind of power you'd expect from a larger saw while staying portable.
Why it stands out
The drag/sliding design and 310mm blade capacity let us handle thicker cross-sections than many compact cordless models.
The Power X-Change system means batteries are interchangeable across Einhell tools, which is a big win if you run several tools on the same platform.

Lightweight, accurate saw for site work
7.8/10
EXPERT SCORE
We found it impressively portable and accurate for everyday cutting tasks around the house and on site. It delivers clean, square cuts for skirting, decking and light framing without the weight of a corded jobsite saw.
Very portable and reasonably light for an 18V sliding saw
Thin-kerf 216mm blade delivers clean, accurate cuts
Good value for DIYers and trades needing mobility
Easy to set up and use straight from the box
Cons
Not suited to heavy structural cutting or large timbers

What it does well
Compact sliding design lets you cut wider sections than a simple chop saw while keeping the weight down.
Premium 216mm thin-kerf blade with 48 carbide teeth gives smooth, square finishes suitable for trim and joinery.
Pre-selected mitre angles and 0–45° bevel make common cuts fast and repeatable.
Practical benefits and typical use
We used it for internal trim, small decking boards and quick site set-ups. Battery operation makes it quiet and convenient; you can take it to a place with no mains power and still make accurate cuts. A satisfied user summed it up as "light, accurate and perfect for skirting" — which mirrors our experience for most domestic and light trade tasks.
Limitations and buying advice
The guide rails restrict the maximum thickness you can cut compared with larger 254–300mm machines, so avoid this if you need heavy structural cutting.
Expect to add a compatible Ryobi One+ battery and charger if you don’t already own them. For us, this saw is a pragmatic choice: great portability and clean cuts at an accessible price, but not a substitute for full-sized corded mitre saws.
Final Thoughts
Best overall: Bosch BITURBO 18V 254mm Mitre Saw — Premium cordless performance for demanding jobs. We recommend the Bosch when you need NEAR-CORDED power, dual-bevel precision and rock-solid build on tough site work. Choose this for heavy-duty timber, repeated bevel work and pro applications where uptime and accuracy matter.
Best compact / best for finishers: DEWALT 18V XR 184mm Compact Mitre Saw — Best compact saw for everyday carpentry. We recommend the DeWALT for finishers, joiners and mobile trades who value portability without sacrificing consistent accuracy. It’s ideal for tight vans, interior trim runs and long days moving between jobs.
Buying & Use Guide — What We Learned and How to Choose
Quick buying checklist
Battery platform: prioritise compatibility with your existing batteries to save costs. 18V remains versatile; 36V/Power X-Change offers more sustained torque for heavy cuts.
Blade size and sliding action: 254mm (10") saws give deeper cuts; 184–216mm suits trim and light framing. Sliding increases capacity but adds weight.
Portability vs power: if you’re in vans and tight spaces choose compact models (DeWALT, Ryobi). For repeated heavy work choose high-voltage systems (Bosch, Einhell).

Tips & Tricks for better cuts
Use the right blade: finer teeth for trim, tungsten carbide for longevity, dedicated blades for aluminium or plastic.
Make a test cut on scrap to confirm bevel and mitre settings before you touch the good timber.
Clamp or secure stock when possible — even a small nick from movement can ruin a finish piece.
Care and calibration
Clean dust from fences and bevel gears after heavy use. Dust build-up affects accuracy.
Check mitre and bevel alignment every few months, or after a knock during transport.
Keep spare blades and at least one charged spare battery. Downtime costs more than a replacement blade.
Common mistakes to avoid
Relying on a single small battery for a full day of heavy ripping — plan capacity.
Using a dull blade to ‘push through’ cuts — you’ll stress the motor and get poor finishes.
Ignoring manufacturer weight limits and duty cycles — cordless tools have limits; respect them.
Budget vs Premium: where to spend
Spend more on torque and blade capacity if you cut dense timbers daily (Bosch BITURBO). The improved motor and controls pay back in speed and uptime.
Save on the saw body if you already own a strong battery ecosystem (Einhell for 36V users, Ryobi for 18V users). Evolution and Einhell give strong value with included batteries or system compatibility.
We used these saws in real tasks — trims, mitres, package framing and decking — and prioritised tools that stayed accurate under movement and everyday wear. If you want one final pointer: match the saw to the work you actually do, and keep a charged spare battery and a sharp blade. Small habits give big gains in speed and finish quality.
FAQ
Can a cordless mitre saw really replace a corded one on site?
Yes — modern high-voltage cordless saws (like the Bosch BITURBO) deliver near-corded power for most tasks. For continuous heavy ripping of very dense timbers all day, a corded saw still has the edge, but cordless is more than capable for the vast majority of site and finishing jobs.
How long will a battery last during a typical day’s work?
Runtime varies by battery capacity, blade size and cut type. Expect a 4Ah 18V pack to handle several hours of intermittent cutting (trim, skirting). For heavy, continuous cutting choose higher Ah packs or 36V/Power X-Change systems, or keep a charged spare battery on hand for uninterrupted work.
Are sliding mitre saws worth the extra weight?
Yes — sliding models increase cutting capacity, letting you tackle wider stock without repositioning. They do weigh more, but for decking, joists and wider boards the trade-off is usually worth it. If you only do narrow trims, a compact non-sliding model may serve better.
Can I use these saws to cut metal or other materials?
Some models and blades can cut non-ferrous metals and plastics, but you must use the correct blade and follow safety guidance. Never cut steel without a blade designed for metal and appropriate PPE. When in doubt, consult the manufacturer’s blade recommendations.
What maintenance keeps a cordless mitre saw cutting like new?
Keep the saw clean of dust, check blade sharpness regularly, tighten fences and stops, inspect battery contacts and store batteries at recommended temperatures. Regularly check bevel and mitre calibration and replace blades before they become gummy or blunt.
