Cordless models dominate this guide because they meet the needs of most users today. But pneumatic still holds a real place in equipped professional garages.
When pneumatic still has its place: In a garage with a permanent central compressed air network, for very long sessions without interruption, or for mechanics who want the maximum lightness and constant power of an air tool. Pneumatic never runs out of battery.
When cordless is clearly superior: For mobility, on construction sites, in a garage without a central compressor, for professionals who travel from site to site, or for anyone who already has a fleet of 18V/20V batteries.
| Model | Drive | Type | Price CAD | Best for |
|---|---|---|---|---|
| Chicago Pneumatic CP-734H | 1/2'' | Pneumatic | $287 | Fixed garage, general auto mechanics |
| Chicago Pneumatic PG87 Stubby | 1/2'' | Compact pneumatic | $280 | Confined spaces, engine compartments |
| Chicago Pneumatic PG87 Heavy Duty | 1/2'' | Pneumatic | $410 | Intensive use, high torque |
| Chicago Pneumatic 3/4'' | 3/4'' | Pneumatic | $774 | Heavy mechanics, heavy trucks |
| JET 400252 | 1/2'' | Pneumatic | $179 | Fixed workshop, tight budget |
The Chicago Pneumatic range deserves special mention: it has been a benchmark in professional mechanical garages in Quebec for decades. For a workshop equipped with a central compressor, CP models offer consistent power, remarkable lightness, and proven durability over thousands of hours of use.
How to choose your cordless impact wrench
Drive size: the most important choice
1/2'' is the universal drive: it covers 90% of applications in automotive mechanics, residential and commercial construction, and general maintenance. If you're only buying one impact wrench, it should be 1/2''. The 3/8'' is more compact and lighter — perfect as a supplementary tool or for applications that don't require much torque. The 3/4'' is reserved for heavy-duty applications: heavy trucks, machinery, industrial equipment. Most automotive mechanics never need it.
Battery platform
The same logic applies as for all cordless tools: if you have DeWalt 20V batteries, choose DeWalt. If you have Makita LXT 18V batteries, choose Makita. If you have Milwaukee M18 batteries, choose Milwaukee. Changing platforms is expensive for batteries. If you're starting from scratch, all three platforms are excellent — DeWalt 20V is the most widespread on Quebec job sites.
Torque: more is not always better
Excessive torque on small bolts can strip them or seize them permanently. That's why adjustable torque modes are important: they allow you to use maximum power when needed and reduce it for delicate applications. All models in this selection have adjustable torque modes — this is non-negotiable for professional use.
Cordless vs. pneumatic: the real question
For mobility and versatility, modern brushless cordless tools are now comparable to pneumatic tools for 95% of common uses. Pneumatic tools retain an advantage for very long sessions in a fixed workshop, for maximum lightness, and truly consistent power. If you already have a central compressor in your garage, the Chicago Pneumatic models in the table above are an excellent complementary option.
Practical tip: For automotive mechanics, invest in a set of impact sockets rather than standard chrome sockets. Standard sockets are not designed to absorb the shocks of an impact wrench and can crack or shatter — a real risk of injury.
