FAQs
What is the fastest subcompact impact driver?
The fastest subcompact impact driver currently available is the Milwaukee M12 Fuel 2553-20, which delivers up to 3,300 RPM and 4,000 IPM. Its brushless motor provides superior speed and efficiency for its size, outperforming many 18V models in lighter applications. The compact 5.1-inch length allows it to fit into extremely tight spaces while maintaining balance and control.
Another excellent contender is the DeWalt Atomic DCF809, offering 2,800 RPM with reliable torque output and a compact, ergonomic frame. These drivers are designed for professionals who need quick fastening performance without the fatigue of a larger tool.
What is the best 12V impact driver?
When it comes to 12V models, the Bosch PS42-02 12V Max EC Brushless Impact Driver stands out as the best. It delivers 975 in-lbs of torque and 2,600 RPM, making it surprisingly powerful for its size. Its lightweight, well-balanced design makes it perfect for electricians, cabinet installers, and maintenance techs who work in confined areas.
Close behind is the Milwaukee M12 Fuel 2553-22, offering top-tier power, compactness, and battery efficiency. Both models use brushless motors, ensuring longer lifespan and smoother operation under load.
What impact is better, 1/2 or 3/8?
It depends on the job. A 1/2-inch impact driver is better for heavy-duty tasks like loosening lug nuts, suspension work, or large fasteners—it provides more torque and can handle higher load applications. Meanwhile, a 3/8-inch impact driver is more compact and versatile, ideal for automotive repairs, light assembly, or precision fastening.
If you frequently work on cars or machinery, you might keep both on hand: the 1/2-inch for stubborn bolts and the 3/8-inch for everyday tasks.
