Overview
Not a compact stubby for tight engine bays, this is a full size half inch impact built for lug nuts and stuck bolts. A brushless motor drives it, and a three speed setting limits torque on smaller fasteners.
Breakaway torque high enough for seized fasteners, in a kit with battery and charger, makes it a strong choice for home mechanics. The listing gives no weight, RPM or impact rate, which matter for overhead work.
Who it's for
Car owners and DIY mechanics who rotate tires and fight seized hardware. Furniture assembly or small fastener work calls for a lighter impact driver.
Pros and cons
- High breakaway torque
- Three speed control
- Battery, charger and bag included
- Hog ring anvil for quick socket swaps
- Weight not listed
- RPM and impact rate not given
- Sockets not included
Performance notes
Breakaway torque comes from the brushless motor and hammer mechanism delivering repeated blows. The speed setting caps power to avoid overtightening, and battery charge affects how hard it hits on long jobs.
