Get higher performance in a smaller package with the SF 4-A22

Compact and robust, Hilti’s high-performance SF 4-A22 is the ideal cordless drill driver for light and medium-duty applications — even when it comes to difficult-to-access jobsite locations. Thanks to a brushless motor, you’ll enjoy increased power and runtime so that you spend more time drilling, driving, cutting and fastening and less time waiting for batteries to charge. You’ll also benefit from a longer, virtually maintenance-free life for your tool.

When it comes to cordless drill drivers, size matters. That’s why we’ve made the SF 4-A22 compact enough to access cramped and difficult-to-reach places on the construction site. Weighing in at just 1.28 kg, the SF 4-A22 is also well-suited for working overhead. In addition, you’ll benefit from a stability-enhancing textured tool grip along with optimal design and placement of switches.

Power without compromise

The SF 4-A22 is powered by a brand-new brushless motor, which improves battery efficiency, delivering great performance in a small, compact body. Brushless technology brings high torque (62 Nm hard-joint and 36 Nm soft-joint) and reduces the need for maintenance due to no carbon brushes. Brushless motors help to reduce friction and enhances the tool's performance, allowing you to get more done in less time. With increased RPMs, the SF 4-A22 is the perfect tool for all your compact-class drilling and driving applications. 

Increased comfort and control

Experience reduced kickback with Active Torque Control

When you choose the SF 4-A22, you can take advantage of Hilti’s Active Torque Control (ATC) system. The ATC helps prevent over-rotation of the tool when a bit binds or sticks, helping reduce the chance of injuries on the jobsite. ATC comes as standard with the SF 4-A22.
