Built For

This tool is suited for light assembly tasks requiring consistent, low-torque fastening. Applications include electronics manufacturing, small component assembly, and any production line where over-tightening or inconsistent torque is unacceptable. The auto-stop feature ensures that fasteners are tightened to the preset torque without operator intervention beyond trigger actuation, reducing rework and improving product quality. Its straight form factor is ideal for inline operations and situations where a pistol grip is impractical.

Construction

The UT8905 features a straight-bodied design with a predominantly black finish. The handle section incorporates a matte, slightly textured black material, likely a composite or rubberized grip, for enhanced handling and vibration dampening. The main body appears to be constructed from a durable, possibly anodized aluminum or high-strength composite, providing a robust yet lightweight housing. The 1/4″ hex chuck is integrated at the front, designed for quick bit changes. The exhaust port is positioned at the front, below the chuck, directing air away from the operator’s hand. The air inlet is located at the rear of the tool, with a swivel connection for hose flexibility. Visible branding and operational information are printed in white on the black body.
