Reversible Internal Spline Drive Tools

Our range of reversible internal spline drive tools is built for applications where precision, speed, and flexibility are essential. Widely used in aerospace assembly and maintenance, these tools are ideal for installing and removing Hi-Lok, Jo-Bolt, and similar collar-driven fasteners with consistent accuracy.

Reversible spline drive tools are engineered for demanding environments, featuring a 0.8 HP motor for excellent stall resistance, fully caged gears with needle bearings for long-term reliability, and a ported throttle valve for smooth, responsive control. The forward and reverse functionality allows technicians to install, adjust, or remove fasteners quickly without changing tools, improving workflow and efficiency.

Compact and lightweight, these tools are well suited to confined working areas such as airframes, engine bays, and structural assemblies. A range of RPM options ensures you can match the tool to your application, whether you need controlled torque or higher-speed fastening in production settings.
