9290-10 1-½” Torque Multiplier 5-Pc Tool Set

True 1:10 Torque Multiplication & Advanced Epicyclic Gearing

The mechanical powertrain of this heavy-duty multiplier delivers safe, non-impact leverage:

• True 1:10 Torque Multiplication Ratio: Engineered with an actual 1:10 input-to-output torque ratio. This true-scaling ratio eliminates complex torque math on the job; simply setting your standard 1/2″ input torque wrench to 400 Nm delivers exactly 4000 Nm of continuous rotational force to the output drive.
• Forged Dura-Chrome-Molybdenum (Cr-Mo) Gears: The internal gear train is forged from structural-grade Chrome-Molybdenum steel and chemically surface-hardened. This premium metallurgy prevents internal gear teeth from warping, chipping, or stripping when subjected to extreme twisting forces.
• Massive 1-1/2″ Output Drive & Integrated 1″ Adapter: At 4000 Nm of torque, smaller drive squares (such as 3/4″ or 1″) face a high risk of rotational shear failure. The 9290-10 utilizes a massive 1-1/2″ male square output to absorb these forces. For immediate workshop compatibility, the set includes a high-capacity 814804 impact reduction adapter (1-1/2″ Female to 1″ Male), allowing seamless connection to standard 1″ industrial impact sockets.

Dual-Reaction Arm Architecture & Tool Control

• Straight and L-Shape Reaction Stabilizers: Includes a long straight reaction lever for parallel surface clamping, and a 90-degree bent L-shape reaction leg to lock onto adjacent wheel lugs or recessed brackets. Both reaction arms mate cleanly with the spline pathways on the multiplier housing, redirecting massive counter-rotational forces safely away from the user.
• Thread-Preserving Manual Torque Delivery: Provides slow, continuous, and highly controlled manual rotation. Unlike aggressive pneumatic impact guns that can cause microscopic stress cracking in high-tensile structural bolts, this planetary multiplier protects thread integrity and ensures precise torque tracking.
