Makita USA has made a significant addition to its cordless power tool lineup with the launch of the XGT cordless shear wrench, model GTW01. This innovative tool is designed to provide steel erectors with a cordless alternative that can rival and even surpass corded tools on the jobsite.
Key Features and Benefits
Performance
The new Makita cordless shear wrench boasts an impressive performance boost. It is advertised as being up to 14% faster than its corded counterpart, allowing for quicker completion of tasks on the jobsite. Additionally, it is 3.5 lbs lighter than the previous 18V LXT system model, reducing user fatigue during extended use.
Design and Safety
Electric Brake: The electric brake ensures quick and precise stopping of the tool, enhancing safety and control during operation.
Metal Gear Housing: The metal gear housing provides durability and strength, ensuring long – term reliability in demanding construction environments.
On – Tool LED Charge Status Indicator: This convenient feature allows users to easily check the battery charge status directly on the tool, minimizing downtime.
Shoulder Strap Hook: The shoulder strap hook provides a comfortable and secure way to carry the tool, especially during long workdays.
Functionality
The bolt tip ejecting lever, located near the power switch, makes tip disposal easier and more efficient. This is a practical feature that saves time and effort during the fastening process.
How Shear Wrenches Work
Shear wrenches are commonly used in metal construction to tighten torsion control bolts. These bolts are designed to provide a secure and precise fastening solution. When the fastener is tightened to its set torque, its head is sheared off, preventing overtightening.
Inner and Outer Sockets
Shear wrenches have inner and outer sockets. The inner socket has a spline profile and engages with the bolt tip, while the outer socket engages with the hex nut. During the tightening process, the outer socket rotates and tightens the nut until the required torque is reached. At the same time, the inner socket builds up reaction torque but does not rotate.
Torque Limit and Bolt Shearing
When the proper torque or tension is reached, the outer socket stops rotating, and the reaction torque rotates the inner socket. The tip of the bolt shears off and is then ejected and discarded. This mechanism ensures that the fastener is tightened to the exact specification, providing a secure and reliable connection.
Comparison with Traditional Drills
With a traditional drill, the reaction torque is exerted on the tool body. If you let go of the drill, or if it jams or binds, the drilling or driving accessory will stop moving, and the tool will rotate. In contrast, with a shear wrench, the reaction torque is generated within the tool and exerted on the inner socket. This design ensures that the outer socket rotates the hex nut, while the inner socket holds the spline steady until the required torque is met. At this point, the shear limit of the spline tip is reached, and it breaks off.
In conclusion, the new Makita XGT cordless shear wrench is a well – designed and innovative tool that offers significant advantages over traditional corded shear wrenches and traditional drills. Its improved performance, enhanced safety features, and practical functionality make it a valuable addition to any steel erector’s toolkit.
