Sunex Tools 3/4″ Drive Magnesium Composite Impact Wrench (SX3402)

Sunex Tools 3/4″ Drive Magnesium Composite Impact Wrench (SX3402) is a specialized pneumatic tool engineered for high-torque applications where weight and efficiency are critical factors. By utilizing a magnesium alloy clutch housing, this tool achieves a power-to-weight ratio of 358 ft-lb/lb, providing the mechanical force required for heavy-duty vehicle and industrial maintenance while minimizing the physical strain on the operator. The tool is designed for high-stress fastening tasks with a breakaway torque of 2,400 ft-lbs and a consistent working torque of 1,600 ft-lbs.

Key Features and Benefits:

• High Power-to-Weight Ratio: Delivers 2,400 ft-lbs of breakaway torque while weighing only 6.7 lbs, reducing user fatigue during repetitive tasks.
• Magnesium Alloy Construction: The clutch housing uses magnesium to improve heat dissipation and provide resistance to corrosion and physical impact.
• 7-Blade Rotor System: Spring-loaded blades ensure the motor starts quickly and maintains smooth, continuous power delivery for better efficiency.
• One-Handed Control: The combined forward/reverse and power regulator allows the operator to change settings without needing a second hand.
• Maneuverability: The 360-degree rotating air inlet keeps the air hose from twisting, allowing for easier access to fasteners in restricted spaces.
• Noise Management: Designed to operate at 97.6 dBA, providing a lower sound profile than many traditional 3/4″ impact wrenches.

Specifications:

• Drive Size: 3/4″
• Breakaway Torque: 2,400 ft-lbs
• Working Torque: 1,600 ft-lbs
• Free Speed: 6,500 RPM
• Weight: 6.7 lbs
• Sound Level: 97.6 dBA
• Housing Material: Magnesium Alloy
• Handle Material: 40% Glass-Filled Nylon
• What’s Included: Sunex SX3402 3/4″ Impact Wrench, User Manual

How to Use:

• Air Supply Preparation: Connect the tool to a filtered and lubricated air supply. For maximum torque, ensure the air hose has a minimum internal diameter of 3/8″ or 1/2″.
• Lubrication: Add 2Ð3 drops of air tool oil into the air inlet daily before use if an inline lubricator is not present.
• Socket Attachment: Securely fit a 3/4″ drive impact-rated socket onto the anvil.
• Direction/Torque Selection: Use the one-hand switch regulator to select the desired direction (forward or reverse) and the appropriate power setting for the task.
• Operation: Position the socket squarely on the fastener. Squeeze the trigger to begin impacting.
• Storage: Disconnect the air line after use and store in a dry environment to prevent internal corrosion.

Benefits of Using Sunex Tools 3/4″ Drive Magnesium Composite Impact Wrench (SX3402):

• Ergonomic Advantage: The lightest tool in its class at 6.7 lbs, allowing for longer periods of use without arm and shoulder fatigue.
• Efficient Air Usage: The 7-blade rotor design increases the efficiency of air usage, resulting in consistent performance on stubborn or rusted bolts.
• Cool Operation: Magnesium housing ensures the tool runs cooler, extending the life of internal components during high-load operations.

Features:

• Precision-Machined 7-Blade Rotor: Provides high-speed airflow for better torque delivery.
• Internal Magnesium Clutch Housing: Optimizes thermal management for extended tool life.
• 360-Degree Swivel Air Inlet: Prevents hose binding and kinking for better maneuverability.
• High-Impact 40% Glass-Filled Nylon Handle: Resistant to impact and chemical exposure.
• Integrated Variable Speed Trigger: Allows for precise fastener starting and control.
• Twin Hammer Impact Mechanism: Ensures high-torque output for demanding tasks.
• One-Handed Directional and Power Adjustment Toggle: Facilitates quick setting changes.
• Non-Slip Ergonomic Grip Pattern: Enhances handling stability, especially in oily conditions.
