TOHNICHI RTD500CN tua vít định lực 100 ~500 cN·m /1/4″ Hex bit

TOHNICHI Torque Screwdriver

Rotary Slip and Adjustable Torque Driver

Model: RTD500CN ( 100 ~ 500 cN·m, 1/4″ Hex)

• Rotary Slip Mechanism: Once the preset torque is reached, the internal mechanism slips and idles. This makes it impossible for an operator to apply over-torque, ensuring consistent quality. 
• Easy Adjustment Scale: Features an external laser-etched scale. You simply twist the body to align with your target setting and lock it securely into place using the black lock ring. 
• Anti-Roll Design: The handle features a hexagonal locker shape that prevents the driver from rolling off flat workbenches.
• Toggle Clutch Durability: Utilizes Tohnichi’s proprietary toggle clutch torque detection mechanism, enhancing the tool's lifespan and reliability under heavy industrial use. 
• Auxiliary Tightening Support: Features a built-in slot to attach an optional auxiliary tightening handle (sold separately) for easier torque application at the upper 500 cN·m limit

• Torque Range: 100 to 500 cN·m (centinewton-meters)
• Graduation: 5 cN·m increments
• Accuracy: ±3% of the indicated value
• Drive Size: 1/4 inch (6.35 mm) hexagonal socket
• Overall Length: 155 mm
• Weight: 0.27 kg (approx. 0.6 lbs)
