NTD120CN Preset Torque Screwdriver, 40-120 cN.m

Type: Preset Non-Rotary Click Type Torque Screwdriver

Torque Range:

• S.I.: 40–120 cN·m
• Metric: 4–12 kgf·cm
• American: 3.5–10.6 lbf·in

Accuracy: ±3% of the set torque value

Drive Size: 1/4" Hex (6.35 mm, accepts standard E 6.3 hex bits, sold separately)

Applicable Screws:

• Small Screw: M3–M4
• Tapping Screw: M2.6–M3

Dimensions:

• Overall Length (L'): 110 mm
• Grip Diameter (D1): 26 mm
• Body Diameter (D4): 11 mm

• L2: 75 mm

Weight: 0.09 kg

Adjusting Tool: Requires Tohnichi #42 Adjusting Tool (sold separately) for torque setting

Features:

• Preset torque mechanism with no external scale, preventing unauthorized adjustments.
• Non-rotary slip mechanism: Provides a “click” and slight spring-back to signal torque achievement; additional torque may be applied if turning continues, unlike rotary slip models (e.g., RNTD).
• Tohnichi’s toggle clutch torque mechanism enhances reliability and durability.
• Compact and lightweight design for precision tasks in confined spaces.
• Clockwise operation only (counterclockwise tightening model available upon request).
• Compliant with ISO 6789 Type II Class E standards for global use.

Applications: Ideal for repetitive tightening tasks in mass production and maintenance, especially for small screws in electronics, precision instruments, or assembly lines.

Notes:

• Requires a torque tester (e.g., TDT3/TDT3-G, TCC2/TCC2-G) for setting the preset torque.
• Standard bits are not included; compatible with commercially available 1/4" hex bits.
