TONE Electric Cordless Nutrunner (CNR Series)

Five cordless torque tools spanning 150–2,100 N·m, with square drive, HiKOKI Multi-Volt battery platform, ±5% repeat accuracy, and automatic shut-off.

More Information

The TONE CNR Nutrunner Series delivers fully cordless, torque-controlled bolting via square drive, so there’s no power outlet and no external controller to manage. Five models cover 150 to 2,100 N·m, all running on the HiKOKI Multi-Volt battery platform with a 40-minute charge time.

In addition, a brushless DC motor, automatic torque shut-off, and ±5% repeat accuracy suit structural and civil bolting on sites without mains power. Each unit is supplied with output adapter, L-shaped reaction bar, battery, charger, and metal case.

How Cordless Torque Control Works

This cordless design is the counterpart to the brand’s lever-socket tool. Both are built for the same torque-regulated structural and civil applications; however, this version uses a square drive that accepts standard impact sockets instead.

The torque controller is integrated directly into the tool body, and automatic shut-off stops the tool the moment the preset torque is reached. As a result, fastening stays consistent and repeatable regardless of operator technique, even in locations where mains power isn’t available or practical.

Furthermore, all five models run on the HiKOKI Multi-Volt battery platform (BSL 36B18 / BSL 36A18), with a 40-minute charge time. Since the square drive accepts standard impact sockets across the ¾” and 1″ ranges, it’s straightforward to deploy on sites already running impact socket inventory.

Key Features

  • Fully cordless — no power outlet required; work anywhere on site.
  • Square drive — accepts standard impact sockets; ¾” for the smaller models, 1″ for the larger ones.
  • Integrated torque controller — no external control box; clean tool body.
  • Automatic shut-off — stops precisely at the preset torque value every time.
  • Brushless DC motor — efficient, durable, and low-maintenance across the full torque range.
  • Bidirectional operation — full torque control for both tightening and loosening.
  • ±5% repeat tightening accuracy — consistent results under uniform conditions across all models.
  • Digitorqon compatible — supports an optional DTM digital torque verification attachment.
  • HiKOKI Multi-Volt battery platform — 40-minute charge time; compatible with BSL 36B18 and BSL 36A18 batteries.

Typical Applications

  • Structural steelwork and high-tension bolt installation
  • Bridge and civil infrastructure construction
  • Road construction and barrier systems
  • Rail and railway infrastructure
  • Remote or elevated worksites without reliable mains power access
  • Industrial plant maintenance
