Why this one
Four selectable torque steps
Regulate output across four settings — 976, 1300, 1735 and 2712 Nm — so you can match the fastener at hand without reaching for a second tool.
Twin hammer mechanism
The twin hammer design delivers consistent, balanced impacts that transfer energy efficiently into the fastener.
M36 bolt capacity
Sized to handle fasteners up to M36, this tool covers the heavy end of the spectrum that 1/2-inch and 3/4-inch drive air tools simply cannot reach.
Built for shop and field
At 504.5 mm (19.9 in) long and weighing 8183 g, this is a substantial tool designed for leverage and durability in demanding automotive tools applications.
Operator-focused details
Sound level is rated at 104.5 dB and vibration at 12.88 m/s squared, figures you need for workplace exposure planning and compliance.
Read the full description
When the job calls for serious fastener force, this is the tool to reach for. The Teng Tools ARWM11S is a 1-inch drive pneumatic unit built around a twin hammer mechanism and four selectable torque steps that top out at 2712 Nm. It handles fasteners up to M36 and delivers a maximum reverse torque of 2013 ft-lb for breaking stubborn hardware.
The four torque settings — 976, 1300, 1735 and 2712 Nm — let you dial output to the joint. Use the lower steps for snugging large-diameter bolts to a controlled preload, then switch to full power tools capability when you need to crack a corroded flange or frozen axle nut. Free speed is 5500 rpm, keeping cycle times tight on repetitive work.
Physically, the tool measures 504.5 mm (19.9 in) and weighs 8183 g. The straight-body design with a D-handle and auxiliary side grip provides the two-handed control you need when reaction torque is high. Air supply requirements are straightforward: a 1/2-inch inlet, a 3/4-inch minimum hose and 9.6 cfm at continuous duty.
Noise is rated at 104.5 dB and vibration at 12.88 m/s squared — hard numbers that let you plan exposure limits and hearing-protection requirements before the first bolt turns. Bolt capacity reaches M36, covering the heavy fasteners found on mining, agricultural, structural and heavy-transport equipment.
Whether you run a fleet maintenance bay, a heavy-equipment shop or an industrial assembly line, the ARWM11S puts controllable, high-output torque in a straight-body package designed for daily professional use.
