We've shipped over 800 of these this year, mainly to high-rise projects and bridge sites, and the 600N.M torque holds steady even on D40 rebar—most crews find manual wrenches just can't match that consistency on a full shift.
It runs on 220V/50Hz, motor kicks in with automatic torque stop, so what it does is cut power once preset values hit, basically eliminating overtightening or loose joints (which we've seen cause rework on site).
The gear housing is carbon steel with a titanized surfce—holds up better than standerd painted units against job site scrapes—weighs in at 15kg or so, so you'll want two hands for overhead work.
Titanizing isn't common at this price level for torque tools; most budget units just get a spray coat, but it's what gives this wrench decent corrosion resistance on wet slabs.
4-6 weeks lead time typically, maybe 30 days, but confirm before ordering—we usually have stock, but large custom batches (say, with a different plug type) need advance notice.
Not ideal for tight corner work, honestly—teh body is bulky, so for confined column ties a cordless ratchet might be better.
