Overview
DuraTech's DTOBW09M is a wrench built around a 23 millimeter capacity, with a listed weight of 1.7 kilograms that points to a full-size tool rather than a pocket wrench.
A 23mm jaw or drive capacity puts this in range for larger nuts, bolts, or pipe fittings, and the 1.7kg weight backs that up as a substantial hand tool. The spec sheet does not state whether the capacity is fixed or adjustable, so buyers working with a range of fastener sizes should check that detail before assuming it adjusts.

Who it's for
Works for anyone with a 23mm fastener to turn, such as larger bolts, pipe nuts, or fittings in that size. Not the right pick if you need a small or adjustable range wrench, since the data only confirms one capacity figure.
Pros and cons
- Full 1.7kg weight for real leverage
- Sized for 23mm fasteners
- Not stated whether capacity is fixed or adjustable
- Heavier than a compact wrench, less suited to tight spaces
Performance notes
At 1.7 kilograms, the DTOBW09M carries enough heft to apply real leverage on a 23mm fastener without flexing, which is typical of wrenches built for that size class. Whether the head is a fixed 23mm or opens to that as a maximum is not stated, so fit should be confirmed against the fastener on hand.
