Bosch's GDS 18V-1000 is a half inch high torque impact wrench from its BITURBO range, which pairs a brushless motor with ProCORE18V batteries for corded level output. It lists 1,000 Nm of tightening torque and up to 1,600 Nm of breakaway torque, and it is sold as a bare tool. It suits mechanics, fitters and site trades already on the Bosch 18 V system.

Our take
Torque and speed settings
Bosch quotes a tightening torque of 1,000 Nm and a breakaway torque of up to 1,600 Nm, which puts it in the high torque class just below the DeWalt DCF900. Three speed and torque settings are listed to give controlled power for different jobs, from running down smaller nuts to cracking large ones.
The specs give a no load speed of 1,750 rpm and a half inch square drive.
BITURBO and battery choice
The listing points to ProCORE18V batteries as the way to get full performance from the BITURBO motor. A small 2.0 Ah pack will run the tool, but it will not deliver the same output under heavy load. If you already own larger ProCORE packs from other Bosch tools, this wrench will make good use of them.
What arrives in the box
This listing is a bare tool in a cardboard box with a ladder clip. There is no battery, charger or case. The ladder clip is a small but useful touch for hanging the wrench on a rung or belt while working at height. The listing does not say whether the anvil uses a hog ring, friction ring or detent pin, so check that against your sockets.
Alternatives worth weighing
The DeWalt DCF900P2T offers more breakaway torque and comes as a full kit with batteries and a TSTAK case. The HiKOKI WR36DE lists 1,050 Nm of nut busting torque with IP56 protection. For lighter vehicle work, a compact model like the HiKOKI WR36DH or Makita DTW300 is easier to handle.
Who it does not suit
Anyone without Bosch 18 V batteries faces the extra cost of packs and a charger, which can make a full kit from another brand better value. Home users who only swap wheels a few times a year will also find this more tool than they need.
Verdict
The GDS 18V-1000 is a strong bare tool for Bosch 18 V users who need high torque in a half inch wrench with three settings. If you need batteries included, the DeWalt DCF900P2T kit is the simpler buy, and for outdoor work in poor weather the HiKOKI WR36DE with IP56 sealing is worth a look.
