Bosch GST 18V-125 B: 4 stage orbital and speed selection

Orbital action and speed

Four stage orbital action lets you choose between fast cutting and clean cutting. At the highest setting the blade moves forward on the up stroke to clear material quickly, which suits rough cuts in softwood. At zero it cuts straight up and down for a neat edge in laminate or plywood.

The listing also mentions a speed selection feature, so you can slow the stroke rate down for metal and plastics, which can melt or chatter when cut at full speed.

Motor and weight

Bosch describes the brushless motor as delivering outstanding performance. The listing gives a weight of 1.95 kg, a little lighter than the GST 18V-155 BC and the DeWalt DCS335N. The specs mention a 125 mm figure, which matches the model name and likely refers to cutting depth in wood, although the listing does not say so directly.

In the box

Bosch supplies one T 144 D Speed for Wood blade, a splinter guard and a dust extraction set. The splinter guard helps keep laminate and veneer edges clean, and the extraction set lets you connect a vacuum. No battery or charger is included.

What it leaves out

The listing does not describe blade guidance or a dust blower, and it does not state the handle style. For precise square edges in thick material, the GST 18V-155 BC with its blade guidance is the safer choice. The Metabo STA 18 LTX 150 BL lists low lying blade guidance and comes in a case with three blades.

Who it suits

Bosch 18 V owners who need a general purpose jigsaw for shelving, cut outs and the occasional curve will find this a sensible, lighter option. Heavy users cutting worktops every day may prefer the 155 BC.
