Best Bosch Professional jigsaw

Updated: 21 October 2026

You want one blue GST for a job you can describe. The best Bosch Professional jigsaw depends on the packs you own and the thickness you cut. An 18 V owner who wants that deeper cut without a case looks at the cardboard GST 18V-125 B. Sheet and kitchen cut-outs, with a 12 V pack, point at the GST 12V-70 carton. A buyer who will not start a battery system looks at the corded GST 90 BE. The [Bosch professional jigsaw comparison](/hub/power-saws/bosch-professional-jigsaw) keeps every price and score. Products Compared used those listings and the review notes, not a lab, on 19 October 2026. A qualifying purchase can earn a commission at no extra cost to you.

Best depends on the job, not the stars

The GST 18V-125 S in an L-BOXX is £207.12 and 4.8 from 331 ratings, the highest star line here. The GST 12V-70 carton is £106.99 and 4.5 from 1,998 reviews. Bosch’s UK pages put the 125 mm class at 125 mm in wood and the 12 V-70 at 70 mm. Those facts cannot elect one winner. A 4.8 on a barrel-grip body is a weak default if you are left-handed, if you need shoe detents, or if you still have to buy a battery. Pick by depth, by the battery you can already clip on, and by the handle the title prints. The checks are the buying guide.

If you already own 18 V packs

The cardboard GST 18V-125 B at £179.98 is the pick when those packs fit and you want the deeper class without the case premium. The bullets state a brushless motor and four-stage orbital action, the angle cell says 45 degrees, and the box is a T 144 D, a splinter guard and a dust set. It is 4.7 from 204 ratings, the same pool as the L-BOXX listing at £223.32. Pay the extra when you want the case and a title that says bow handle. The cardboard title does not say bow. Choose the S at £207.12 when curves matter more than a trigger in a bow. How the hand sits is the grip page.

If the work is sheet and cut-outs

The GST 12V-70 carton at £106.99 is the pick for kitchen panels, trim and openings in fitted cupboards, and only if a 12 V pack is already yours. The title states 70 mm in wood. The switch is a slide, which left-handed reviewers find awkward, and there is no dust blower. Skip it for thick timber and for anyone who would have to buy the battery to make £106.99 true. The L-BOXX GST 12V-70 at £128.25 states SDS blade change and an LED, at 4.6 from 2,187 reviews, and reviewers still say there is no blower. The other routes are on the voltage page.

If you do not want a battery system

The GST 90 BE at £129.31 is the pick when the socket is the power supply. The bullets state 650 W, a bow handle, SDS blade change, bevel cuts, a blower and orbital action. There is no LED, the blower is weak unless the speed is high, and the page does not state a BS 1363 plug, so check it on arrival. The GST 90 E at £158.50 states 90 mm in wood, 20 mm in aluminium and 10 mm in steel, with a mushroom-handle highlight and 4.7 from 2,427 ratings. The angle cell says 90 degrees, so do not copy the BE’s 45 degree bevel onto the E.

Common questions

Which listing if I already own Bosch 18 V batteries?
The cardboard GST 18V-125 B at £179.98, if you want the deeper class and you will store it yourself. Move to the L-BOXX bow-handle listing at £223.32 when you want that case and a title that says bow handle. Move to the GST 18V-125 S at £207.12 when you want the barrel grip. The GST 18V-95 B at £114.62 is the compact alternative when 95 mm, as Bosch states it, is enough. Every one of them is body only.
Which listing if I only cut sheet and kitchen panels?
The GST 12V-70 carton at £106.99, with a 12 V battery you already own. Reviewers use that class for panels and unit cut-outs, and the title stops at 70 mm in wood. The L-BOXX version at £128.25 adds the case, SDS wording and an LED, and the reviews still mention no blower. If the units are already fitted and the space is tight, that light body is the point of the 12 V saw.
Why not simply buy the 4.8-star saw?
The GST 18V-125 S is the highest star line, at 4.8 from 331, and it is £207.12 without a battery. Reviewers like the barrel grip and mention hardwood. They also describe a bevel shoe with no detents and a switch that can bother a left-handed user. Only three captured reviews are marked United Kingdom. Buy it for that grip and an 18 V pack you own. It is a weak default for every other job.
When is the corded GST 90 BE enough?
When you want a plug, a stated bow handle and a price that includes the power supply. At £129.31 and 4.6 from 320 reviews it covers curves in ply and MDF for the people who wrote about it, with orbital action and a dust set in the box. It is the wrong saving if you need the 90 mm depth printed on the GST 90 E bullets, or if the work is away from a socket and you already own 18 V packs.
Who should skip the £106.99 saw?
Skip the carton GST 12V-70 if the timber is thicker than the stated 70 mm, if you need a dust blower, or if you have no 12 V battery and charger. The sticker is the body in a carton. A slow feed to limit blade wander shows up in the reviews, and one buyer received it without the blade lock. For a 70 mm sheet job you already have the pack for, those faults are the limits, not a reason to ignore the saw.
