Intro
A circular saw cuts straight lines beautifully, but the moment you need to follow a curve, cut out a sink hole in a worktop, or scribe a piece of skirting board to fit an uneven wall, it becomes the wrong tool for the job. A jigsaw is the answer to every cutting task that is not a straight line. Its narrow, vertically reciprocating blade can follow tight curves, start from a plunge cut in the middle of a panel, and reach into corners that no circular saw blade could ever touch. For decades, the jigsaw was a corded tool that was light enough to use one-handed but always came with the familiar cable-tangling frustration. Cordless jigsaws have now matured to the point where an 18-volt brushless model delivers the same cutting performance as a corded equivalent, with the freedom to take the tool up a ladder, into a loft, or around a kitchen without a trailing lead. For kitchen fitters cutting worktop apertures, carpenters scribing trim to uneven walls, and DIYers tackling laminate flooring around door frames, a good cordless jigsaw is one of the most versatile tools you can own.
Generalities
When choosing a jigsaw, the blade change mechanism is the feature you will interact with most often — and a tool-free SDS-style system that lets you eject and insert blades with a single lever is a world apart from older designs that required an Allen key. Motor type matters: a brushless motor extracts more runtime from each battery charge and eliminates the brush wear that eventually kills brushed motors. Stroke length — how far the blade travels up and down — determines cutting speed and capacity, and a 25-millimetre stroke is typical for a capable mid-range machine. Orbital action settings let you adjust how aggressively the blade moves forward into the cut on the upstroke; more orbital action means faster cutting in soft materials like pine, while zero orbital action gives a cleaner finish in plywood and laminates that are prone to tear-out. A variable-speed trigger gives you control for starting cuts slowly in delicate materials. Dust extraction, even if it is just a blower to clear the cut line, makes a big difference to visibility. A splinter guard — a small plastic insert that sits flush against the blade — is a simple but effective way to minimise tear-out on the top surface of the cut.
This review looks at a cordless 18-volt jigsaw from a leading professional power tool brand. We will cover the specifications, the blade system, the ergonomics, and how it performs on curved cuts, straight cuts, and the kind of scribing and fitting work that demands a jigsaw in the first place.
Description
The jigsaw runs on Bosch Professional's 18-volt battery platform and features a brushless motor for efficient power delivery and extended tool life. It accepts standard T-shank jigsaw blades up to 125 millimetres in length — the most common format — covering everything from fine-tooth blades for clean plywood cuts to aggressive coarse-tooth blades for fast ripping in softwood and even metal-cutting blades for sheet steel and aluminium. The stroke delivers efficient material removal with each reciprocating cycle, and the orbital action can be adjusted in steps from zero — for clean, splinter-free cuts — up to maximum for fast, rough cutting where finish quality is not critical. The variable-speed trigger lets you start cuts gently and ramp up to full speed as the blade bites.
The standout ergonomic feature is the SDS blade change system. A lever on the side of the blade housing ejects the old blade and locks the new one in place with a single motion — no tools, no screws, no fiddling with a hot blade. This matters because jigsaw work often involves switching between blade types as you move from rough cutting to fine finishing, and anything that makes blade changes faster keeps your workflow uninterrupted. The saw body is compact and weighs just 1.9 kilograms without a battery, making it light enough for one-handed operation when cutting curves in sheet material or trimming worktops overhead.
The base plate tilts to 45 degrees for bevel cuts, and the saw includes a splinter guard that fits into the base plate directly in front of the blade, pressing down on the wood surface to prevent the top veneer from lifting and tearing as the blade teeth exit the cut. A dust extraction port connects to a vacuum cleaner or dust extractor, and the kit includes an extraction adapter. There is also a built-in air blower that can be directed at the cut line when you are not using extraction. An LED work light illuminates the cutting area for improved visibility. The soft-grip handle and low-vibration design make extended use comfortable — noticeable when you are spending an hour scribing skirting boards or cutting multiple worktop apertures.
The jigsaw comes as a kit in a Bosch L-BOXX 136 system case — a stackable, clip-together storage solution that integrates with other L-BOXX and Sortimo cases. Inside the box you get the bare tool, one T 144 D wood-cutting blade, the dust extraction kit and adapter, and the splinter guard. The L-BOXX is genuinely useful for professional users who transport tools between sites and want a system that keeps everything organised and protected. As with all Bosch Professional 18-volt bare tools, no battery or charger is included, so this makes the most sense for users already invested in the Bosch blue battery ecosystem.
The jigsaw holds a 4.7 out of 5 star rating from 260 customer reviews on Amazon and ranks at number 59 in the jigsaw category. The feedback volume is smaller than some older models but the rating consistency is strong. Bosch Professional backs the tool with their standard warranty, and spare parts are available through their authorised service network. At around 150 euros for the bare tool with the L-BOXX case and accessories, the price is competitive for a brushless cordless jigsaw from a premium professional brand — comparable to equivalent models from Makita, DeWalt, and Milwaukee. For a kitchen fitter, carpenter, or serious renovator who already owns Bosch 18-volt batteries, this is a straightforward and sensible addition to the tool kit.
Pros and cons
Pros
- SDS tool-free blade change — eject and insert blades in a single motion without tools, making blade swaps between rough and fine cutting almost effortless.
- Brushless motor provides longer runtime per charge, cooler operation, and a longer service life than a brushed equivalent.
- Weighs only 1.9 kilograms as a bare tool — light enough for comfortable one-handed use during overhead cuts and long scribing sessions.
- Includes a splinter guard and dust extraction kit — the splinter guard minimises tear-out on the top surface, and the extraction port keeps the cut line visible.
- Adjustable orbital action lets you choose between fast, aggressive cutting and clean, splinter-free finishing — one tool adapts to both rough and fine work.
- Ships in a genuine Bosch L-BOXX 136 system case that stacks with other L-BOXX units — practical for professional transport and organised van storage.
- 4.7 out of 5 star rating from 260 reviews — consistent user satisfaction and the backing of Bosch Professional's service network.
Cons
- Bare tool only — no battery or charger included — the total cost rises significantly if you are not already invested in the Bosch Professional 18-volt platform.
- Only one blade is included in the box — you will need to purchase a blade assortment for different materials and cut qualities before tackling varied projects.
- 125-millimetre blade length limits maximum cutting depth in thick timber — not suitable for sectioning beams or cutting materials over approximately 60 millimetres thick.
- No variable-speed dial on the body — speed is controlled entirely through the trigger, which gives less precise speed locking than a separate dial for long straight cuts.
- At 150 euros as a bare tool, the price puts it in the professional bracket — occasional DIY users may find a corded jigsaw at half the price more appropriate.
Use cases
A brushless cordless jigsaw for professional carpenters, kitchen fitters, and serious renovators already on the Bosch 18-volt platform — ideal for curved cuts, worktop apertures, scribing, and any cut that is not a straight line.
Kitchen Worktop and Appliance Apertures
Cutting the hole for a sink or hob in a laminate worktop demands a jigsaw — no other handheld tool can start a plunge cut in the middle of a panel and follow a rectangular outline with tight-radius corners. The splinter guard and zero-orbital setting produce clean edges that need minimal clean-up.
Scribing Skirting, Architrave, and Trim
No wall is perfectly straight, and no floor is perfectly level. Scribing skirting board or architrave to follow the contours of an uneven wall or floor is the jigsaw's signature skill. The light weight and one-handed operation make long scribing runs comfortable.
Curved and Decorative Cutting
Cutting arches, circles, waves, and decorative shapes in plywood or MDF for furniture making, set building, or craft projects. The narrow blade follows tight curves that a circular saw could never attempt, and the variable-speed trigger gives control for intricate work.
Laminate and Wood Flooring Around Door Frames
Laying laminate or engineered wood flooring inevitably involves cutting boards to fit around door architraves, pipe penetrations, and irregular room shapes. The jigsaw handles these cuts on the spot — measure, mark, cut, and fit without walking back to a mitre saw.
Expanding a Bosch Professional 18V Kit
For a tradesperson already running Bosch blue 18-volt batteries, adding the bare jigsaw fills a capability gap at a reasonable cost. Drop in an existing battery and you instantly gain the ability to make curved and plunge cuts that a circular saw or recip saw cannot handle.
