Bosch GST18V-47N 18V Barrel-Grip Jig Saw (bare tool) review

The Bosch GST18V-47N is an 18V barrel-grip cordless jigsaw sold as a bare tool. Bosch lists a dial-controlled 550–2,700 SPM range and four orbital settings. Its exact page names a T-shank blade, insert and non-marring overshoe, but no battery, charger or case. The shared manual says footplate-angle adjustment is for JSH180 only, so beveling is not documented for this GST. This is a source-based assessment, not a test report.

Identify the 47N, not a neighboring 18V model

Bosch identifies retail SKU GST18V-47N and service part 3601EA5110; the manual calls the saw GST18V-47. It appears in current US categories, not proof of production or stock. Keep the suffix intact beside GST18V-50N, GST18V-37N and GST18V-50BN.

The exact package lists one T-shank blade, anti-splinter insert and non-marring overshoe; battery, charger and case are not included. Bosch lists JA1010, JA1011 and JA1013 as compatible, but not as box contents. No vacuum hood or external-extraction setup is documented.

A dial and slide switch replace the trigger

The GST18V-47's dial differs from the JSH180 trigger. Bosch lists 550–2,700 no-load SPM; the manual says speed can be set on or between six numbered marks. A separate slide switch locks on, and Bosch describes an auto-stop when switched off. Buyers who prefer a preset pace may favor this over trigger modulation.

Bosch lists a one-inch stroke and four orbital-action settings. The manual's guidance is material-specific: position 0 for hard materials such as metal or thin sheet, 1 for softer work where cleaner cutting or delicate scrolling matters, 2 for medium-density material such as harder woods or particleboard, and 3 for soft materials such as wood and plastics when faster progress matters more than a clean edge. Bosch says the chart is only a guideline and recommends a scrap cut to choose a setting; that is not an independent performance claim.

Do not mistake a blower for extraction

The manual calls the chip blower “always on” while the saw is running, and Bosch says it helps keep the cut line visible. It is not a dust collector. The exact page lists compatibility with a guide, steel overshoe and insert, but not a GST18V-47N vacuum hood or nozzle. If source capture is a requirement, ask Bosch to confirm the exact adapter and hose arrangement rather than assuming a generic accessory fits. The manual also advises coolant or lubricant alongside the cut line for metal work and says not to force the saw through material.

The current technical table and the manual agree on a one-inch stroke, 4-23/32-inch wood capacity, 5/16-inch steel capacity, and the manual's 13/16-inch aluminum maximum. Bosch's product highlights complicate that reading: one statement gives 4-1/2 inches in wood and 7/8 inch in aluminum, while another says 4.7 inches in wood and 0.8 inch in aluminum. These are manufacturer specifications, not measured cut results, and the wood/aluminum claims are not fully consistent within the page. If a particular thickness is near a stated limit, confirm it against the individual tool and current manual before selection.

The bevel distinction is model-specific

Unlike the JSH180, the GST18V-47N page does not list a bevel range. More decisively, the shared manual labels its footplate-angle adjustment section “Model JSH180 only.” Accordingly, the GST18V-47N is not a match for a buyer who needs a documented angled shoe; it is not safe to transfer the top-handle model's 45-degree capability just because both are explained in one booklet.

The images and manual also make the control change visible: GST18V-47 has a barrel grip, speed dial and slide switch; JSH180 has a top handle, variable-speed trigger and switch lock. The 47N's no-mar overshoe is specifically listed in its package, while JSH180's page lists a bevel wrench and its manual says that tool has an adjustable shoe. Both share the nominal one-inch stroke, orbital guidance, T-shank format, blower and light, but their grip, controls, package list and bevel status remain distinct buying facts.

What to verify before choosing it

Choose this model if barrel-grip handling, a speed dial and lock-on switch fit your work, and a fixed-angle shoe is acceptable. Bosch identifies 18V / AMPShare compatibility, but the manual directs users to the battery/charger list supplied with the tool. Neither item is included; verify the approved pack rather than relying on voltage alone.

Confirm the GST18V-47N suffix, package items, and lack of documented vacuum or bevel. Choose a T-shank blade for the material and use the orbital chart as guidance, not a finish guarantee. If capacity is decisive, resolve Bosch's conflicting wood/aluminum figures. Marketing language does not establish accuracy, runtime or durability.

Sources and limits

This assessment uses Bosch's exact product page, linked manual and US 18V category. An exact-name CPSC query returned an empty array on 2026-10-28, not future or alternate-name recall clearance. No price, stock, rating, test or ownership claim is made.
