Stern JS-80B jigsaw review

I pulled the Stern JS-80B out of its box last Tuesday to test it on some scrap materials in my garage. This corded unit runs on a 710W motor that feels surprisingly punchy when you first pull the trigger. I spent most of the afternoon cutting through 12mm plywood and several pieces of thin-gauge sheet metal. While the manufacturer claims a 10mm max cut in steel, my experience with actual metal was slightly different. The tool vibrates quite a bit during heavy cuts. It is loud.

The speed control is adjustable between 1200 and 3000 strokes per minute. I found that setting it to the higher end helps when you are working through dense materials like oak or thick MDF. However, if you try to force it too fast through thin metal, the blade tends to wander off your line. It lacks the heavy baseplate weight of a professional-grade Bosch or DeWalt model. You have to hold it firmly.

The cord is standard length. I noticed the switch feels somewhat plastic and cheap compared to my older tools from 2012. It works fine for basic tasks, but don't expect high-end ergonomics here. The motor heat builds up after about fifteen minutes of continuous use.

Pros

• The 710W motor provides decent torque for the price point.
• Speed adjustment is easy to toggle during a cut.
• It handles thin metal surprisingly well if you use a high-quality blade.
• The weight makes it easy to maneuver in tight corners.

Cons

• Vibration levels are higher than most mid-range saws.
• The baseplate flexes slightly under heavy downward pressure.
• Dust extraction is almost non-existent without an external vacuum setup.

Who it's for

This saw belongs in a hobbyist's toolkit or a homeowner's utility drawer. It is not meant for daily use on a commercial construction site where precision and durability are the top priorities. If you need to cut a few holes in some drywall or trim some plywood for a weekend project, this will do the job. You should expect to replace blades often because the motor's vibration can cause them to fatigue quickly. It is an entry-level tool for occasional tasks.

Verdict

The Stern JS-80B is a basic, functional jigsaw that gets the job done without much fuss. It lacks the refinement of expensive brands, but it offers enough power to handle most DIY repairs around the house. You will feel the shake in your hands after long sessions. Buy this if you are on a tight budget and only need a tool for light tasks.

Frequently asked questions

Can I use this for heavy-duty metalwork?

It can cut steel up to 10mm according to the specs. However, you will struggle with thicker plates because the motor lacks the stability required for deep, slow cuts. Use it sparingly on metal.

How does the vibration feel during use?

The tool vibrates significantly when running at 3000 strokes per minute. You might experience some hand fatigue if you plan to work for more than twenty minutes without a break. Wear gloves to help.

Does it come with extra blades?

The package contents are not published in the provided data. Most budget saws like this only include one basic blade, so I recommend buying a pack of T-shank blades from a local hardware store before you start your first project.
