Jigsaw Review – What Is The Best Jig Saw ?
This is part three of our " How to choose the best jigsaw " review series, examining key parts and important features any professional jigsaw should have. Part 2 can be found here: Bosch Jigsaw Review >>
Two Kinds of Electronics
Electronics have long ago made their way into the universe of power tools, and the jigsaw is one of them. Take a closer look. There are two types of electronic controllers found on jigsaws. There are:
- Variable Speed Electronic
- Constant Speed Electronic
Present day variable speed electronics will allow you to adjust the speed of the jigsaw on the fly. Of course, what you do depends upon the material being cut. Woodworkers benefit from variable speed controllers, when cutting thin plywood, metals, or an array of plastics where you want to reduce the cutting speed. Most jigsaw manufacturers such as Bosch, Makita, Dewalt, Festool, Ryobi, Black and Decker, Hitachi or Craftsman offer some or all of their models with variable speed electronic.
Keeping a constant speed control is best accomplished by a small electronic devise built into the unit. It doesn’t require a visible switch and it automatically boosts the motor power as it senses the cutting encountering difficulty. This way the jigsaw maintains the blade speed providing consistent performance. It is very important in heavy-duty jigsaw applications, such as for carpentry or framework, where large depths of cut are common.
Ergonomics and Visibility Improvement on the Best Jigsaws
When you read the review of a jigsaw brand, or when you compare and consider buying one, you might want to have a closer look at some of the improved "features" of various jigsaws, and other power tool companies. Not all features are essential for a top of the line saw, but you might want to be aware of them. These may be:
- Extra Light on Cutting Line
- Laser Line
|Soft Grip||Extra Light on Cutting Line|
|Various manufacturers set soft grip inserts into the handle part of the jigsaw. The rubbered material lets you handle the tool without slippage providing much better control.||A little light spot on the cutting line on this Metabo jigsaw.|
Additional Important Parts for Increased Jigsaw Durability
Durability and reliability are key features for any jigsaw. In addition, other common attributes for professional tools are in the motor power. Still other components will enable you to make an informed decision when it comes to buying a really durable and reliable jigsaw. Here is a quick lineup of those attributes that makes a professional jigsaw durable and reliable:
Best Choice - Jigsaw Metal Gear Case
This is the front part of any jigsaw housing. It holds the barrel and the gears. The best professional jigsaws are made of a metal (cast) gear case. The majority of DIY units (non-professional) encase their barrel and gears in a plastic housing. For the professional tool, a metal case (holding the gears and bearings) guarantees a much longer life for the power tool. The metal case also guarantees a lasting resistance against overheating during heavy usage. Important tip for reviewing some of the best jigsaws gear cases: As you look for any metal gear case on a jigsaw, make sure you watch the tools front end in detail, as some manufacturers (e.g. Festool), cover their metal gear case with PVC for heat and design purposes.

Full Single Part Housing vs. Two Part Jigsaw Housing
Price is your first indicator between a professional and the DIY power tool. The second attribute involves the type of housing used. Professional units have what is called "full housing." That means the housing or body and armature is held in a single body together with all gears and bearings. This means all motor components offers the user a higher precision. In comparison generally speaking DIY jigsaws are less durable as the tool body is in two halves held together by a series of screws.
