A jigsaw tool is a power tool used for making curved and intricate cuts, including stenciled designs. Basically, it is driven by an electric motor and has a blade that can cut materials such as wood and metal, among others.

Jigsaws: A Brief history

The first variants of the jigsaw can be traced back to the 19th century. However, modern jigsaws were introduced in 1947 by Scintilla AG (later acquired by power tool brand Bosch). 

The jigsaw’s design was developed from Scintilla AG engineer Albert Kauffman’s idea, which he presented by replacing a sewing machine’s needle with a saw blade.

Parts of a Jigsaw Tool

Here’s a breakdown of the parts of a jigsaw and how they work:

• Electric Motor: This power tool has an electric motor that provides power to drive the blade.
• Blade Mechanism: The power tool’s blade is attachable to a reciprocating mechanism. This converts the motor’s rotary motion into an up-and-down movement.
• Blade Attachment: The blade fits into a blade holder at the bottom of the equipment. The tool also usually has a quick-release mechanism that allows users to easily change blades.
• Orbital Action: Many jigsaws feature an orbital action setting that enhances cutting efficiency and helps clear away debris from the cutting area.
• Base Plate or Shoe: The jigsaw tool rests on a flat base plate, also known as the shoe. This helps secure the blade in position and provide stability.
• Trigger and Speed Control: Jigsaws typically have a trigger that starts the motor. Users can also increase the blade’s speed by pressing further on the trigger to provide more power.
• Cutting Guide: Jigsaws usually come with a cutting guide or laser guide that helps you follow a predetermined cutting path.

Types of Jigsaws

The jigsaw tool is useful in various trades and applications such as woodworking, construction, crafting, and DIY projects, among others. Here are different types of jigsaws:

• Corded Jigsaw: Traditional jigsaws that use a power cord and outlet to operate.
• Cordless Jigsaw: Jigsaws that run on rechargeable batteries for added portability.
• Barrel Grip Jigsaw: This type has its handle on top of the saw’s motor housing, allowing for better control when doing intricate cuts.
• D-Handle Jigsaw: This jigsaw’s D-shaped handle allows the user to grip it from behind. Perfect for tasks that require more aggressive cutting.
• Orbital Action Jigsaw: This one employs “orbital action” or “pendulum action, by combining forward and backward motion with the up and down movement.
• Bevel-Cut Jigsaw: These are useful for making bevel cuts and creating angled edges and joints.
• Compact Saw: Smaller and lighter saws that are useful for tight spaces and light-duty tasks.

Jigsaw Tool Handling Safety

Jigsaws can be hazardous, especially for woodworking newbies. Understanding how power tools work is crucial in preventing any form of accidents and injuries. Here are some tips for handling jigsaws safely:

• Proper Training: Proper training is essential for woodworkers before advancing to power tools.
• Choose the Right Saw: Use only the right saw for the task.
• Wear Safety Gear: Protect your eyes, ears, and lungs.
• Inspect the Tool: Check the power tool for any damage and wear.
• Secure the Material: Keep the material secure before starting the cutting process.
• Keep Hands Clear: Keep fingers and limbs away from the blade at all times.
