A circular saw is a power tool that consists of a circular blade with sharp teeth that can cut various materials such as wood, plastic, and metal. These saws are typically powered by electricity or battery-powered.

Circular Saw: A Brief History

Circular saws were invented in the late 18th century and were used as rip-saws for turning logs into lumber. By the mid-19th century, the equipment had become common in sawmills in the United States. However, archeologists have unearthed evidence proving the tool’s usage from as early as the bronze age (particularly the Indus Valley civilization).

Types of Circular Saws

  • Standard: Also known as sidewinder saws, these are the most common types. Basically, the motor of a standard circular saw is positioned parallel to the blade, making it compact and lightweight. They are great for general tasks and are suitable for both enthusiasts and professionals.
  • Worm Drive: The motor of a worm drive is oriented perpendicular to the blade and connected by a worm gear. This design provides more torque and is useful for heavy-duty applications and other demanding cutting tasks.
  • Compact: This woodworking power tool is smaller and lighter their standard counterparts. This makes the tool useful in tight spaces.
  • Trim Saw: Trim saws are great for precision cutting and finish work. This includes trimming moldings, making accurate cuts, and cutting smaller pieces of material. 
  • Miter Saw: A miter saw’s blade is mounted on a pivoting arm that allows precise angle adjustments. Perfect for making angled cuts.
  • Track Saw: Also known as the plunge cut saw, this tool can cut materials along a straight guide rail or track, allowing accurate and splinter-free cuts.
  • Cordless: These saws run on rechargeable batteries, eliminating the need for a power outlet.

Circular Saw Handling Safety

Power tools can be hazardous especially for woodworking beginners. It is important to understand how these equipment work to prevent any form of accidents and injuries. Here are some tips for safe circular saw handling:

  • Proper Training: Proper training is essential for woodworkers who wish to advance beyond hand tools.
  • Choose the Right Tool: Use only the right power tool for the job.
  • Wear Safety Gear: Protect your eyes from flying debris and your ears from the machine’s loud noise. Wear a dust mask as well to avoid inhaling dust particles.
  • Inspect the Tool: Check the saw regularly for any damage that could cause accidents. Make sure the blades are always sharp.
  • Secure the Material: Always make sure that the material is secure before making the cut to prevent kickbacks from the equipment.
  • Be Aware of Kickbacks: A kickback is a sudden and powerful movement by the tool towards the user. Keep the blade guard in place to minimize risks.
  • Keep Hands Clear: Keep fingers and limbs away from this wood-cutting power tool at all times.
