A keyhole saw is a unique tool designed to create small holes in materials such as wood or drywall.
What Is a Keyhole Saw
A keyhole saw, also known as a compass saw, features a slim, pointed blade attached to a handle made of wood or plastic. It is ideal for creating holes in softer woods or drywall, such as when installing a new electric switch. Typically, keyhole saws have a single handle that can accommodate various blade types. These blades vary in length (ranging from 5 to 15 inches), width, and the number of teeth, with 8 to 10 teeth per inch being the most common.
How to Safely Use a Keyhole Saw
To safely use a keyhole saw, choose the correct blade and securely attach it to the handle. Depending on the material being cut, you may need to drill a starter hole in the wood or drywall to insert the saw’s tip. For drywall, opt for shorter blades to avoid the tip punching through to the opposite wall. Mark the area to be cut with a pencil.
When cutting, move the saw back and forth gently to follow the marked line. Avoid applying too much pressure, as this could cause the blade to become stuck, making it difficult to continue cutting or remove it. For safety, ensure the keyhole saw blades are sharp and the handle is firmly attached.
How to Maintain a Keyhole Saw
Keyhole saws are generally quite affordable, so having them professionally sharpened could cost more than simply buying a replacement blade or saw.
