A jigsaw is a kind of saw that employs a reciprocating blade to cut irregular curves in wood, metal, stenciled artwork, tiles, etc. Jigsaws were invented in the nineteenth century and used a treadle to control the blade. Scintilla AG (acquired by Bosch later) created the contemporary portable jigsaw in 1947.
The jig is only one aspect of the equipment. You must select high-quality jigsaw blades that fulfil your needs. Due to the wide variety of jigsaw blades available from reputable manufacturers, you may have difficulty picking the right jigsaw blade. When deciding which jigsaw blade to use, think about the material and the cutting you’ll be doing.
Jigsaw Blades Types
Jigsaw cutting blades come in various shapes and sizes to suit multiple uses. The type of blade you use will also affect the machine’s speed and material finishing. Here we have classified Jigsaw blades into several types according to the type of shank, the number of teeth, the material composition, and the suitability for cutting various materials. Multi-purpose blades may be more cost-effective and convenient, but some blades are better suited to cutting specific materials.
Here go some of the most common types of jigsaw blade:
T-shank jigsaw blades
Jigsaw blades with T-shanks are the most common and are compatible with most modern jigsaws. These blades are popular due to their ease of installation and general use. They have a tang on the top of the shank that fits into the jigsaw blade clamp.
Universal jigsaw blades
Universal jigsaw blades, also known as U-shank jigsaw blades, are distinguished by a U-shaped cut at the shank’s head. Because many modern jigsaws include a tool-free blade changing system for T-shank blades, they are becoming less common.
Types of Blade Materials
The material of the jigsaw blade directly impacts its durability and usefulness for various applications. To guarantee that you utilize the best jigsaw blades for your application, you must first identify the most appropriate material.
The following are the most frequent types of materials:
High carbon steel
Jigsaw blades made of high carbon steel are the most cost-effective and versatile. They’re used to chop wood in a variety of ways.
Jigsaw blades made of high-speed steel have a lot of toughness and heat resistance. This jigsaw blade is compatible with cutting metal, plastic, and wood, among other materials.
Bimetal jigsaw blades are incredibly durable. A combination of steel is applied to produce this blade. They are typically heavy-duty metal-cutting jigsaw blades. You can also use this blade with wood.
Jigsaw blades made of tungsten carbide are the gold standard in heat resistance and endurance. It is also known as tile cutting blades. These blades can slice solid materials such as ceramics and stainless steel.
Jigsaw Blades: How Long Do They Last?
The predicted lifespan of a jigsaw blade depends on several factors like the usage of different power levels and cutting applications. When used repeatedly, all jigsaw blades will wear down and lose their cutting effectiveness. If there is apparent cutting resistance, you should sharpen any blades before fitting and avoid attempting to force the jig. New and worn blades will have a noticeable change in sharpness.
Jigsaw Blade Replacement
A spring-loaded lock is attached at the top of the jigsaw. This lock aims to keep the jigsaw blade safe during the cutting operation. The spring-loaded lock will be positioned parallel to the blade guide as the initial stage in the blade attachment process. The blade should then be cautiously inserted, and the lock should be released. You can test the blade’s security by gently tugging on it.
Before removing the jigsaw blade, make sure it’s completely cool. It’ll also be necessary to remove the jigsaw’s battery. Then the user needs to push up the spring-loaded lock to release the blade.
What Jigsaw Do I Require?
When selecting a jigsaw, consider several aspects like frequency of use, the benefits of corded vs. cordless models, the blade’s appropriateness, etc. To pick the best jigsaw for you, consider several factors, like the type of material you will cut and other essential features. It’s also possible that you have a preference for a particular brand.
Other important considerations depend on whether you are seeking the best cordless jigsaw or the best jigsaw for cutting metal:
Length of Jigsaw Stroke
The stroke length refers to how much ground the blade covers in a vertical direction during the cutting process. The greater its cutting efficiency is, the longer its stroke length will be. Cutting a wide range of materials is also possible with tools with the most extensive stroke lengths.
The amount of electricity required will depend on the cutting purposes and estimated frequency of use. For most cutting operations, a jigsaw with a motor output of over 500w will be enough. If you want to cut hard materials frequently, you’ll want to get a jigsaw with more than 700w of power. A cordless jigsaw’s power is measured in Volts.
The cutting speed will influence the materials that you want to slice:
Slow: For cutting ceramics, wall tiles, and glass, jigsaws with a slow cutting speed of 500 to 1,000 strokes per minute are ideal.
Medium: The jig can cut plastics and non-ferrous materials at a mid-range cutting speed of 1,500 to 2,000 strokes per minute.
Fast: Jigsaws with a rapidly-cut speed setting of more than 2,000 strokes per minute is designed to cut wood.
