A jigsaw blade is a small blade for cutting metal, plastic and many other hard materials. With such tools you won’t have any problems making straight and curved cuts in interior panels, body parts, and other car components.
Types of jigsaw blades
There is a huge variety of these items on the modern market. Classification criteria:
Length. As a rule, this parameter varies between 40 and 250 mm.
Width. Wide blades are more suitable for straight cuts, while narrow tools are better for curved ones.
The type of the shank. Jigsaw blades can have a T-shaped or a U-shaped shank with one or more mounting holes. There are also items that fit the tools made by certain manufacturers only.
Tooth pitch. It can be small (0.8–1.4 mm), medium (1.6–2.8 mm), and large (3.0–4.2 mm). The smaller the pitch is, the cleaner the cut. The tooth pitch can be constant, progressive or intermittent (a succession of teeth with smaller and larger pitch distributed over the length).
The manufacturing material. These tools can be made from durable high-speed tempered steel labelled as HSS, flexible high-carbon tool steel HCS, chrome vanadium steel CV, or durable high-carbon steel HAS. There are also bi-metal tools labelled as BIM.
The products offered in the catalogues of well-known companies differ in the shape and arrangement of teeth as well:
Milled side set teeth. The teeth are pointed alternately sideways. Due to that, the friction is reduced and, as a consequence, the tool heats up less. Such blades ensure a fast cut and can be used for working with plastic and non-ferrous metals.
Milled wavy set teeth. Groups of several teeth are tilted alternately to the left or to the right. These tools are also intended to cut plastic and non-ferrous metals.
Ground side set teeth. Used, as a rule, for wood cutting.
Ground taper & ground teeth. Ensure a straight and thin cutline. Such tools are used for clean cuts in plastic.
Jigsaw blades: usage tips
While working, do not press the tool hard. This might lead to its overheating and breakdown.
Do not use a damaged or dull item: it overloads the motor of the device and might lead to its failure.
Do not use the blades that do not fit. You can get injured or your power tool won’t work properly.
