HOW TO CHOOSE THE JIGSAW BLADES TO MAKE YOURSELF

Written by Yvan Besnard

What is the main advantage of a jigsaw, it also requires less effort than hand saw is that it has the ability to accept a large number of blades to choose from depending on the work and the material that is to be cut.

These blades do not s'affutent and must be replaced when they become dull or broken.

Each blade has a special material and teeth adapted to the material that is to be cut and the type of cut that you want to achieve, namely faster, sharper or finer.

The blades common:

They can produce all types of cuts in most materials.

But the orientation of their teeth up tends to lift and tear the wood fibers on the face of it when they go back.

The serrated blades reversed

They allow the blades as standard to make all cuts in most materials.

However, their teeth being oriented this time down, they do not cause glare on the face of it.

propERTIES

The cutting blades:

They have a wide and deep indentation to make cuts fast but coarse.

Some are avoyées, meaning that their teeth are inclined alternately right and left.

propERTIEs

The blades grinded:

the back or the back of the blade is ground to be tapered which gives the necessary clearance to avoid being in contact with the edges of the cut and thus limit the effort.

They usually give a very clear cut line, particularly in the fibreboard and particleboard. They can be avoyées or not.

propERTIEs

Wavy blades:

blades for cutting very thin and sharp, with very tight and perforations are generally shallow with a thickness that does not allow a Tooth Setter.

For this type of blades can cut effortlessly, they are to have a wavy kerf wider releasing the blade.

Applications

Steel blades Chrome, Vanadium, HSS allow cuts in chipboard, blockboard or laminated, but also in soft woods, solid wood, plywood, PVC.

Steel blades Carbide and HSS allow cuts in steel, stainless steel, nonferrous metals, mild steel, aluminum, copper, zinc, pvc.

The blades provide enhanced cutting knives cuts in ceramic, slate, tiles, floor tiles.

Applications

The serrated blades reinforced with tungsten carbide allow cuts in the profiles, the fibro-cement, fiberglass, insulation panels and synthetic reinforced.

techniC

The Setting saw: it is the right left angle of the teeth. If the teeth of a saw were straight in the axis of the blade, it would be quickly blocked in its kerf. For that it is wider than the blade, the teeth are inclined alternately right and left sides of the axis: it is the Tooth Setter.

THE PAS: Manufacturers differentiate the blades by the "no" or the number of teeth on a section of 25mm. If a blade has ten teeth on a piece of 25mm, it will also say it has a pitch of 2.5 mm. More space is bigger and allows a cutting blade fast but imprecise. More space is smaller and the cut is clean and precise but it will be time consuming.

TIPS

If you need to cut laminate, it is best to work on the back panel to avoid bursting the decorative face when cutting or using a serrated blade reversed.

the blade tip may differ depending on the machine or the brand used and fastening systems.
