Masonry reciprocating saw blade

How to change a masonry reciprocating saw blade

Over time, all the cutting blades wear out and become blunt. Occasionally, the user may damage the blade and will have to change the blade of a masonry reciprocating saw. Changing the cutting blade of a reciprocating saw is quite easy. But first, you must choose the correct blade.

You may use the reciprocating saw to cut wood, metal, fiberglass, brick, drywall and much more. The type of blade you insert will affect the ease with which you make each cut, as well as the quality.

First of all, you should buy a blade that is compatible with the size of your saw, as well as your model. Make your decision based on the material you will cut with the reciprocating saw.

  • For pure wood or plastic, a flexible cutting blade of high carbon steel will suffice.
  • For wood with nails, a bimetal blade is better. The bimetal blade has a flexible body of steel and carbon and high speed steel teeth. It is more expensive than a carbon steel blade, but can last up to 10 times longer. In addition, it is resistant to heat and to break.
  • To make a clean cut in green wood, choose a specialized blade with “teeth” that cut when the sabre saw blade pushes and pulls.
  • The metal is cut better with diamond blades.
  • To cut brick, clay tiles or pipes and terracotta, try a blade with tungsten carbide powder. The blades with tungsten carbide powder also work well for cutting fiberglass, ceramic tiles and cement panels.

Masonry reciprocating saw blade teeth

  • How far apart are the teeth of the sabre saw blade will determine the type of material that the blade can cut.
  • The fewer teeth per inch, the faster you can cut and the coarser edges will remain on the wood.
  • Blades with a large number of teeth per inch are better for cutting metal.

A tip: Three teeth should come in contact with the material, any material, at all times to avoid getting hooked.

Masonry reciprocating saw blade depth and width

For some works, the best cut will be obtained with a long or wide blade. The masonry reciprocating saw blades measure between three and 12 inches long.

  •         Long blades make cuts that are deeper than short.
  •         The short blades with tapered backs are perfect for immersion cuts.
  •         Broad blades are less likely to wobble and bend than narrow ones.
  •         The thick blades are more stable while they are used than the thin ones.

6 easy steps to change the blade of a masonry reciprocating saw

Once you have the right blade, it is easy to change the blade of a masonry reciprocating saw and replace it with the new one.

  1. Put on the protective accessories. To avoid accidents, protect yourself with gloves and goggles or safety glasses before removing or replacing the sabre saw blade.
  2. Unplug the saw or, if it is a wireless model, remove the batteries. These safety precautions will prevent you from accidentally turning on the reciprocating saw while changing the blade.
  3. Point the blade to the opposite side of your body. Rest the saw against you to support its weight, but the cutting blade should be as far from your body as possible.
  4. Locate the locking collar. It is a ring at the base of the blade that holds the blade in place.
  5. Pull the locking collar inward, toward your body, and slowly turn it counterclockwise. This will loosen and force the spring into the saw to release the used cutting blade with a click.
  6. Slide the new blade into place, right where the old one was. It does not matter if the “teeth” of the saw are looking up or down. But, this time, turn the locking collar clockwise. This will pull the blade in and secure it in place with a fork. Keep turning until the blade clicks.
