Dado Blade in Detail

A dado blade is a blade used to cut a;

- Dado joint –a slot joint cut into the surface of a wooden material and perpendicular to the grain of the wood.

- Groove – this is similar to a dado joint only that a slot is cut parallel to, with or against the grain of the wood

- Tenons – a tenon is a projecting piece of wood cut out for the purpose of inserting it into a mortise on another piece of wood.

- Rabbet- this is a two-sided joint/groove cut out usually at the end or along the edge of a wooden piece

- Finger – a finger joint is a cut made on the brink of a wooden material with the intention of joining it together with another piece. The cut is made on two separate wood pieces which are then glued together.

These are not any regular cuts you are used tomaking. They are rather more precise cuts, especially in width and depth. They are mostly preferred when one needs to add a visually aesthetic appeal to construction.

While many types of blades can be used with saws to make cuts in work pieces, a dado bladeis most preferred for the above-mentioned type of cuts. Other types of saw blades used for DIY projects include;

- Ripping blade – this kind of blade has very few teeth and a large gullet for removing waste pieces. It is used majorly for cutting wood along the grain.

- Crosscutting Blade – this blade features more teeth than the rip blade and has a smaller gullet. It is used to cut wood with the grain for a smoother finish.

- Combination blade- this one consists of a series of about four to five teeth characterized by a large gullet. It is used mainly to cut both with and against the grain and is also used for making miter cuts.

- Plywood blade –as the name suggest this blade is used for cutting plywood and has very many teeth since plywood is thin and needs extra smooth cuts.

- Diamond blade – this is a very sturdy blade that is designed for hard materials like ceramic, tile concrete and glass.

- Abrasive blade – like the diamond blade, this blade is also relatively sturdy and is use for cutting tiles, masonry and sometimes steel.

When you go to buy a blade for your saw or cutting tool, ensure that you choose the right one for the saw and for the type of material that you will be cutting.

How To Maintain Your Saw Blade in Top Shape For Best Quality Cuts

There is a magnitude of things you can do to keep your blade in good condition. Maintenance is not just for making the saw look good, but it helps to increase the longevity of the blade as well as enhance its performance. Here are tips on how to maintain your saw blade.

· Use the right blade at all times

Different types of materials and cuts require different types of blades. Therefore, ensure that every time you embark on cutting projects that you are using the right blade for the particular material.

For example, dado cuts require the use of a dado blade to get the best cuts. In the same regard, you will use a blade with more teeth to make a dado cut in a thin material while a fewer toothed dado blade to cut a thick material.

· Use a proper setting

Before you start cutting, ensure that all the saw settings are tuned correctly. The fence and slots need to be aligned parallel to the blade.

Also, ensure that you maintain the right blade projection (the distance from the top of the material to the upper part of the blade when cutting). Maintaining a proper blade projection will help you to get the best finish, one that is clean and smooth.

· Maintain a proper blade sharpening

To be able to cut accurately and quickly, you will obviously need a sharp blade. A blade with the right form of sharpness will give you not only accurate cuts but also clean and smooth cuts with fewer rough finishes.

When you feel that the blade is blunt, you should make a point of sharpening them. And when doing so, always ensure that that the shop correctly matches the Pre-Score of the blade. Remember not to test cut with the blade in between sharpening as this may affect the blade’s sharpness.

Also, avoid sharpening the blade now and then as it may also reduce the longevity of the blade itself.

· The blade should always be clean

Dado blades and any other saw blades work best when clean. If you leave dirt, dust and any form of debris to build up on the blade, then you subject the blade to more friction. Constant friction causes pitch buildup due to a lot of heat production.

A dirty blade will obviously give you a hard time cutting, will give you poor cuts and as a result of putting too much pressure during cuts you will end up shortening the life span of the blade as well as compromising its efficacy.

Cleaning a saw blade is not difficult, you just need a cleaning product, spray bottle if the cleaner doesn’t have one, oil and a cloth. The best way to clean is to use a spray bottle with the cleaner.

To clean; after you are done the cutting, remove any small pieces of the material from the blade and spray the cleaner on it. After that, rinse off the cleaner and wipe the blade clean. Oil it well and then store it in a safe place away from the reach of children.

Remember to turn off the machine and unplug it from the power source before cleaning it to avoid accidents. If your machine has a lock the better; just lock the switch so that you don’t accidentally turn it on when during cleaning or storage.

Importantly, choose your cleaning products wisely. The wrong cleaner choice may end up damaging the blade, and you don’t want this to happen. There is a variety of product in the market. Just search for the best one on the web or visit your local store for the best blade cleaner for your dado set.

When choosing a cleaning product, avoid anything flammable. Also, do not just settle on any cleaner but rather buy a specified tool cleaning product as these have very minimal safety risks.

· Observe safety precautions

It is true that power and hand tools tend to cause accidents which can turn out to be fatal when not used correctly and carefully. If it’s your first time to use a saw or any power tool, ensure that you maintain safety precautions at all times. Most power tools have these precautions indicated in the user’s manuals or label. Check them out and observe them to the latter.

A good example of these safety procedures is to;

  • Use the right settings
  • Wear protective gear like safety goggles, apron and closed shoes
  • Keep the machine away from children when not in use
  • Always switch the machine off and unplug it when you stop using it
  • Work in an open space
  • Use the right blade for the right material and cut
