Safety Measures To Be Taken While Using Circular Saw

best circular sawA circular saw is one of the most versatile and useful tools in the shop. With a few tips, making a wide variety of cuts with a circular saw is both enjoyable and safe. Follow these suggestions, and you’ll soon be able to make anything from a few custom-fitted shelves and building an entire house faster and with better quality. The first thing to do before cutting is to set the saw at the proper blade depth. If the blade is set too deep, more of the blade is exposed, increasing the danger. Also, with a deep blade setting, the saw has more possibility of binding and kicking back. In addition to being safe, the circular saw cuts more efficiently with the proper blade depth setting. The best circular saw which has the easiest way to set your blade depth settings is the  DEWALT DCS391B Circular Saw in my opinion.

Circular Saw Blade Depth

To determine the correct blade depth, unplug the saw and place it alongside the material that you are cutting. Retract the blade guard. Loosen the knob or lever that adjusts the depth and move the saw’s base until the blade extends from ¼ inch to ½ inch below the material. Tighten the adjusting knob or lever and you’re all set to go. Using a circular saw means that you have to be careful and thoughtful about what you are cutting and how you are using the saw. circular saw blade depthA serious danger is binding. This happens when the piece that you are cutting bends in towards the blade and causes the material to bind, causing a dangerous kickback. You should always make sure that the piece you are cutting is positioned so that the cut off material is free to fall easily away from you.

Tip: When you plan on buying your first circular saw make sure to read a few circular saw reviews written by experienced users on ecommerce sites such as Amazon as these reviews are unbiased and will help you make an informed decision. If you end up going for the wrong circular saw you can always return it and opt for another saw of your liking.

Another potential for binding is when you are crosscutting plywood. The plywood has to be supported across the entire length. Failure to support the whole way creates the possibility of binding, splintering or tearing as the cut-off piece drops off. If you’re using sawhorses, use a couple of 2x4s to cover the span. When you have to rip a long piece of lumber, it’s probably going to be better to do this on a table saw. But, if one’s not handy, then you go to the trusty circular saw when the cut doesn’t have to be totally accurate. The trick is how to keep the board in place while you are making the cut. If the piece isn’t very wide, clamps are awkward to use; they get in the way. One way is to tack the lumber down to your sawhorses; let the nails protrude so they can be easily removed.

If you’re ripping a more expensive piece of wood, use finish nails to the material in place, and pull them from the backside after making the cut.The most versatile circular saw is the 7 1/4 inch such as the Makita XSS02Z 18V circular saw . There are a lot of models available from the simplest like Ryobi to the more expensive such as from Milwaukee with lots of additional features. The 7 1/4 inch usually has enough power for most projects. The better models are able to cut bevels, for example.

Benefits and Uses of Circular Saw

A circular saw is a hand-held electric saw that uses a flat circular blade to cut wood, metal, or plastic. Different circular blades are used depending on which material needs to be cut. It is designed for ripping and crosscutting materials that might be too large for a table saw. A circular saw is used for straight-line cutting only. The handle of the saw has an on/off switch and an arbor nut to hold the blade in place. This saw also has guards to protect the user from touching the blade while in use. These types of saws also have height/depth and bevel adjustments.

Why they are worth having

This is an extremely important tool to have if you’re working with large amounts of wood, metal of plastic that a simple table saw could not be used for. The circular saw is normally used for heavy work where stronger and thicker materials are being used. It is important, when using a Circular saw, to first inspect the wood (or other material being used) and remove all nails and screws before cutting. Serious accidents may occur if the rotating blade of a circular saw hits a steel screw or nail.

What you can use them for

The circular saw, as mentioned above, can be used for projects that require ripping and cross cutting, bevel cutting and plunge cuts. When ripping (or cutting), the material should be supported on a large table or on the floor, and several pieces of scrap wood should be placed underneath the wood for additional support. This scrap material should be at least 1″ thick in order to ensure that the saw’s blade does not cut through the surface below. For more narrow cuts/rips, first consult the rip guide that usually comes with your circular saw. If this guide is not included, it can be purchased separately. For wider cuts (such as plywood) clamp down a long metal rule or a straight piece of wood as a guide. It’s important that before you begin cutting, you adjust the saw’s depth of cut so the blade doesn’t cut through to the scrap wood or floor that you are using as support. Also ensure that the power cord is free and clear of the cut area so that doesn’t cause issues.

Bevel cuts (cuts that are not at right angles) are performed in the same way as crosscuts and rips. Again, make sure that the blade does not come into contact with the underlying supports or the scrap wood. Plunge cuts are when you begin the cut in the middle of the work, rather than at the edge. One example of a plunge cut is when you need to put a skylight into the middle a roof, rather than starting at the edge. First, mark the areas that you want to cut out, and then begin near the corner of one side and place the front edge of the saw base firmly on the wood. Lift up the saw guard using the correct procedure, and make sure that you have adjusted the depth of cut to a suitable depth. Make sure you consult the user’s manual so you are well aware of how to best use the circular saw.

The Need For Regular and Proper Maintenance of Circular Saw

A worm-drive circular saw is one of the more common power tools among both professional tool-users and weekend do-it-your-selfers. They are universally useful and have the tenacity to make most any construction or demolition project spectacularly simpler. Few users, though, understand the importance of regular maintenance, like lubrication.

Fortune, however, was kind to worm-drive circular saw users, and lubing your circ saw is a pretty simple process. A quick word of advice, though, before beginning this brief tutorial: always check your oil levels before using the saw. The oil level should never fall below the lowest threads in the tool housing, and, should that oil become thick or excessively dirty, flush the saw of the old oil and entirely relubricate it (*see below for flushing instructions).


The first and foremost step in getting that saw good and lubed is disengaging the tool, ensuring it has no power source to draw from, and resting it firmly (on its foot) on a sturdy, flat surface. Next, you simply need to reach and check the oil. To do this, use the tool’s wrench (the same one used to remove the saw blade) to remove the oil plug (this is the metal nut just above oil the reservoir that reads “oil level in operating position” on the right hand side of the tool). Add fresh oil to the oil reservoir allowing it to fill enough to spill out (a little) of the oil-hole at the arrow pointing up from the reservoir.

Next, you simply need to replace the oil plug and all will be right as rain with your worm-drive circular saw. Oh, and although you absolutely must use high-quality, high-speed oil (never, ever use motor oil), it is highly and always recommended that you use only Bosch or Skil lubricating oil in these tools. Using these lubes also offers the extra piece of mind in knowing that your tool is smooth and happy, and the simplicity of knowing exactly what to buy (Bosch lubricant: part number WD7LUB, Skil Lubricant: part number 80111). So, when lubing these Bosch and Skil saws, use only Bosch or Skil oils.


Now, if when checking the oil, the existing oil in the saw is ultra-dirty or thick, you will need to entirely flush the bad oil from the saw. To do this, immediately replace the oil plug, reengage the tool and allow it to simply run for about one minute to warm and loosen-up the existing oil. Remove the oil plug once more and invert the saw allowing the oil to drain completely from the reservoir.

Next, fill the reservoir with kerosene, return the plug again to its plugged position, reengage the tool and allow it to run for one minute. This will flush and clear-out the gear housing and reservoir of any residue. Remove the plug and invert the tool once more to entirely drain it of the kerosene. After ensuring you’ve drained as much kerosene as possible from the reservoir, refill it with the aforementioned Bosch or Skil worm-drive circular saw lubricant (fill it, again, to a bit of a spilling point at the oil-hole). Return the plug, and you have successfully lubed your circular saw and single-handedly enhanced its life and performance. Good job.
