What size blade do you use on an 8 1/2 sliding miter saw?

For an 8 ½-inch saw, choose a blade with a diameter of  8¼” – 8½”. You cannot use a larger size blade on this size saw or any other saw as well, use the size that is compatible with this one. This diameter blade can offer you different cutting capacities according to the various bevel and miter angles you’d set.

8 ½-inch saw with the same size blade has a maximum cutting capacity of up to 8 ½-inch at 45 degrees and 12 inches at 90 degrees. The general maximum cutting capacity at 0 degrees’ miter and bevel angle is 2-3/4 inch x 10 5/8 inch. And at 45-degree miter and bevel (left) it is around 1-1/2-inch x 7-1/2 inch.

The Ultimate Buyer’s Guide of 8 1/2 Inch Miter Saw

Shopping for a miter saw can be frustrating and you wouldn’t want to spend hours browsing through the internet to find the best one. So, after thorough research, we have gathered some points for you to ponder before buying one:

  • Power and Capacity

A sliding compound miter saw can easily cut angular, miter, and bevel cuts and are made to cut wood but are also able to cut non-ferocious metal and PVC. This clearly explains that they have a huge power capacity to go through various materials. The power of the motor is very important as it ranges from 9-ampere to 16-amperes, the higher the motor power, the better is the performance.

Though these ones are small in size and are lightweight as compared to their counterparts, they offer professional-level cutting efficiency. They are an ideal choice for trimming and moldings as they have a full crosscut capacity on a 2×12 inch board and 2×8 inches at 45 degrees. Use a finer blade, and see how perfect the cuts would get.

  • Compactness and Portability

The main benefit of buying an 8 ½ inch saw is its compactness, obviously dragging the heavy saw all day long from one job site to another could be really tiresome, it could even affect your health, moving an 8 ½ inch saw with an easy to grip handle is a practical choice as carrying it around to install baseboards and flooring and even building decks becomes stress-free.

  • Ease to operate

Whether you are a professional or a beginner, a miter saw with its sturdy built looks like a daring tool, but it doesn’t mean that it has to be difficult to operate as well. So choose the out-of-the-box accurate one with easy to access controls and easy to read and adjust miter and bevel readings. Always choose a flexible saw offering power, performance, and durability which functions like a performer.

  • Blade Size

The blade size chosen must be compatible with the miter saw otherwise it would affect not only the material but also your safety. Larger blades can smoothly make long, deep cuts as compared to the smaller ones which are perfect for meticulous cuts at smaller jobs. For example, an 8 1/2 inch blade should be fitted into an 8 1/2 inch saw, as saws are generally designed to accept only their exact size of the blade.

Smaller blades have thin kerf, which cannot make deep cuts. You can put a small blade on a large saw, but you cannot put a larger blade on a smaller saw. E-g a powerful 12-inch blade on the 12-inch miter saw has the capacity to cut deeper, wider boards smoothly as compared to smaller blades.

  • Laser guide

The laser guide is an important feature but it totally depends on the person using the miter saw. If you are a professional, then you can smoothly create accurate cuts without the laser marker but if you are a hobbyist or a beginner then this feature could be really helpful for you as it would help you align your blade with the cut-in line on the material.

Some tools are equipped with LED lights along with a laser guide for precision but some are not, in some you’d find a laser guide useful in others it’s inoperable. So the level of usefulness depends on what type of woodworker you are.

  • Dust collection

It is one very essential feature to keep your health as well as the work environment clean. Most miter saws fail to provide an effective dust chute. Other ones include dust collection adapters or ports for vacuum hose as well sawdust hoods are available for maximum collection of sawdust or debris, so whichever option you opt, make sure that they provide optimum level efficiency. A number of dust collection hoods work well with both sliding miter saws and sliding compound miter saws.

With a vast variety of hood options available in the market, you can install door trims, oak flooring, window trims, and crown moldings without worrying about the clouds of dust flooding your saw and your workstation.

  • Safety

Buy the one with a clear blade guard to have the perfect view of the cutting line, the guard protects the saw portion above the table. The blade guard will completely cover the blade when you’ll raise the saw providing protection from the blade. Safety clamps will help secure the material, prevent it from warping and the spindle locks on the saw will lock the head while replacing the blade. The electric brake system installed on some saws, the minute you press the trigger make the saw stop spinning its blade within seconds. These are some useful safety features to bring into consideration before you decide on buying a miter saw.

  • Single or dual bevels

A single bevel sliding compound miter saw can do all the cuts that a dual bevel will do, it’d just require a lot of time and effort because in a double bevel you can easily cut both sides of the material without having to rotate the board. But obviously, they are more expensive than the other, so if you are a DIY’er then choose a single one as they are easy to move otherwise go with a dual bevel miter saw.

  • Weight

10 and 12-inch sliding miter saws with extra rails and broad bases are heavier and hence require more space in the workstation which is a hassle, whereas 7 ¼ and 8 ½ are compact and easily fit anywhere on the workshop. So make your purchase keeping in consideration the size and weight along with the level of transportability you expect from the chop saws.

  • Wood Size

Sliding compound miter saws are specifically designed to cut deeply through wide thick boards of wood that are greater than 8-inches and are up to 12-inches wide without the hassle of having to relocate the boards.


Wrapping Up

Thoroughly review the article before making the final choice of which brand to go with. All four of them are great compact tools, crafted by some recognized manufacturers, and then choose the one that perfectly fits your price range and matches your sawing needs. Though the saw size and blade are small, the sliding compound feature gives you most of the capabilities of a larger miter saw along with a strong power motor without the hassle of weight and movability.

None of the above industrialists have compromised on the performance and durability of the saw. It is always recommended to buy a good quality miter saw that can provide you accurate cuts as you wouldn’t want to waste your materials, time, and effort on something useless.

Happy Compact Saw Shopping!
