1) Know Your Projects
If you’re a DIYer considering your first miter saw it’s vital that you have outlined your projects for yourself, and understand the duration of each project. If you’re making picture frames for your 2 grand kids you might as well just use a manual miter saw and not even fool with a cheap power miter saw. If you’re doing all the molding in your 3,000 square foot house then an investment in a miter saw might be justified… especially if you’ll be doing siding later on, or other projects that require highly accurate angles. Know your projects – know the stock you’ll be using.

2) 8 Inch Miter Saws 10 Inch Miter Saws vs. 12 Inch Miter Saws
Once you’ve decided that you’re going to get a miter saw for sure you have to make a decision about whether you’re getting an 8 inch or a 12 inch. Don’t let this turn into a “bigger is better” issue for yourself. Buying too much saw is a waste of your cash resources and wasting resources is wrong. Appropriate reasons for getting a larger saw include longer cuts on larger stock. If you’re working with really large stock then you might consider a sliding compound miter saw, but we’ll get to that. As a rough rule of thumb though, the 10 inch will cut molding that’s around 5 inches wide and the 12 inch will cut molding that’s 6 inches wide. Fudging – though dangerous – can potentially win you some inches.

3) Miter Saws vs. Compound Miter Saws
The “compound” in the compound miter saw allows you to put tilt into your cuts. This tilt saves you a step if you have complex angles, also called bevels, in your projects. Ideally your blade will tilt to both the left and the right.

4) Compound Miter Saw vs. Sliding Compound Miter Saw
The sliding feature allows your blade to pull or push through longer cuts, and it turns the standard compound miter saw into something of a radial arm saw. It’s an expensive add on, but if you’re a contractor you’ve probably already got a “SCMS.” If you’re a hard-core extreme DIYer then a sliding compound miter saw could be the right choice for you too. The cost should have you thinking twice even if its application to your projects doesn’t.

5) Digging Into Other Miter Saw Features and Accessories
Easy to Read Indexes: it’s nice if you don’t have to get out a magnifying glass every time you have to adjust your saw angle. You’ll be faster and more accurate if your gauge indexes are easy to read while cutting.

Positive Stops: common angles should have easy to fit detents… but it’s equally important that these detents be easy to override should you need to cut a 44 degree angle some time.

Electric Brakes: a blade that slowly coasts to a stop puts you in more danger and means you have to wait longer between cuts. An electric brake puts you in more control of your work.

Dust Bags: save your lungs and collect that dust! Consider a dust bag if your miter saw doesn’t connect to your shop vacuum.

Laser Guide System: an adjustable laser guide can speed up your work and give you more confidence in your cuts. Sometimes the laser guides that come standard on miter saws aren’t adjustable – you’re better off without this type.

Convenient Self-Retracting Blade Guards: it’s wise to closely investigate your blade guard. It should be convenient and conducive to work – this will make you less likely to remove it which is very dangerous.

Sliding Fences: sliding fences give you support for taller stock on your miter cuts.

Portable Stands: if you’re going to be working outside your wood shop or in a mobile fashion then a portable stand can be a good safe way to get accurate cuts outside.

Is bigger Mitre saw better than smaller one?

If you're using a mitre saw with a larger blade that's around 305mm (12 inches) or more in size, you'll find that this can be used for making deeper and wider cuts. Smaller saws that are 254mm (10 inches) or smaller are easier to handle and are better used for smaller, more detailed cutting work.

Is a 10

A 10-inch miter saw gives you plenty of wriggle room because most cuts are no more than four inches long. A 10-inch saw is preferable because this machine is smaller and lighter than a larger version. Plus, smaller blades are also less expensive.

Can a 10in miter saw cut a 2x4?

Types of Miter Saws The bigger the blade, the deeper and wider its maximum cut. Typically, a 10-inch miter saw will cut a 2 x 6 at 90 degrees and a 2 x 4 at 45 degrees; a 12-inch miter saw will cut a 2 x 8 at 90 degrees and a 2 x 6 at 45 degrees.

Can you cut 4x4 with 10

The 10-inch miter saw is a common power tool used for cutting different sizes of wood. This includes the 4×4 as the cutting depth of a 10” saw is roughly 5 ½”. This means that you can make the cut in one pass.
