How do I know that. Well… I've had to build both.

This example can be used in various situations. For example: Garage cabinets as compared to your beautiful kitchen cabinets or furniture going into your Penthouse as opposed to things you would build for a kid's tree house. It's all about your desired quality and perception. And, what you consider acceptable.

Sometimes the cuts made by a circular saw are OK. Other times a cabinet grade table saws are the Best Power Tools for the job. It also depends on the type of material you will use. Oak or Plywood?

Let's start with my picks. Then we will see where that takes us as I go somewhat crazy with ideas and memories of my building career.

1. The Best Power Tools To Have: Circular Saw. Probably the most basic and versatile handheld power tool, in the hands of an experienced user, the circular saw can substitute for many other tools. While it takes some practice for most beginners to get comfortable with a circular saw, it quickly becomes a standby tool to handle a lot of cutting tasks very quickly. This should be the first of the power woodworking tools every beginning woodworker should consider.

2. Power Drill: While cordless drills are very popular and convenient and versatile, corded drills have the power to handle a number of drilling tasks. Additionally, corded drills are variable speed, which allows the user to drill anywhere from a very slow RPM all the way up to the drill's top speed. A 3/8-inch corded version for the beginner's first drill would suffice. No Need to go out and pay top dollar for this great tool. There are many good choices for under $40.
3. Random Orbital Sander: The third Best Power Tools every beginner should buy is a random orbital sander. While palm sanders are less expensive and can use plain sandpaper, the random orbital version doesn't sand in patterns, but in a random motion. This will reduce any sanding marks that may appear on the stock. Sanding disks are readily available in a number of grits to fit your machine.
4. Router:  While many routers available today offer two different bases (a stationary base and a plunge router base), for most beginners, a quality stationary base model will take care of quite a number of tasks, and can be mounted in a router table should you choose to invest in one down the line. Choose a model that is at least 1 1/2-HP. No need to get any stronger until you get the hang of this powerful and extremely versatile Power Tool. What makes this one of the best power tools, is the variety of bits you can own and there vast abilities.  
5: Compound Mitre Saw. I chose another blade tool as one of the best power tools because any woodworking enthusiast must have one. A compound sliding miter saw is invaluable for cutting compound angles on the ends of stock. Once you get good on a miter saw, you'll find that your circular saw spends a little more time in the drawer than it used to. This magnificent and versatile saw replaces the old radial arm saw.

We can add to this list very easily as different jobs start to emerge. A contractor should have all the tools needed to do any job a homeowner might need accomplished. The Best Power Tools anyone can really have are all the ones you can afford. Let's go shopping for the Best Power Tools available.

1. Safety glasses: These prevent dust, debris, wood shavings, shards from fiberglass, etc from getting into the eyes. Safety glasses are one of the most basic pieces of safety equipment that must be used when working with the best power tools.

2. Protection for the ears: Power tools can generate a lot of noise, which may sound louder in the cloistered environment of a workshop; in order to minimize damage to the ears, it is advisable to wear earplugs.

3. Having the Best Power Tools for the job: It is important to know the right tools for the job in order to avoid injury to oneself and damage to the materials. To this end, it is advisable to thoroughly read the instruction manuals provided with the equipment and get familiar with the recommended safety precautions.

4. Correct method of using tools:Corded Power Tools should not be carried by their cords; tools that are not in use should be disconnected; and while handling a tool connected to a power source, fingers should be kept away from the on/off switch.

5. The right clothes: Long hair should be tied and loose clothing should be avoided. Ideally, clothing that covers the entire body should be worn and heavy gloves should be used in order to avoid sharp implements and splinters from hurting the hands. Masks prevent inhalation of harmful minute particles of the material that is being worked upon. Steel-toed work boots and hard hats can also be worn.

6. Tool inspection: The Best Power Tools should not be employed in wet environments and should never be dipped in water; they should be checked periodically for exposed wiring, damaged plugs, and loose plug pins. Nicked cords can be taped but if a cut appears to be deep, a cord should be replaced. Tools that are damaged or those that sound and feel different when used should be checked and repaired.

7. Cleanliness in the work area: This should be maintained because accumulated dust particles in the air can ignite with a spark. Of course, flammable liquids should be kept covered and away from the place where power tools are being used. An uncluttered work area also makes it easy to maneuver the power tool; often distractions caused by a tangled cord can result in an accident.

8. Care with particular tools: Compound Sliding Miter Saws and table saws should be used with a quick-release clamp and a wood push-through, respectively. Extra care should be taken while using nail guns and power belt sanders.

9. Keep tools in place: Power tools should be returned to their cabinets after use to prevent them from being used by an unauthorized and incapable person.

10. Lighting: It is important to use proper lighting while working with the best power tools, particularly when working in the basement and garage where lighting may not be satisfactory.
