Tips & Safety

Accessory Bit

There are bits for drilling holes and bits for driving fasteners.

Instructions: Loosen the chuck by hand, insert the drill bit's shank and tighten firmly.

Auger Bit

A bit used to "bore" or create deep holes in wood.

Awl hand tool

An Awl hand tool is a tool with a long metal spike used to mark or to drill holes in different materials.


The flat portion of the saw that sits flat on the work piece.

Instructions: Always make sure the base is resting completely flat while you're cutting. Rocking the base could result in kickback or a misaligned cut.

Bevel Cut

A cut made at an angle towards the inside of the work piece.

Instructions: Secure your work piece and mark your cut. Adjust the bevel to the angle you want. Align the line of cut with the 45° blade guide notch on the base when making 45° bevel cuts. Install the battery or plug the saw in and make your cut on the waste side of your cut mark. It is best to make test cuts no scrap material before cutting your workpiece.


The piece of metal that goes into the drill's tip. There are bits for drilling holes and bits for driving screws.

Black oxide bits

High Speed Steel Drill Bits with a Black Oxide finish which is created by a combination of chemicals and heat during the manufacturing process. Because of this finish, they have a higher resistance of rust and stay sharper longer; for use in general purpose drilling

Brad-point bit

A bit with 3 small points at the tip. Prevents the bit from "walking" when you start drilling. For precise drilling and for wood only.

Bubble Level

The water tube on the top and back of the drill that shows you when you are level with your drilling surface.


The cylinder that opens and closes the jaw of the drill.

Chuck Jaws

The portion at the very tip of the drill that holds the bit in place.

Chuck Key

An additional tool required to loosen and tighten the chuck.


The ring around the front of the drill (usually right behind the chuck) that lets you adjust the torque setting.

Clutch out

When the material you're driving into is too dense or tough for the clutch setting, the drill will stop moving the fastener. This is designed to protect your surface from damage. Adjust the clutch to a higher setting to complete the drive.


A bit that creates a pocket for the screw or fastener to fit in and be flush with the top of the material. The size of the pocket should match the size of the screw head. High Speed Steel countersinks can also be used to clean the edges of holes in metal and plastic.

Cross Cut

A cut made across the grain of the wood or material.

Instructions: Install your battery, or plug in the saw. Secure your work piece and mark your cut. Adjust the blade depth so that the teeth fall just below the work piece (no more than 1/4"). Install your battery, or plug the saw in. Remember to bring the blade just on the waste side of the cut, and make sure the motor side of the saw is over the supported part of workpiece. Make your cut, and be sure the blade comes to a complete stop before lifting the saw back up on any cut.

Cut line indicator

The notches on the front of the base that show you where your blade will go. Some are more accurate than others. Get familiar with your saw and make any necessary marks/adjustments to help you know exactly where your blade will go.

Drill Bits

Used for drilling holes in various materials.

Driving/Screwdriving Bits

Forged or milled metal piece with a tip and a shank used for driving in all types of fasteners

Edge Guide

An accessory that fits through the nose of the saw. It helps make straight cuts.

Instructions: Slide the edge guide through the holes in the front of your saw, and adjust it so that the vertical flat piece rests against the edge of your cutting piece. You can adjust the fence for wide or narrow cuts as necessary.

Factory Edge

When using store-bought wood or materials, the un-cut edges of the material are called factory edges. They are usually already square.

Instructions: Try to make use of factory edges in your projects. Take advantage of the fact that you have two sides that will already be perfectly straight and square.


Hardware that keeps two or more pieces of material together

Flush screw

A screw whose head is exactly level with the material it is fixed to. Might be used for molding or furniture

Fortsner Bit

A wood drilling bit that makes a clean flat bottom hole. These bits shoould only be used on a drill press because of high torque they produce.


The front part of the base.

Instructions: The front will help guide you when you're making plunge or pocket cuts.

Gear Switch

The switch on top that lets you choose between highest speed, and highest torque.

High Speed Drill Bits

General purpose bits used for drilling in wood, plastic, and metal. High Speed refers to the metal used to manufacture these kind of bits.

Keep Side

The side of the wood you are planning to use.


The thickness of the blade

Keyless chuck

The kind of chuck that you can loosen and tighten by hand.


When the saw is forced back suddenly to the user. This can be caused when the blade gets pinched in the wood due to insufficient support, when the blade encounters something inside the wood, the saw blade is misaligned or when the blade depth is set too deep.

Instructions: Kickback can be controlled more easily by taking the following steps: 1: Make sure your work piece is securely clamped. No wiggle. 2: Keep a firm, 2-handed grip on the saw during cutting. 3: Keep a stable, firm stance during cutting. Never put yourself in a postion that makes it easy to lose your balance.

Lag screws

A Lag Screw is a heavy-duty wood screw used for structural support . Might be used for building a deck or trellis.

Lithium-Ion Battery

The most efficient kind of battery for a cordless drill. They typically charge faster, run longer, and don't slowly fade in power.

Ni-Cad (Nickel Cadmium) Battery

The "old school" kind of battery. They tend to take longer to charge, and they gradually lose power as they run down.

Nut driver

A hex design bit used for driving in nuts, bolts and other hex head fasteners.

Pilot hole

Pilot holes are used primarily to prevent the wood from splitting. They can also be used to keep the screws on track and make it easier to drive.

Plunge Cut

A cut that is made inside a workpiece, with no edge to start from. Also known as a pocket cut. May be used for cutting out a hole for a floor vent.

Instructions: Adjust the bevel setting to zero. Using the guard lever, lift the blade guard and start the saw. Rest the front of the base flat against the workpiece with the rear of the handle raised so the blade does not touch the workpiece. Once the saw is up to full speed, slowly lower the blade into the work piece. Release the guard lever once the saw is in the material.

Stripped/ Stripping Screws

A stripped screw has a head in which the tip design has been deformed by a spinning driver bit. They can be very hard to get out.

Sub flush screw

A screw whose head is below the surface of the material it is fixed to.

Tapered head wood-screws

A common type of fastener used for wood work.

Tear out

Tear out occurs when the blade doesn't cut cleanly through the wood. During tear out, the blade makes a rough, splintery exit.

Instructions: Steps to reduce tear out: 1: Make sure the pretty side of the wood is facing down. 2: Make sure the blade you're using is in good condition. 3: Make sure your blade is set for the proper depth for your work piece (never more than 1/4" below) 4: use painter's tape on the top side of the workpiece.

Tile Bits / Glass Cutting Bits

Drill bits with a triangular carbide tip or tips used to drill holes in glass and tile.

Titanium coated drill bits

High Speed Steel Drill Bits with a Titanium Nitride coating which helps the drill bit stay cooler when in use, especially when drilling metal. This helps the drill bit stay sharper longer. For general purpose drilling


A drill's word for power. High torque means the drill/driver is turning the bit very hard.

Waste Side

The part of the wood you're cutting off.

Wormdrive Circular Saw
