Greenlee Drill and Tap Bits
The greenlee drill bits are manufactured from stainless steel. They come in various sizes and shapes. These drill bits have been used for years to make drilling jobs easier. Greenlees are widely available online and at hardware stores like Lowes or Home Depot.
You can buy them at your local hardware store too if they stock them.
How do I choose the right size?
You need to decide which type of bit will fit best into your drill press. There are different types of bits depending on how deep you want to go with your drills. For example, a 7/16″ bit will work fine for most small holes. A 5/64″ bit will work better for larger holes.
When choosing the correct drill bit, it’s important to consider the diameter of your drill press. If you’re using a drill press with a 9/32″ hole, then you’ll probably want to use a smaller bit than if you were using a 7/16″ drill press.
What size bits should I get? What size bits do I need?
Size is usually measured in 32nds of an inch. A 1/4″ bit is the same as a 25/32″. A 13/64″ bit is 3/4 of an inch. There are certain types of bits that can only go deeper by two or three increments at most. For example, you can’t get a 22.5/64″ bit because that size doesn’t exist.
Should I get a t-shaped bit or a straight bit?
The t-shaped bits are used for smaller holes. The straight bits are longer and used for larger holes. Usually, you can use either a t-bit or a straight bit for each job but it’s helpful to have both.
Is the size written on top of the drill bit?
It should be on top of all of the bits that you buy. If you can’t find the size, then measure it with a ruler.
What if I want to make super big holes?
You have three options for making really big holes. The first option is to use a special attachment on your drill press. The second option is to use a Forstner bit. A Forstner bit is designed to cut out a circle. It’s shaped like a pumpkin and cuts out the middle of whatever you’re drilling. The third option is to use a hole saw with an arbor. The hole saw spins the same way that regular drill bits do but it has teeth that break the wood instead of drilling through it. You can also use a hole saw to make holes in thicker pieces of wood.
Should I get a ratcheting mechanism for my drill press?
A ratcheting mechanism makes it easier to drill straight holes. It is helpful if your drill press does not have a lot of power or if you are drilling really deep holes. If you are using a hand drill, then a ratchet isn’t as necessary. You can still use one, but it’s more useful for a drill press.
What type of bit should I use with my drill press?
There are two types of bits to choose from. There are twist bits and there are hammer bits. The twist bits have sharp edges that cut into the wood when you spin them. The hammer bits have flat surfaces with indentations. You use a hammer to tap the bits into the wood.
What is a brad point bit? What is an auger bit?
A brad point bit looks like an upside-down mushroom. It’s designed to drill super-straight holes without going off track. An auger bit is a long, spiral-shaped bit. It’s used for drilling really big holes.
What is difference between a spade bit and a paddle bit? Which one do I need?
A spade bit has a flat tip. It’s good for making holes in two different types of wood at the same time. A paddle bit looks like the letter “T”. It’s good for making holes in thicker pieces of wood.
What is a Forstner bit?
It’s a special type of drill bit that makes holes without splintering the wood around the hole. It looks like a pumpkin and cuts out the middle of whatever you’re drilling.
What is a bradawl?
It’s a tool that is used to poke small holes in order to create space for nails or screws.
What is a mortise?
It’s a block of wood that has been hollowed out to accommodate a tenon.
What is a tenon?
It’s a long, rectangular piece that is hollowed out on each side. It can be used in picture frames, doors and windows.
How do I drill holes?
Always clamp the wood that you’re working on so that it doesn’t move while you’re drilling. It’s best to drill from the bottom side of your wood so you don’t splinter the top of your wood. It’s helpful to draw an ‘X’ where you want to make your hole. It helps you stay centered and keeps the drill bit from wandering. Start with a small bit and then work your way up to the size that you need.
Which drill bit do I use for what material?
Use a Forstner bit for drilling into plywood, hardwoods and composites. Use spade bits for drilling into softwoods. Use auger bits for drilling really big holes in really thick materials. Use brad-point bits for doweling. Use masonry bits for drilling into concrete or brick.
Using a Jig
What is a jig?
It’s a specialty tool that helps you make cabinets, bookshelves, tables or anything else with straight sides and stable legs. It also helps you make joints such as “half-laps” or “dovetails.” Jigs are very helpful but they usually cost a lot of money. You can sometimes make your own jigs, but they take a lot of time to design and build.
What is the difference between a jig and a template?
A jig has guides and stops to keep you from building something wrong. For example, a jig can have a piece that slides into a channel to keep a board from entering the router bit at an angle. A jig doesn’t give you exact measurements like a template does. A template just gives you a shape to follow.
How do I use a stair gauge?
Start by determining the size of the stairs you need to make. Measure the rise (distance from the bottom of one step to the bottom of the next) and the run (the distance between the feet of the beginning and end of a set of stairs). Mark these measurements on a 1″x2″ and cut it to fit between the risers and treads. Use this as a gauge to lay out the positions of the individual boards that will make up your stairs.
How do I use a sliding bevel?
The sliding bevel is used to mark the angles for cutting a series of identical parts. First, line up the arrow on the blade with the zero mark on the scale. Then, line up one side of your part against the stationary peg. The back edge of your part should rest against the sliding bevel. Adjust the blade so that its cutting edge exactly lines up with the top edge of your part. Make a line where the cutting edge crosses the top edge. Now flip the part over and repeat the process on the other side.
How do I use a framing square?
To lay out a right angle, place the short leg of the square against the line and push it until the long leg extends out at a right angle. Check your line for accuracy. To check if a board is square, place the square’s long leg against one edge and then push it until the short leg rests against the other edge.
How do I use a compass saw?
The compass saw consists of a blade, a handle and a flexible cable that connects the two. You hold the handle and push or pull the cable to make the blade spin around like a normal saw. To cut with a compass saw, push the cable forward to make the saw teeth bite into the wood and pull it back to saw backwards. Push and pull in a steady motion to cut completely through the wood.
What is a hand saw?
Hand saws have teeth set into the edge of the blade. They cut when you apply pressure pushing the teeth against the wood. You can get saws with anywhere from 24 to 40 teeth per inch. The more teeth, the smoother the finish but they require more effort to use.
What is a rip saw?
Rip saws have fewer teeth that are wider and stronger for cutting with the grain of the wood. They have fewer teeth because they do not need as many teeth to cut across the grain like a crosscut saw does.
What is a crosscut saw?
Crosscut saws have more teeth per inch and smaller teeth than rip saws so they can cut both with and across the grain of a board. They are designed to cut faster than rip saws because they can cut both with and across the grain of a board.
What is a keyhole saw?
The narrow blade and small teeth of this saw are designed to remove wood in cramped places difficult to reach with any other type of saw. The bow handle makes it easier to control the saw. You can get keyhole saws with straight or curved blades.
What is a coping saw?
The thin blade and sharp teeth of the coping saw are ideal for cutting intricate shapes in wood. The adjustable bar that holds the blade lets you change the angle of cut, so you can create joints and other details.
What is a birdcage saw?
The birdcage saw works like a full size saw but with much smaller teeth and a shorter blade. They are used to cut dovetails and other fine joinery work. The smaller blade also lets you cut in tight places where a full size saw won’t fit.
What is a hack saw?
These inexpensive saws are designed to cut metal. You can find hacksaws with fine or coarse teeth. The finer the teeth, the smoother the finish but they require more effort to use.
How do I use a handsaw?
There are two basic kinds of handsaws: crosscut and rip. Crosscut saws are used to cut across the wood grain. Rip saws are used to cut with the grain.
How do I use a rip saw?
Rip saws have fewer teeth than crosscut saws so they can cut with the grain of a board. They are designed to cut faster than crosscut saws because they can cut with the grain.
How do I use a crosscut saw?
Crosscut saws are used to cut across the grain of a board. They have more teeth than rip saws so they can manage to cut across the grain.
Hold the saw with three fingers below the handle, your thumb behind the handle and your last finger and your pinky together above the handle. This gives you control over the saw while keeping your fingers away from the cutting edge.
