When using a combi drill or other type, the four main bits you’ll come across or need for your walls are a masonry bit, a wood bit, a tile bit, and a twist bit. Drill bits from different brands will look slightly different but they will still feature the same main characteristics to help you distinguish between them.
What is the smallest spade bit? Spade bits are usually available in metric sizes ranging from 6mm to 36mm and imperial sizes ranging from 1/4″ to 1 1/2″. The size of the bit is usually engraved onto the body of the spade itself so that each bit can be easily identified.
What are short drill bits called?
The shortest standard length drill bits are screw-machine-length. They are named for their use in screw machines. Since that doesn’t accurately describe the product in layman terms, we refer to them as short stubby length drill bits.
What sizes do spade drill bits come in? Spade drill bits are available in a wide range of sizes from 6 mm right up to 38 mm diameter.
What’s the difference between a Forstner bit and a spade bit? Spade bits are the smallest of the three hole cutting tools; they generally come in a range of ⅜ an inch and 1 ½ inches. Forstners are a bit larger; their range is from ¼ an inch to 2 ¼ inches. The cutting diameter of a carbide burr ranges from 3/32” to 1” and only up to about 1” in cutting depth.
Is a paddle bit the same as a spade bit? A spade bit, also known as a paddle bit, is a wood-boring drill bit (that is flat) with two sharp lips, two spurs, and a center point. The Irwins Tool Firm first designed the paddle bit in 1968, and its simple design makes it easy to remove waste material from boreholes.
What are four types of drill bits? – Related Questions
Which is better spade bit or hole saw?
Spade drill bits are faster than hole saws. If you want to drill multiple holes in less time, choose a spade drill bit. On the other hand, If you want to drill perfect clean and smooth holes, choose a hole saw. They are well known in woodworking industries as the hole saw bit for wood for making precise holes.

Do drill bits come in different lengths?
They come in a wide range of sizes, finishes and materials such as High Speed Steel, Cobalt and Solid Carbide. Jobber length drill bits’ flute length and overall length are dependant on the diamater of the drill bit.
What do Forstner bits do?
A: Forstner bits are mostly used in the woodworking industry to drill holes that are larger than those that can be made with ordinary drill bits. While other drill bits, such as spade bits, can perform a similar function, Forstner bits are significantly more precise and produce a clean cut with a flat bottom.
How do you drill a hole in a 4 inch piece of wood?
What is a brad point drill bit?
Brad point drill bits are specially designed to drill and bore clean holes in hard and soft woods without wandering. These drill bits have been designed with a center pin as seen in the images below and on the right. A Brad Point Drill Provides a clean, straight, and accurately sized hole in wood.
What bit makes the cleanest hole in wood?
Forstner Bits These are great for drilling through-holes and flat-bottomed holes for hardware installation where your cutting depth needs to be precise. Forstner bits are typically used for 1/2″ to 2″ holes and will deliver the cleanest cut possible.
Why do spade bits have a hole?
The hole on a spade bit is used to pull electrical cables back through boreholes once they have been drilled. At a push, they can also be used to hang the spade bit on a wall-mounted rack.
Can I use a Forstner bit with a hand drill?
But Forstner bits can also be tricky to use in a portable (handheld) drill, as they’re better suited for use in a drill press. When used in a portable drill, a Forstner bit has a tendency to “walk” or drift away from the center, especially at the beginning of the operation.
Why does my spade bit keep getting stuck?
Spade/paddle bit best practices Once you have contact, more pressure may be needed to drive the bit through the material. If the bit gets stuck and doesn’t seem to be making progress, try clearing away wood shavings from the bottom of the bit and then trying again.
Do you need a pilot hole for spade bit?
Drilling a Hole with a Spade Bit Before you drill: If you’re trying to drill a very precise hole (say, for furniture or other wood working), you should drill a pilot hole first. The pilot hole will serve as the guide for the spade’s center point and will eliminate inaccuracies in your placement.
How do you cut a hole in wood that doesn’t go all the way through?
I usually just wrap a piece of masking tape around the drill bit leaving the correct length exposed. You can either wrap enough layers of tape around so that it is fairly thick, or leave a “flag” of tape sticking out. Either way will let you drill to the proper depth without the risk of marking the surface.
Why is it called a Forstner bit?
Named after the inventor, Benjamin Forstner.
Are Forstner bits worth it?
Unlike the standard twist bit, Forstner bits are optimized for woodworking applications and cut exceptionally precise, clean-edged holes in wood. Because they’re designed to produce a minimum amount of tear-out when exiting the material, Forstner bits are the best bit for drilling through holes.
Are spade bits accurate?
Spade bits are popular for rough carpentry and electrical projects because they enable users to bore holes quickly and accurately in wood, plywood, and other softer materials.
What are the Gold drill bits for?
Titanium Drill Bits – Best for Metals They’re easily recognisable as they have a gold-coloured coating. The titanium makes the bit much harder and is slightly self-lubricating, which makes it perfect for drilling hard metals.
What is the strongest drill bit?
Diamond Drill Bit Polycrystalline diamond (PCD) is one of the hardest drill bit material, which can be used on the toughest materials, such as glass and ceramic.
What do the Colours of drill bits mean?
From experience, white is generally a fully ground HSS drill and should be of the best quality. The gold ones are titanium nitride plated and are generally either the best or poorer at fooling around.
What does HSS mean on a drill bit?
(75 products) HSS drill bits, an acronym for high speed steel drill bits are extremely hardwearing and particularly well designed for drilling into metal surfaces, as they are much more resistant to the heat generated from the fast speed operation.
How do I know which drill bit to use?
The diameter of the hole you drill should be slightly smaller than the diameter of the screw. So, for example, if you’re using a 3.5 mm screw, use a drill bit with a diameter of 3 mm. If you’re using wall anchors as well as screws, the drill bit and anchors should have the same diameter.
How do you cut a drill bit shorter?
1)Drill a hole using the bit you plan to use 1″ (or so) down into a piece of scrap. 2)Using a hacksaw, carefully saw a kerf down to your drilled hole. 3)Insert the bit into the hole and lining it up with the saw kerf you just made where you want the cut.
Why is it called a jobber drill?
These drills, were of medium length and suitable for a wide variety of jobs, coining the term “jobber-length”, reflecting the same concept of terms like “general purpose” and “multipurpose”. Today, jobber drill refers to the length of the drill itself.
What are mechanic length drill bits?
A mechanics length drill bit is a bit that has a shorter overall length, as well as a shorter flute length. This allows them to be used in tight spaces. The shorter length also allows them to be more resistant to breakage, making them ideal for drilling into harder materials and hard metal drilling.
How do you control the depth of a spade bit?
Spade bits can be used both in a drill press or a hand-held drill, and there are two ways to regulate hole depth when you’re drilling by hand. If you only need to ballpark hole depth, then wrap a piece of electrical or masking tape around the shank.
