Buying Guide For Best Drill Bits
Types of Drill Bits
Brad-Point Drill Bit
Brad-point drill bit is best for drilling woods. It comes with a sharp spur at the top of the tip and spiral grooves or flutes on the sides. The sharp tip positions the bit in the proper spot and the flutes grabs wood chips. Thus it expels wood chips from the hole when you are drilling, producing a clean hole. Brad-point bits deliver fast jobs that require a high degree of detail. Here is a list of best brad point drill bits.
Twist drill bit:
This is a standard bit that comes with a pointed cutting tip. Like the brad-point bit, the Twist bit has fluted sides that remove waste as you drill. The twist bit is ideal for home use and you can use it on wood, thin metal, and plastic.
Countersink drill bit
The countersink bit is ideal for creating a pilot hole with a wider opening at the top for countersinking screw heads. Countersink bits are mostly used in wood. This type of drill bit allows you to insert the fastener long enough so the head doesn’t stand out above the surface of the material.
Forstner drill bit
19th-century inventor Benjamin Forstner invented this drill bit and this bit is ideal for use on wood. Foster drill bit also features tip spur just as the brad-point bit to achieve precise drilling. But the body of the bit is is different and designed to drill a flat-bottomed hole. We use Forstner bits to create holes to hold dowels. Professionals use the Forstner drill bit in high-end furniture and cabinetry construction.
Spade Drill Bit
Spade drill bit is also known as paddle bit. A spade bit has a tip spur for precision. The flat blade can cut up to 1.5 inches across large holes. Spade bits are typically used to drill holes through wood studs to pass wires and water supply lines.
Hole Saw Drill Bit
Hole saw drill bit can make large holes in wood, thin plastic, ceramic tile, and other sheet goods. The hole saw bits typically come in two pieces: the bit and a cylinder with sharp, saw-like teeth. The bit has a shaft that attaches the bit and puts it into the drilling machine.
Step Drill Bit
The shape of the step drill bit is like pyramides. This bit is used to enlarge existing holes. Typically professionals use this bit with thin materials but sometimes they also use it on sheet plastic as well. Usually, The manufacturer labels each “step” on the bit with the corresponding size hole it drills.
Material
Steel
These are the least expensive drill bits. Steel drill bits are suitable for softwood and other soft materials only.
High-Speed Steel
These drill bits are harder than regular steel. High-speed steel bits can tackle harder wood, as well as aluminium, PVC, and fibreglass.
Titanium-Coated
These drill bits are pricier than the other two types of drill bits. Titanium-coated bits don’t create many frictions like steel which reduces the heat produced while you work. These bits will effectively put holes through most woods, fibreglass, soft metals, and PVC, or similar plastics.
Carbide-Tipped
Expensive but very durable and remains sharp long time even after maximum use. Steel, high-steel, or even titanium-coated bits can not beat this drill bit in terms of durability. Carbide-tipped bits are widely used to drill through tile, masonry, or concrete.
Black Oxide Coated
These are regular steel bits with black oxide coating to ward off rust and corrosion. Black oxide provides an extra layer of durability for regular steel bits.
Cobalt
Cobalt is the most expensive option when you are buying drill bits. Cobalt drill bits are super strong. Professionals use cobalt boring drill bits for drilling through metal, including steel and iron.
Boring Drill Bits Sizes
You will find boring drill bits of two sizes. The shank and the point. The shank is the part that attaches to your drill’s chuck. You should choose bits with shanks equal to or smaller than your drill’s chuck. Conventional chuck sizes are ¼-inch for light-duty drill, 3/8-inch for regular drills, and ½-inch on heavy-duty drills.
The pointed end of the bit is the business end, and drill bit sets come in a range of point sizes. 1/16-inch to ¼-inch boring drill bits are enough for most DYI projects. But for tougher drilling applications, such as construction, carpentry, or massive household reconstructions, you’ll need some larger bits. You can go for bit sizes include 5/16-inch, 3/8-inch, 7/16-inch, and 1/2-inch in those cases.

FAQs
What are boring drill bits?
Boring drill bits are specialized tools used for drilling holes in wood, plastic, and other materials. They are designed to create larger, more accurate holes than standard twist drill bits and are typically used in woodworking, cabinetry, and furniture-making.
What makes a boring drill bit the best?
The best boring drill bits are characterized by their precision, speed, and durability. They should be able to cut cleanly through the material without tearing or chipping, and should be able to withstand heavy use without dulling or breaking. The most effective boring drill bits have sharp cutting edges, are made from high-quality materials, and are designed to be used with the right equipment.
Which type of boring drill bit is best for hardwoods?
For hardwoods, it is recommended to use a brad point drill bit. Brad point drill bits have a center point that guides the bit and prevents it from wandering, which is particularly useful when drilling through hardwoods. They also have sharp, angled cutting edges that produce clean, smooth holes without tearing the wood fibers. Additionally, a forstner bit can also be a good choice for drilling large, flat-bottomed holes in hardwoods.
