Drill bits are some of the essential items for any tradesman’s toolbox. Aside from professional use, drill bits help with household maintenance as well, alongside DIY projects. But finding the best drill bits can be quite difficult, daunting even. Fear not – we are here to help. Let us guide you through everything you need to know about drill bits, and by the time you finish reading this, you will be more or less an expert on drill bits.
Types of Drill Bits
A drill bit is a cutting tool that is used for removing material from a hard surface for creating circular holes. They come in all shapes and sizes and are capable of creating different types of holes on different surfaces, such as masonry drill bits, auger bits, Forstner bits, spade bit, abrasive, non-abrasive, compatible will power tools, cordless drills, and so on. Some of the best quality drill bits include:
Spiral or Twist Drill Bits
The most common drill bits used, these are for everyday use, like making holes on not-so-tough surfaces, and can work on both wood and metal.
Named such because of their spade-like flat look, these bits are best suited for making large, deep holes in wood pieces.
The toughest drill bits are these masonry bits that can drill through concrete, cement, tiles, stone, and whatnot.
Just as the name suggests, the best wood drill bits are specially designed for drilling through wood surfaces as they don’t tear or grab the wood and provide with clean holes.

The HCBG500 Blue Granite Carbide Tip Starter Set from Bosch is a diamond-dusted carbide tipped drill bit set for a power tool or hand drill that guarantees precise drilling in hard stone, tile, and masonry. Due to its softened shank, these Carbide drill bits provide awesome gripping; while brazing for high temperature helps the bits last longer as well. Because of its milled u-shaped flutes, it can remove dust faster too.
CRAFTSMAN DRILLING AND DRIVING ACCESSORY KIT
The Craftsman Drilling And Driving Accessory Kit is a giant 100-piece drill bit set that combines pretty much every kit needed for household projects. With bits like driver bits, spade bits, and nut drivers, few drill bit sets can come close to the utility of this set. It is best suited for nearly every service, starting from plastic and wood to metal, as well as being a masonry bit.
How To Choose The Best Drill Bits
When buying your drill bits, keep in mind the following things:
The drill bits can be made out of a number of materials. Among them, the most common are High-Speed Steel (HSS), Cobalt, and Carbide. High-Speed Steel is your regular, everyday drill bits used in household and regular maintenance work. Cobalt, on the other hand, is mixed in a 5-8% solution with a base material to make it sturdier. The best cobalt drill bits are most suited for a bit tougher surfaces like stainless steel. Carbide is the toughest of the three bits, and also the most brittle. Carbide bits are used for the toughest surface, like hard metal, masonry, or concrete.
Drill Point Coatings
Drill point coatings are important not only for efficiency but for the longevity of the drill points as well. There are many coatings available in the market, for example, black oxide, TiN, TiCN, bright etc. Some of them, like TiN and TiCN, help bits last longer and also drill smoother in surfaces like stainless steel. Black oxide, on the other hand, is best for non-ferrous surfaces. Bright coating and subsequent wood drill bits are most suited for wood and plastic surfaces. Choose your coating according to your need so that you don’t regret it later.
Two basic flute designs are common – standard and parabolic. Standard ones with a 30-degree angle are the most common, while parabolic ones help remove materials from the hole for a cleaner, more precise drilling.
Drill Point Angle
Among the two basic standards – 118-degree and 135-degree, the first one is the more common one, while the second one is more suited for surfaces like stainless steel to prevent walking.
Drill Point Lengths
The Efficiency of a drill bit depends a lot on the length of the drill point. The rule of thumb is that the shorter the drill, the better the drilling. There are a number of popular drill point lengths, including screw machine length, jobber, taper, and mechanics length.
What To Consider When Buying The Best Drill Bit
Why are you buying your drill bits? Is it for professional use or casual household use? For one purpose, the best cobalt drill bits might be for you, while for another, you might need the stainless steel drill bits. You should choose your drill bit based on your intended use, or you will surely be disappointed.
The drill bits usually come in a rubber, plastic, or in some cases metal box. Before buying them, make sure the box fits your storage space. You wouldn’t want a huge box full of drill bits crowding your kitchen when all you wanted was a set for household use, right?
This is very, very important. Before buying a drill bit, absolutely make sure that they fir your drill machine. Or else, what is the point of ending up with a set of drill bits that don’t fit into your machine?
It is usually better to buy drill bit from popular brands like DeWalt, Bosch, or Black & Decker, to name a few, as they are widely available and easy to replace in case they break off.
