How to choose the
best drill bits for hardened steel
What is the Purpose Of Drill Bits For Hardened Steel?
Drill bits are small metal tools which are designed to be attached to drills. There are many different types of drill bits available, each suited to specific applications. Some common uses include drilling holes into materials such as concrete, masonry, brickwork, plasterboard, drywall, timber, plastic sheeting, etc., while others are specifically designed for cutting metals (e.g. stainless steel).
Types of Drills & Drill Bit Types
There are two main types of drills – corded and battery-operated. Corded drills require a power source connected via a cable, whereas battery-powered drills operate using rechargeable batteries. Both types of drills are suitable for most general DIY projects, although corded drills are generally preferred due to their greater versatility.
Corded vs Battery Powered
Battery powered drills are typically lighter and easier to handle than corded models, making them ideal for light duty jobs where weight isn’t important. However, corded drills are capable of delivering higher torque levels, meaning they can cut harder materials faster. As a result, corded drills are commonly favoured for heavy duty applications such as plumbing, carpentry, construction, and demolition.
Common Uses For Drill Bites
The following list includes examples of typical applications for both corded and battery operated drills. Note that these lists aren’t exhaustive – there are literally thousands of possible uses for drill bits!

The Importance of Purchasing Quality Drill Bits For Hardened Steel
Drill bits are essential tools for most DIY projects. However, there are many types of drill bits available today, each designed for different purposes. Choosing the right type of drill bits depends largely upon the material being drilled into. In addition, choosing the correct size drill bit depends on the diameter of the hole required. Here we discuss the benefits of using hardened steel drill bits versus regular drill bits.
Benefits of Using Drilled Holes Made From Hardened Steel
Hardened steel drills last longer than standard drills because they resist wear caused by drilling holes in hard materials.
They are stronger than normal drills because they contain harder metal particles within the matrix of the drill body.
Because they are harder than normal drills, they cut faster and require fewer revolutions per minute (RPM) to achieve the same depth of penetration.
Hardened steel drills are easier to sharpen than normal drills.
How To Select The Right Size Drill Bit
There are two main factors which determine the size of the drill bit needed for a particular project. First, the diameter of the hole required determines the size of the drill bit needed. Second, the hardness of the material being drilled affects the durability of the drill bit. Generally speaking, softer metals require smaller drill bits while harder metals require larger drill bits.
Types of Drill Bites Available Today
Today, there are three main categories of drill bits available. Each category has its own advantages and disadvantages. We’ll briefly describe these categories here.
Standard drill bits – Standard drill bits are typically made from high carbon steel. They are inexpensive and easy to obtain. Because they are cheap, they are widely used for general household applications. However, they lack strength and durability compared to hardened steel bits.
Hardened steel drill bits – These drill bits are generally made from stainless steel. They are strong and durable, making them ideal for heavy duty applications. However, they are relatively expensive and difficult to obtain.
Diamond drill bits – Diamond drill bits are manufactured from synthetic diamonds. They are extremely sharp and very effective for cutting tough materials such as concrete and stone. Unfortunately
Drill bits are very important tools which are used in drilling holes into hard materials. There are many types of drills available in the market today. Each type has its own unique features and benefits. So, choosing the right drill bits is essential for getting good results. Here we discuss some of the most common features to be considered while purchasing drill bits.
The size of the drill bits depends upon the material being drilled. Smaller sized bits are generally used for softer materials whereas larger bits are required for harder ones. Generally speaking, smaller bits are easier to handle and control. However, bigger bits give better penetration rate and hence faster drilling speed.
There are different kinds of shape available in the market. Round shaped bits are commonly used for drilling round objects. Whereas square bits are preferred for drilling flat surfaces. Other shapes include triangular, hexagonal etc.
Different types of materials are used to manufacture drill bits. Some of these materials include carbide, tungsten carbide, ceramic, stainless steel, titanium etc. Carbide bits are widely used because of their high hardness and durability. Ceramic bits are popular among DIY enthusiasts due to their ease of handling and low weight. Stainless steel bits are mostly used for heavy duty applications where toughness and strength are needed. Titanium bits are lightweight and easy to maintain.
Depending upon the application, there are two main finishes available in the market – matte finish and polished finish. Matte finish bits are best suited for general purposes whereas polished bits are ideal for finishing operations. Polished bits are typically smoother and require fewer sharpening cycles compared to matte finished bits.
Most manufacturers claim that their products last longer than others. But, it’s always wise to check the warranty period offered by each manufacturer. Most companies offer warranties ranging between 1 month to 2 years depending upon the product quality and brand name.
It is advisable to go for cheaper options initially. As long as the quality remains consistent, you can upgrade later. Buying cheap drill bits does not necessarily imply poor performance. Many brands sell affordable
Drill bits are essential tools for most jobs around the house. Whether you’re drilling holes into drywall or making repairs to your car, there’s no way you could complete these projects without using a set of drill bits. However, choosing the right type of drill bit isn’t always easy. There are many different kinds available, each designed for specific applications. Here we take a closer look at three common types of drill bits and explain why you should be careful which ones you select.
The standard bit is probably the most commonly found kind of drill bit. Standard bits are typically made from carbide and tungsten carbide (WC). Carbides are harder materials than WC, meaning they cut faster and last longer. Tungsten carbide has been proven to withstand high temperatures, while still being able to hold its shape. As a result, standard bits are ideal for drilling metal objects, including hardwood floors and concrete walls.
Hardness Shaped Stone (HSS) bits are another popular choice among DIY enthusiasts. HSS bits are manufactured from special stones that are heated and shaped into a variety of useful forms. One example of an HSS bit is the hexagonal stone bit. Hexagonal bits are perfect for cutting sheetrock because they allow you to create straight lines quickly and efficiently. Another advantage of HSS bits is that they are extremely durable. Unlike standard bits, HSS bits aren’t prone to breaking during long periods of continuous use. In fact, HSS bits are known to last decades!
Pilot bits are smaller versions of regular drills. Pilot bits are generally used for small precision cuts. Because pilot bits are smaller, they require less force to operate. As a result, pilots are easier to control and maneuver. Additionally, pilot bits are safer than larger models since they reduce the risk of injury caused by flying shrapnel. Finally, pilot bits are cheaper than larger models. While they may seem like a good idea, pilot bits are only recommended for light duty uses. Heavy duty operations such as drilling large holes or removing old nails are best left to professional contractors.
