If, despite the abundance of possibilities, you still can’t locate an HDMI cable that works for you, don’t worry. Here is a list of 10 often-used alternative terms for 2022. After many hours of study, these words were finally put together. Come on, then!

What is Hardened Steel

By “hardened steel,” we mean steels with a moderate to high carbon content that has undergone heat treatment and tempering procedure before being drilled. The properties of hardened steel include resistance to wear, corrosion, and abrasion. 

Hardened Steel

These days, hardened steel is the go-to material for many mechanical engineering, power generating, and transportation applications. So the most significant metal drill bits on the market may be optimized for speed while working with softer carbon steels or made specifically for use with hardened steel.

Which Types of Drill Bits for Hardened Steel

Using a drill bit composed of stronger materials is important when working with hardened steel. Drill bits made of carbide are the toughest on the market and can even drill through steel that has been hardened. However, titanium and cobalt drill bits can be substituted if the former is unavailable. It will take much longer to drill with either of these than with a carbide drill bit.


Carbide drill bits are the hardest on the market and work best for drilling through hardened steel. Tungsten carbide is a tungsten-carbon alloy. Steel with a carbide tip is the most common material for carbide drill bits.

Carbide-tipped drills are the toughest, but you should use caution while working with them since they can break easily. Their high strength makes them useful in a wide variety of industrial settings. They are so powerful that they can even slice through steel.


There is no pure cobalt in cobalt drill bits. Instead, they comprise steel with a small amount of cobalt added to it, often between 5 and 7 percent.

Titanium Coated

Bits of high-speed steel coated in titanium nitride are known as titanium drill bits. Drill bits coated with titanium are far more durable, heat-resistant, and wear-resistant than their steel counterparts.

The steel bit is shielded and preserved by the ceramic material titanium nitride (TiN), which is particularly effective when drilling tough steel.

Drill Bit Materials


These drill bits are constructed from solid cobalt and high-alloy steel. Extremely high temperatures and heavy use are no match for these components. For all those reasons and more, these bits were explicitly developed for use with metal since they can cut through any steel or metal.

Steel with a High Rate of Velocity

Vanadium and tungsten are used in the production of these drill bits. As measured by the Rockwell hardness scale, they are 60 or above. The twist bits get their name from how the tops of the bits resemble a twist screw.


Although they are constructed of steel, the carbide tip is what gives these bits their name. As a result of their durability, they find widespread usage in commercial and manufacturing applications. Most of the time, they can even slice through metal and other rigid materials.

Diamond Coated

When drilling through extremely tough materials, nothing compares to the performance of the diamond bits. In addition, the diamond-tipped bits are backed by high-speed steel, making this set long-lasting.

How to Determine Which Drill Bit Is Appropriate for Hardened Steel

How to Drill Hardened Steels 

Make Sure You’re Using the Proper Tools

Bits designed for hardened steel are what you need. Standard bits are prone to breaking or failing to produce the desired outcomes. You’re using the wrong one if the bit doesn’t taper smoothly. Bits should be high-density and constructed of high-speed steel, at the very least.

Lower the Thermostat

The temperature must be kept low since heat and hardened steel don’t get along very well. This might necessitate applying minimal oil to the metal to keep it from becoming rusty. If the tool you’re using doesn’t already have a built-in lubricant (such as the ones made for hardened steel), then you should use the oil.

Drilling at fast speeds is also not recommended since the more work it has to perform, the hotter it will get. Instead, working slowly and steadily with the tool is recommended, and bits coated with titanium are often more heat resistant.

Noise and Vibration Reduction

When working with hardened steel, you may run across many problems. For example, they’re vulnerable to chips, have trouble staying together, and often have to break off and leave the group. But if the part is stable, nothing like that will occur, leading to a much better outcome.

Get the Tool to Room Temperature

It’s best to let the tool cool down after usage, as hardened steel doesn’t like being hot and overheated tools can cause damage. In addition, it’s essential to limit the length of each drilling session so that you can keep working without stopping because of heat.

Care About Safety

Any drill bit has the potential to snap at any time, posing a serious hazard. This implies it has the potential to cause blindness by directing metal fragments directly toward the eyes. This is why protective eyewear is a must. As we said before, it is crucial that the part you are working on is secure and clamped down.

Safety Tips for Drilling Hardened Steel

Choose the right drill for the job

The first step in efficient drilling is selecting the appropriate drills and drill bits in terms of size, kind, and number. The Ronix Tools Company can supply you with various drills, including electric corded drills, corded impact drills, corded impact wrenches, and so on.

Remember to dress for safety and use appropriate protective equipment

Wear protective eyewear whenever you drill. Drilling creates dust that can be inhaled. Hence respirators are recommended. Gloves are great tools and might be useful if they fit properly. Invest in a quality pair of gloves to safeguard your hands.

Ensure the Drill Chuck Is Nutted Down Nice and Tight

The chuck ensures the drill runs smoothly and securely when not in use. The drill bit won’t turn because the chuck is loose. Before tightening the chuck, insert the drill bit. Once you hear a single click, you know the chuck is tight enough. You know the drill bit is securely in place when you hear that last click.

Stretch the Work to Its Maximum

Clamp your workpiece down securely before you drill through it. Hold the drill firmly with both hands and at no point should the piece be held in one hand when drilling. Understand the different kinds of drill bits.

Do Not Apply Excessive Force to the Drill

The motor should take care of most of the drilling work. If you apply too much force, the drill can slip, or you might damage the motor. That’s why adjusting your drill speed and pressure for different materials is so important. Making rough holes with wood drill bits is possible using a lot of force and speed. However, tearing might occur if you use excessive force. Drilling a hole in the wood with less splintering requires going a little lower and keeping the bit as straight as possible.

Do Not Wear Jewelry or Flabby Clothes When Drilling

Jewelry, scarves, and long, loose sleeves should not be worn when using a drill. The drilling process might pose a risk if the dangling objects were to be grabbed and pulled. Therefore, if drilling, you should roll up your long, loose sleeves and tie back your thick, flowing hair.

Mark the Drill Site

Since the drill might slip on surfaces like metal, glass, etc., hammering a nail into the work area and marking it is a good idea. Next, bore a hole with a more precise instrument. After that, drill a hole with the primary bit. You’ll have more control and precision when drilling. Alternatively, secure a piece of paper to the tile at the appropriate spot to prevent the drill from sliding.

Turn Off the Drill If Water Gets on It

If water enters your electric corded drill, unplug it immediately to avoid electric shocks and possible equipment failure. Then, use a Ronix heat gun or a conventional clothes dryer to dry it. Please let a cordless drill’s battery drain and place it somewhere dry.

Use a Drilling Platform

The drill’s foundation is a support structure and a reference point. A drill base is used when drilling into a complicated surface. If drilling straight is difficult, a drill base will be very helpful.

Never Hold or Hang a Cabled Drill by the Cable

A short circuit or broken wire might arise from transporting or holding a corded drill while the cable is connected.

All necessary safety measures for drilling operations have now been covered.


Which drill bit is best for hardened steel?

You’ll need a drill bit made of cobalt to drill through steel or other rigid materials. Drill bits are typically constructed of an alloy that includes between 5% and 8% cobalt. As a component of the steel alloy, cobalt ensures that the bit’s durability is maintained without the need for a protective finish.

Will a carbide bit drill harden steel?

When drilling through hardened steel, nothing but a carbide bit will do. Drill bits made of titanium and cobalt can be used in their place if the former is unavailable. Both of these bits, however, will require more time to drill than a carbide drill bit.


The above factors were the basis for selecting the best drill bit for hardened steel. How final is this? Certainly not! In order to provide you with the most up-to-date and relevant information, we update our site frequently.
