Exploring the Differences Between CRV Bits and S2 Screwdriver Bits

Exploring the Differences Between CRV Bits and S2 Screwdriver Bits

In everyday life and various industries, screwdrivers play a crucial role in assembly, repair, and maintenance tasks. However, not all screwdriver heads are created equal. Two common materials used for screwdriver heads are CRV (Chrome Vanadium) and S2 steel. Understanding the differences between these materials is essential for selecting the right tool for the job. In this article, we will delve into the characteristics of CRV and S2 screwdriver heads, examining their respective advantages, applications, and considerations for use. Through this exploration, readers will gain insights into which material suits their needs best in various scenarios.

Different Types of Screwdriver Bits Material

If you have clearly understood the advantages of all the Screwdriver bits types, then it is time for you to know the screwdriver bits available. Screwdriver bits are distinguished based on their shape, design, and the materials they are built with. Here, we have classified the screwdrivers according to their base materials to have a clear understanding before you set out for buying.

1.Stainless Steel Bit

Most of the Screwdriver bits types you come across daily are made of stainless steel. Simply put, the material is readily available and offers good value for money, so newbies should start with stainless steel screwdriver bits. The stainless-steel screwdriver bits also come in a wide range of shapes, sizes, and attachments, so you would not need to struggle to match it with a fastener.

2.Tool Grade S2 Steel Bit

Screwdriver bits made of tool-grade steel are also quite common, and it is denoted by S2. While S stands for shock-resistant, number 2 signifies the steel’s shock grade, with seven being the highest and one being the lowest. Although these S2 steel bits are mostly composed of iron, other materials like silicon and carbon are also mixed with increasing their hardness.

3. Titanium Coated Bit

Manufacturers also produce electronic screwdriver setwith titanium bits because it is appropriate for application in riskier environments. Titanium screwdriver bits are more durable than stainless or tool-grade bits, and thus it is quite popular among professionals and business warehouses.

4.CRV Chrome-Vanadium Steel

Featuring the revolutionary CR-V Chrome-vanadium steel with nickel-plated surface, the appliance features the hardness of 52 degrees. This helps in completing the maintenance work effectively.

Advantages of Different Screwdriver Bits Material

If you have started shortlisting your options for the best Screwdriver bits types, then check out these advantages of using the same:

1.Stainless Steel

As you might know, stainless steel screwdriver bits are incredibly durable, so longevity is also guaranteed. Bits made of stainless steel are quite versatile as they would allow you to use them on diverse materials.

2.Tool Grade S2 Steel Bit

Screwdrivers are made out of top-grade steel of high hardness level of the CRV/S2 material. As such, the entire unit is highly practical and durable. The given kit is primarily used in applications like serviced electronic components like glasses, laptops, smartphones, game consoles, and so more.


Titanium screwdriver bits generally come in stainless steel bits coated with titanium to make them more combustion resistant. If you are going to work with steel appliances, you can opt for this to make it easier to penetrate steel.

4.CRV Chrome-Vanadium Steel

The CR-V chrome-vanadium steel bits help in delivering great practicality and durability to the unit. This helps in effective maintenance of the work while being assured of total accuracy.

I like the S2 better than the standard CV bits (for non-shrapnel inducing applications). They just hold up better IMO. They run a little more, but you’ll notice the difference, especially on the Phillips bits.

In conclusion, understanding the differences between CRV and S2 screwdriver heads is crucial for selecting the right tool for the task at hand.  While CRV offers excellent durability and affordability, S2 steel provides superior hardness and wear resistance, making it ideal for demanding applications.  Whether you’re assembling furniture, repairing electronics, or working on DIY projects, choosing the appropriate screwdriver head material can significantly impact the efficiency and quality of your work.

What does CrV mean on a screwdriver?

The screwdrivers are made of chromium-vanadium(CrV) steel, which provides the necessary hardness and durability.

What does S2 mean on a screwdriver bit?

S2 Steel: A specific designation of steel composition given by the AISI.  Harder than 6150, but more brittle.  Cr‐V Steel: A broad category of carbon steel with good machining and hardenability.

What is the difference between S2 and CRV steel?

Chrome Vanadium S2 Steel – S2 steel is tougher and more expensive than regular Chrome Vanadium steel.  We typically use S2 steel on bits for increased hardness levels and added life expectancy.  Chrome Molybdenum Steel – the highest quality and the most expensive grade of steel we use.
