We use S2 tool steel for the bits in our Reflex and Range torque wrenches, among other tools. It's more expensive but it is the right choice for our tools. Here's why.

S2 steel is a type of tool steel known for its exceptional toughness and resistance to breakage. Primarily a carbon steel alloy, it contains small amounts of other elements like chromium, molybdenum, and vanadium.

What we want in our driver bits and hand tools is tough, durable material that can be machined to precise working tolerances. And material that will stand up to years of hard use in high-stress applications. S2 steel fits the bill, maintaining precision fitment in fasteners while lasting for years of use.

The key characteristics of S2 steel are why it's perfectly suited for driver bits.

• Extreme Toughness: S2 steel is renowned for its ability to withstand high impact forces and vibrations without fracturing.   
• High Hardness: Achieves excellent hardness when properly heat-treated, providing good wear resistance.   
• Good Bendability: Can be bent significantly before breaking, making it suitable for applications where flexibility is important.

S2 steel is an ideal choice for applications that demand a combination of strength, toughness, and wear resistance. It is ideally suited for hand tools, providing durability and longevity in demanding applications.

So the next time you're looking for a new tool or a fresh bit set to liven up your kit, look for quality materials. S2 tool steel is our choice for bringing professional quality to everyday mechanic's work.
