13pc T Handle VDE Screwdriver Set in Zipper Bag

 

 

Insulated screwdrivers are a specific type of screwdriver made to be used in high-voltage and electrified applications. The entire shank and handle of an insulated screwdriver are typically wrapped in insulating material, with the exception of a small area of the exposed metal head. This effectively reduces the risk of high-voltage arcing and the contact of live metal with the environment, enhancing the safety of live operation. Generally, insulated high-voltage screwdrivers have a 1,000 volt label.

 

Distinctions between various screwdriver materials

Generally speaking, the bits of good quality screwdrivers are made of spring steel with high hardness. The basic standard is that it is hard but not brittle, and tough in hardness. If the opening of the screw head becomes bald and slippery, at this time, you can use a hammer to hit the screwdriver, pick the slot of the screw deeper, easy to unscrew the screw, at this time, make sure that the screwdriver should be unharmed. Life screwdriver is often used to pry things, so this time requires a certain toughness of the screwdriver does not bend or fold. In general, we hope that the hardness of the head of the screwdriver is greater than HRC60, and to make sure that rusting is difficult. The quality screwdriver will stop functioning properly if it is prone to rusting.

1. Chromium-Molybdenum Steel (Cr-Mo): This steel is an alloy of chromium, molybdenum, iron, and carbon that is more expensive but has excellent impact resistance, hardness, and toughness. It is typically used in the manufacture of top screwdrivers and small hexagonal spanners.

2. Steel with chromium-vanadium (Cr-V)
This material is great for making screwdrivers, spanners, and other tools because of its good strength and hardness. It is a less costly alloy made of the metals chromium and vanadium that is frequently used to make screwdrivers.

 

3. Steel made of carbon (Carbon steel)
The benefits of carbon steel include high strength and hardness, while the drawbacks include low toughness. Carbon steel does not include other particular elements and has a carbon mass fraction of less than 2.11% of the class of steel. Although this steel is frequently used for several general-purpose tool materials, it is not appropriate for use as a screwdriver.

4. S2 Steel for Tools
Excellent impact-resistant steel, this alloy is used to make high-hardness hexagonal wrenches, screwdrivers, and other tools. This steel is heat treated to provide the tools it is formed of a sufficiently high hardness. In addition to having some strength and toughness, it resists abrasions well. For the real purpose of choosing and using screwdrivers, it is inferior than chrome vanadium steel.
