We have the newest product A2 Steel Bits with Torsion Buffer Grooves of product information published in the 2012 Hands Tools (CENS.COM’s Guidebook to Taiwan), hope that good design can bring both quality and great business opportunities.
 
 
Re: A2 identification
We re-arrange all the elements for the combination of S2, and improve the composition of SI (improve the wear resistance and toughness), spend extra cost to achieve the specially heat- treated and get the higher tensile strength.
 
 
Re: Torsion identification
The construction of shock buffer bits when the moment the screw is locked tightly. The two deep ditches on the shaft can help reduce the level of impact.
 
A2 is more durable than S2 around 30%. Due to specially heat –treated steel to achieve higher tensile strength.
A2 with Torsion can increase efficiency 60% than S2.
