The 1/4" Hexagon Screwdriver Bit - ACR®, with an interface size of approximately 6.35mm, combines the versatility of traditional hex bits with ACR® patented technology to deliver upgraded performance. Compatible with various tools such as electric screwdrivers and drills, its quick-release design allows seamless transitions between different tasks, significantly boosting productivity.
At the core of ACR® technology is a unique head treatment process that optimizes the fit between the hex structure and screw slots, enabling more efficient torque transmission. Compared to standard hex bits, the ACR® version reduces slippage by up to 30%, ensuring precise force application during tightening or loosening operations and minimizing the risk of screw stripping. Additionally, this technology enhances wear resistance, extending the bit's service life.
Constructed from S2 alloy steel or chrome vanadium steel and processed through quenching and tempering, the bit exhibits exceptional hardness and toughness. Paired with ACR® technology, it maintains consistent performance in challenging environments such as humid or dusty conditions. Widely used in furniture assembly, electronics repair, and small machinery maintenance, it is the preferred choice for professional technicians and DIY enthusiasts alike.
