詳細規格及用途描述
Innovative A-2 Steel/Torsion-buffer Grooved Screwdriver Bits
* Of A-2, specially heat-treated steel to achieve higher tensile strength
* With consistently-hard edges for 30% longer life than S-2 ones
* Innovative, dual torsion-buffer grooves absorb, minimize impact from sudden locking
* Torsion bits are some 30% more durable than typical counterparts
* A-2 steel bits with torsion-buffer grooves are 60% more durable than typical counterparts!
