- The 8% cobalt content maintains a sharper cutting edge and delivers a 4X longer life versus DeWalt Black Oxide bits. - The optimised tip and flute geometry delivers 2X the penetration speed, versus DeWalt Black Oxide bits, removes material faster and reduces heat build up. - The stronger central core delivers 2X the resistance to breakage versus DeWalt Black Oxide drill bits.
Open Ended Spanner Wrench manufactured in chrome vanadium steel, with chrome and polished finish, rounded corners that provide a greater contact area with the bolt and torques for hexagonal and grooved sides, relieving the torque on the ends, thus preventing screws and nuts from stripping quickly.
