6 piece industrial cobalt drill bit set in a plastic case DeWalt lenght: 24-72mm diameter:2, 3, 4,5, 6, 8 mm

- 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

- The ‘no walk‘ tip allows for easier penetration of all surfaces
