COBALT SPOT WELD DRILL BIT – RETRO X

$10.69

Our 8mm spot weld drill bits are used to drill out existing spot welds within the auto industry. Cobalt steel chosen to withstand drilling hardened steels and to ensure longevity. Generally cobalt will outlast standard high speed steel x 4.

Choose between MOD FORM and RETRO X:
MOD FORM has the drill cutting flute ground to ensure a shallow cutting surface on modern metals.
RETRO X has a slightly deeper flute to accommodate older vehicle welds. It’s cutting depth is perfect for slightly thicker metals.

BLACK OX or COBALT?
BLACK OX drill bits are made using the highest grade HSS available. We manufacture industrial quality bits used for heavy engineering and fabrication or trade work. BLACK OX drill bits have flex, COBALT does not. COBALT drill bits are designed for drilling stainless steels and other hardened steels with precision i.e. tapping. Due to their unique hardness COBALT will not flex and is not forgiving especially if using a battery drill. BLACK OX is flexible and designed for battery drilling, even in hard steels. BLACK OX is not recommended for tapping and precision.

BLACK OX – General fabrication, all trade commercial work, battery drilling, plate steels. Excellent lubricity, remains sharp, good flexibility, 135 degrees, hardened plastic cases.
COBALT – Stainless steels, hardened steels, tapping, precision drilling. Can be used with battery drills however less forgiving due to hardness of cobalt steel.
