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.
