These 2-piece step drill bit sets are no exception!
Each drill bit features a titanium nitride coating to
withstand very high-temperature drilling applications
for extended periods of time. They're ideal for drilling
repetitive holes in steel, copper, brass, plastic, Plexiglas
and other materials.
The sets include an 11-step bit (1/4 in. to 1 3/8 in.) and
a 12-step bit (3/16 in. to 7/8 in.).
