and other extremely hard formations. In regions where there
is shale, limestone, or sandstone the PDC is becoming a more
popular bit, which we also repair.
WWJ: Can you describe machinery
you use on the shop floor to
repair
bits? Does part of your job
include working on the shop floor
repairing bits?
Kevin: The machinery it takes to make
and repair drill bits is either an oxy/
acetylene torch or arc welder, and
milling machine. Once the bit has been
repaired, we take it to the grinder to
shape the repair to look like a new bit.
I was on the shop floor for 32 years.
My job now consists of taking orders,
calling customers, and basic office
work. I much prefer the shop floor.
WWJ: Lastly, any
new develop-
ments in different types of bits
being manufactured in the future?
Kevin: The
only new developments
I see possibly coming down the road
are higher quality diamonds for our
PDCs and possibly a better bearing
for the tricones.
