KEEP-NUT™
DRILLING MACHINE
MANUAL
Drill Bits
This machine is compatible with a variety of
5/8
” x 11 threaded
drill bits. Specially designed drill compatible with the Keep-nut
anchoring system are available for this unit. The standard bit
included in the box is recommended for marble, granite, quartzite
and other natural stone surfaces. We recommend specialized bits
for drilling ceramic/porcelain and specialized drill bits for glass.
A variety of core bits are available for this machine as well for
drilling faucet holes and other applications where core-bits are
used. The max drilling depth on this unit is approximately 1
1/4
” (3CM).
See below for a chart showing average drilling time to drill a
1/4
”
depth hole using the included drill bit.
For optimum drilling of porcelain, sintered and ceramic materials,
a higher RPM tool is recommended. The
KDM110
can be used to
drill accurate holes in these surfaces when using a bit designed
for these materials, but drilling times will be considerably longer
compared to granite and marble.
