PAGE 12 — CDM1H CORE DRILL • OPERATION AND PARTS MANUAL — REV. #7 (10/12/17)
GENERAL INFORMATION
APPLICATION
The MQ CDM1H Hand-held core drill is designed for
multiple small to medium core drilling applications. Its
lightweight signature and extending shoulder support
provides the operator a stable and flexible platform to
achieve excellent drilling results in masonry, cured concrete
and asphalt.
The unit comes as a complete package ready to accept
many types of core bits, and provides (2) adapters so
that the drill motor can easily marry up to bits that accept
either 5/8”-11 or 1/14”-7 male thread. The drill drive shaft
is a male 18mm, and the adapters will be necessary for
most core bits.
The drill is powered by an 110VAC 10A universal electric
motor with an integrated clutch system.
THE CDM1H COMPRISES
Hand-held power drill
Carrying Case
Two core bit adapters
Water kit
Tools for bit connection/removal
Operations/Parts manual
OPERATIONS
For successful operations; and like any diamond grinding
tool, the CDM1H requires the proper diamond core bit to
match the material. For core bit options, this drill performs
best when the operator selects the correct diamond core
bit, and allows the bit to grind at an optimum pace. Pushing
the drill past its designed engineering will not expedite the
grinding process.
Regardless of the type of core drill bit selected, it is essential
to utilize the water kit that comes in the kit. The water kit
MUST BE connected to the drill motor prior to operations.
From the water delivery method, a common garden hose
can easily be connected to the drill. The water kit’s knife
valve provides a means to control the liberal amounts of
water necessary to cool the core bit.
WARNING
Adherence to the OSHA 2017 Ruling governing
Occupational Exposure to Respirable Crystalline
Silica, requires that all core drilling operations
MUST
BE conducted with an integrated water delivery system
that feeds water to the core bit.
