Italy Dominates in Crushning Buckets New Core Drills ... - PDWorld

Core Drills
There are many
manufacturers of
professional core
drilling systems.
Several new models
were launched last
year, but so far this
year very few suppliers
have announced
new products. Atlas
Copco has relaunched
its LCD series and
there are industry rumours
that the manufacturer
of Pentruder
is about to launch a
completely new principle
for high frequency
core drilling.

Last year saw the release of several new core drilling systems, but
with the current economic crisis there are many core drilling systems
on suppliers’ shelves waiting to be purchased. This lack of demand
has possibly delayed the release of new models, but maybe later in
the year there will be some new products on the market. However,
with the next Bauma construction equipment show scheduled for
spring 2010, manufacturers may decide to wait for the exhibition
to introduce new products.
News from Tractive and Atlas Copco
But there are indications of some activity, as PDi understands
that Tractive is developing a new Pentruder high frequency core
drilling system. The new system is expected to be officially announced
during the second half of 2009 and will be based on a
completely new principle.
Manufacturer Atlas Copco is launching their handheld
hydraulic core drilling system LCD. Although hydraulic equipment
may no longer be that popular among professional concrete
cutters, there are still applications where hydraulic devices still
work.
Operational safety, high performance and long life have
been the main targets for the designers of Atlas Copco’s two
relaunched handheld hydraulic core drills. At hydraulic torque
control reduces kickback to a low level and operators will always
be in control, even when drilling holes of 200mm diameter. For
operator comfort, the Atlas Copco core drills have low or nearly no
vibration and the core drill fits in standard drill stands, whenever
the space conditions allow.
The power-to-weight ratio is optimized compared to the
previous range. “The surprisingly lightweight core drills convince
any customer after drilling the first large hole,” says motor drills,
breakers and handheld hydraulics product line manager Jan
Byrresen. “Customers comment that they had not believed that
this is possible by hand drilling and so safe and fast. The LCD
500 and LCD 1500 is a useful core drill for any job where quick
and safe operation is needed in often difficult to access, wet and
muddy work sites.”
The drills offer spark free operations since there are no electrical
components. There is continuous lubrication and cooling
through the power pack. Lifetime of power pack and core drill
are protected through the closed hydraulic system, which prevents
dust or slurry entering the internal parts.
Handheld hydraulic core drills are universal tools for all hand
drilling jobs, even in confined spaces, where there is no room for
drill stands. Core drills are used in a wide range of applications,
including building renovation and utility works.

Recent introductions
Last year Hilti launched their compact drilling system DD120 that
can take core bits with diameters between 37-120mm. Hilti has
received a lot of credit for their line of professional drill systems and
the range contains five electric models and one hydraulic.
Also last year Husqvarna launched their DM 330, which
weighing only 13kg, features an ergonomic handle that makes
the drill easy to carry. The controls are designed and positioned to
further enhance ergonomics and to facilitate drilling.
Last year Multiquip launched their CDM1H Core Drill.
This single-speed model excels in wet drilling applications up to
75mm diameter or it can be used with Multiquip’s Cobra dry
drilling bits up to 125mm diameter. The Cobra is made specifically
for dry drilling reinforced concrete. The CDM-1H hand core
drill is ideal for electrical and plumbing jobs where operators need
to drill through walls and floors. The 11A, 115V hand-held core
drill operates at 0-1,800 rpm. This unit weighs only 20kg and
comes with an adjustable shoulder rest, a three-position handgrip,
and it’s designed with an internal water feed feature. For operator
convenience a carrying case and tools are also included.
