OnlineToolReviews.com - GMC (Global Machinery Company) HD2G250M Magnesium Hammer Drill - Detailed Review
Plus, there is a quick-change hex extension bit and an assortment of drilling bits
including 6 x brad point drill bits (2 of 4mm, 5mm and 6mm) and 12 x standard
twist drilling bits of various sizes. Each bit has its own molded location in the case,
presenting an impressive array of driving and drilling accessories. What seems
missing however are some masonry drilling bits. After all, this is a hammer drill
designed somewhat for masonry work, so a few masonry bits would have rounded
out the collection. Nonetheless, buying all these bits individually would pretty much
cost as much as the drill alone anyway, and possibly much more, and the driver bits
and brad-point bits seem to be of good quality. The twist drill bits are average at
best however.
In Use
Like most hammer drills, the HD2G250M is very much nose heavy when held in one
hand via the main handle. Grasping the auxiliary handle with your other hand
provides the weight distribution and balance needed for accurate and controlled
drilling. In the hands, the drill feels very comfortable, but solid at the same time.
The back end of the tool (above the main handle) can be comfortable gripped with
index finger wrapped around the opposite side of the body because of the ergonomic
shape of the upper rear housing. The rubber overmolds here add comfort as well.
When powered up, the drill exhibits vibration that seems on par with any other
hammer drill of this size and power and the chuck appears to run quite true on our
test unit, which should ensure accurately dimensioned drill holes, and in testing, this
was indeed the case. As mentioned above, the rubber covered chuck was very
comfortable to use, and I will repeat that statement again here as I feel it is a major
practical use feature. I haven't come across a more comfortable keyless chuck yet. If
only it was of the ratcheting variety, it would be almost priceless!
For our tests we drilled into softwood, hardwoods and masonry. In softwoods the
drill handles just fine, even with larger spade bits and holesaws attached. Power is
no problem when drilling the softer timber species. In hardwoods the drill performs
well with most smaller bits. When using larger diameter bits, you really do need to
use the sharp high quality bits to get the job done right. Large dull bits in dense
material did strain the drill at times during our tests. For masonry work, the drill
preformed reasonably well when set on hammer mode. Obviously it will not drill into
concrete as well as a rotary SDS style drill does, but for around the house or DIY
masonry work, it will do the job. Just take it slow and clear the drilled hole regularly
to ensure a good result and preservation of your masonry bits. Correct use of the
gear settings will also ensure performance in varying tasks.
Conclusion
At the price point this drill is offered at (AUD$99) it is obviously not designed as a
heavy commercial/trade use hammer drill. It is designed more for the light/medium
duty homeowner, DIY enthusiast or home renovator, and for this class of user, the
drill would suit. In terms of value for money, the drill excels with part-magnesium
body, ergonomic designs and that great selection of drill and driver bits! Plus the drill
comes with GMC's standard 2 year replacement warranty should you have a
problem. Overall, not a bad option as an all-around drill for light/medium duty use
