OnlineToolReviews.com - GMC (Global Machinery Company) HD2G250M Magnesium Hammer Drill - Detailed Review
Rubber overmolds are also found wrapping around the main handle, around the top
rear end of the drill body and around the auxiliary handle. They provide slip
protection, user comfort and a little degree of tool protection against bumps, knocks
and small drops!
The front auxiliary handle is adjustable through 360 degrees around the tool and
provides a support handle for harder drilling tasks, or just for holding the tool for
improved tool balance. A depth stop rod is incorporated into the handle and, unlike
most hammer drills, it has a slight bend at the chuck end. Why? Basically, having
the bend in the rod positions the depth stop rod end closer to the center of the drill
chuck, and hence closer to the drill bit. When drilling into materials that are not as
thick (width-wise), in some instances, standard straight depth stop rods might not
actually contact the same surface you are drilling into. With a bent end rod, there is
much more of a chance to engage the end of the rod with the same surface as you
are drilling, hence making accurate depth drilling possible in more instances. You can
release and adjust the rod by rotating the auxiliary handle, and secure the rod again
by twisting the handle in the opposite direction.
That about covers the features... Now, in terms of sound level in use, the manual
states the rated sound pressure level as 91.7dB. Anything above 80dB definitely
necessitates the use of ear protection, even for short duration use, so grab those
pair of muffs and cover those ears. Quality ear muffs have been proven in many
tests to be more effective than ear plugs, so be sure to use the right gear to protect
your hearing.
Tool Weight is 2.7kg. Not overly heavy for a hammer drill, but not a drill you will
want to be using for hours on end. Thankfully, you probably will not need to in most
cases, unless you are in a trade requiring continuous use of a hammer drill
throughout the day.
Case and Accessories
The drill ships in its own molded carry case, but perhaps one of the best selling
points of this drill is the 250 piece accessory kit that it comes supplied with. Most of
the accessory count is made up of driver bits, covering just about every driver bit
type known to man, plus there are multiples of each type, and each size of that type
as well. Driver bit types include:
●
Square Drive
●
Hex Drive
●
Slotted
●
Philips
●
Star type (6-point)
●
Pozi-Driv
●
Philips and Slotted in mid-length shanks
●
Hex nut drivers from 5mm to 13mm in 1mm increments.
The drill mode slide switch (left) and
chuck lock button (right) on top of tool.
Main handle showing trigger, speed
selector wheel on trigger, trigger lock
and forward/reverse rotation slide
switch.
Ergonomic design with plenty of rubber
overmolds for comfort.
