suction pipe connected with the dust collection device. The automotive brake pad drilling
machine is scientific and simple in structure, dust is removed at the drilling hole of the first dust
removal device, secondary dust removal is carried out through the second dust removal device
below the drilling hole, the dust removal effect is good, and the environment is prevented from
being polluted.
CN103537729A discloses a handheld drilling machine with a dust removal device. The handheld
drilling machine comprises a drilling machine shell, a drill chuck, a drill bit and the dust removal
device. The dust removal device comprises a dust collection base, an aligning rubber sleeve, a
fan blade and a dust collection box, wherein the fan blade is installed in the dust collection base
through a bearing, an inner circular conical surface opened backwards is arranged on the fan
blade, the aligning rubber sleeve is arranged on the drill bit in a penetrating mode and rotates
along with the drill bit, the circumference of the aligning rubber sleeve is an outer circular
conical surface, and the outer circular conical surface can be attached to the inner circular conical

surface of the fan blade to drive the fan blade to rotate; the fan blade sucks external air in or
exhausts internal air when rotating, an air channel used for controlling the flowing direction of
the air is formed in the dust collection base or the dust collection box, and through the flowing of
the air, dust generated in the hole drilling process is thoroughly brought into the dust collection
box. The handheld drilling machine is reasonable in structure, small in size and low in cost and
can prevent the drill bit from driving the fan blade to jitter, and the dust is removed more
thoroughly.
US20020154960A1 discloses A power drill includes a main body that is divided into a power
chamber for mounting a driving motor and a vacuum fan therein and a dust collecting chamber
for mounting a dust-filter therein. A hose is connected to a front inlet of the dust-collecting
chamber with a front suction inlet of the hose fixed to a retractable hose holder to closely locate
below a bit of the power drill. When the motor is turned on, it drives the bit to drill a hole and the
vacuum fan to rotate at the same time to produce a suction force in the dust-collecting chamber,
so that any dust produced during the drilling operation is immediately sucked into the dustcollecting
chamber via the hose and then trapped in the dust filter that could be removed from
the dust-collecting chamber and cleaned for use next time. The retractable hose holder gradually
and elastically retracts when the bit drills the hole, so that the suction inlet of the hose is always
kept closely below a joint of the bit and the drilled hole to effectively suck any produced dust.
EP 91105845 In a hand-held drilling machine with a combination chuck for the alternative
chucking of round-shank or slotted-shank tools, the insertion, the automatic locking and the
holding of slotted-shank tools is to be simplified and operating errors are to be eliminated. This
is achieved by the receptacle (35) for slotted-shank tools (10) being arranged behind the
chucking area of the jaw chuck (16) as viewed in the axial direction from the insertion side (18)
of the tool holder (8). This type of construction permits the attachment of means (22) for the
rotary driving of the inserted tool. If a hammer drill is equipped with the tool holder (8)
according to the invention, the concentric-running properties in round-shank drill bits are thus
also considerably improved thereby.

housing (2), a second striking mechanism (20) is arranged for producing axial impacts, the axial
impacts of which have an impact energy and an impact frequency different from the impact
energy and the impact frequency of the axial impacts produced by the first striking mechanism
(16). The drilling or chiseling tool bit (7), clamped in the chuck (6), can be acted upon with axial
impacts produced either by the first (16) or the second striking mechanism (20) or by both
striking mechanisms together. The axial impact striking, mechanisms (16, 20) can also be
switched off completely for use in wood or metal.
