No Hammering
while Idling
ensures machine's long life.
Torque Limiter
when drill bit hits against
reinforcements,
Torque Limiter operates
to stop.
Change Lever
in protected position
for reduced possibility of
breakage even if the machine
is carelessly down to rest.

(HR4511C and HR4510C)
Extremely Comfortable
Easy and Very Comfortable
Easy and Comfortable
Easier to manage the exposure of vibration to body.
Easy operating Slide Lock-on Switch for hammering.
Easiest to manage the exposure of vibration to hands and arms.
Slide Lock-on switch leaves operators' fingers out of effort
to keep pulling trigger for long hours when hammering.

Comparison of Vibration level* and Time to reach
ELV (Exposure Limit of Vibration)**
*It is known as the tri-axial value and value at Directive of A(8).
**It means the maximum amount of vibration that an operator may be exposed to on any single day.

Longer life of Carbon brushes
features twice as long as that of Predecessor
model by employing large carbon brush.
Auto Cut-Out
Carbon Brush
protects commutator and
indicates time for
maintenance.
Rubberized Soft Grip
provides more control and
comfort while minimizing
hand fatigue and pain.
