Demolition Hammer with Brushless Motor H41SE
GREATER WORK EFFICIENCY
-
Lightest in its class*1
Employing an AC brushless motor and minimizing the weight of components, this product provides better control for accurate and total demolition, and less fatigue for extended periods of work or during operation in horizontal positions.
-
Best Demolition Performance in its class*1
Operating condition: Demolition in the downward direction
Material: Concrete panel with compression strength of 2,352N/cm2 (240kgf/cm2)
The numbers in the chart are relative values.
- As of February 2019, among 5kg class demolition hammers for hexagon bit made by leading power tool manufacturers. (Survey by Koki Holdings)
- Weight according to EPTA procedure 01/2003 (incl. 0.3kg side handle).

Our Original Brushless Motor Technology
► No wearing parts (carbon brushes, commutator, rotor coil)
► Our original compact controllerLong Lifetime, Maintenance-Free
The brushless motor offers a significantly extended product life cycle by eliminating trouble including armature burnout, layer short or commutator wear even in severe work environments. Besides, no carbon brush replacement is required.
Compact, Lightweight
Compatible with engine generators*
-
Equipped with our original, compact and high efficiency inverter circuit, the hammer works with an engine generator that doesn’t have an on-board inverter.
- When using the brushless motor tools with engine generators whose output voltage can be adjusted, excessive voltage could cause these tools to fail.
Stable operation even during voltage drop
-
The brushless motor runs cooler, and its performance isn't affected as much by voltage drop from long extension cords on site. This vastly improves electrical efficiency.
INCREASED COMFORT & EASE OF USE
-
①Easy to Hold
Resin cylinder case cover for better control in various applications.
②Less Fatigue
The low vibration handle comprises an upper unit with rubber dampers and a lower unit with a hinge. It provides high vibration absorption effect for added user comfort.
③Impact Rate Selector Switch
Push-button, constant speed control with variable speed allows the user to adjust the impact rate according to applications.
④Soft Start
Reduces reactive force on the tool body and the bit at the startup.
⑤Idle Hammering Prevention
