Rotary Hammers 22mm (7/8 " ), 24mm (15/16 " )
CONCEPT AND MAIN APPLICATIONS
H
The subject models are successors to the current models called " 2kg Rotary hammer " .
HR2230, HR2460 and HR2460F have two operation modes (Rotation only / Rotation
with hammering).
HR2470, HR2470F, HR2470T and HR2470FT have three operation modes
(Rotation only / Rotation with hammering / Hammering only).
W
The letters of the model name show the features as follows;
Dimensions: mm ( " )
HR22 or 24: Capable of drilling 22 or 24 mm diameter hole

About 4 times as tough as the current by;
Increased Durability 1) modification of impact bolt and its contact parts.
2) change in position of interia-air outlet hole and enhancement of sealing to prevent inside
grease from leaking.
3) zigzag varnish to Armature.
40 Different Bit-angle Setting (exclusively for HR2470,
HR2470F, HR2470T and HR2470FT)

Rotation Reversing System
Using Brush Holder Unit
Features the following advantages:
Service life of carbon brush is about 2.7 times
as long as that of HR2450 series.
Maintenance is easy because of the simple
wiring structure compared with HR2450 series.
Reverse rotation speed is as fast as forward
rotation speed.
The above system enables the machine to meet
electromagnetic compatibility-requirement without
the stroke limiter of trigger in reverse rotation.
