Rotary Hammer 23mm (7/8")
Combination Hammer 23mm (7/8")
HR2300 is a 23mm (7/8") 2-mode rotary hammer while HR2310T is
a 23mm (7/8") 3-mode combination hammer with quick change drill chuck.
Both models are adapted for SDS-PLUS bits, featuring compact and
lightweight design, enhanced comfort and better control with ergonomic handle.
HR2300 series models are available in the variations listed below, including
HR2600 and HR2610 series models developed on the same concept.
For information of HR2600 and HR2610 series models,
see “TECHNICAL INFORMATION” of each series.

Features and benefits
*The same advantages as HR2470 series models
40 Different bit-angle settings *
The bit-angle is adjustable
without chisel adapter.
Increased repairabilityIncreased repairabilityLess bit wobbling
compared with HR2470 series models The repairability of clutch cam is
drastically increased by simplifying
the mechanism of operation mode change.
High durability *
ergonomically designed to:
• give maximum power thrust.
• provide a sure and comfortable
grip in any operation; overhead
application, drilling with palm-up
or palm-down grip.
Easy-to-grip handle
Quick change drill chuck (keyless)
(HR2310T only)
*
*
Torque limiter
One-touch sliding chuck
for easy bit change
*
Redesigned accessories
obtained by making bit guide portion
9mm longer than that of the current models
Easy depth adjustment
Depth gauge can be adjusted
with a single motion.
Rubberized soft grip
provides enhanced comfort and control.
*
Plastic carrying case
Large carrying handle
Large latches
• Easy to transport with large carrying handle
• Easy to open with large latches
• Stackable with other plastic carrying cases
of the same size or different size
Dust cup
Higher visibility of the bit tip
obtained by transparent cup mouth
Connectable with the hose of
Makita vacuum cleaner without joint parts
• With Makita vacuum cleaner, this dust cup can efficiently
extract dust and debris in a wide range of drilling operations;
from overhead to vertical downward applications.
• Also can be used like the current dust cup by plugging
the suction port.
Compact and Lightweight design
obtained by minimizing motor weight,
with a newly designed tool-structure
Operation mode change lever
positioned on the bottom of gear housing
for reduced possibility of breakage
