Dual-Damper System DDS
FRD has developed Dual-Damper System, a first in the industry. For maximum energy transfer, active DDS minimizes return of shock waves by keeping the bit firmly against the rock at all times during drilling. Active DDS minimizes percussion energy loss and, by optimizing the overall feed force, reduce hole deviation. An additional benefit is greatly improved life of drilling accessories. (U.S. PATENT No.5,896,937)

Compact Valve Design
A compact shuttle valve minimizes loss of oil pressure and maintains total power output of the drifter.

Reverse Percussion System (Optional)
The Reverse Percussion System (RPS) makes it easier to free a stuck rod. A substantial increase in extraction force allows the field proven RPS (optional) to remove stuck rods quickly. Thanks to advanced hydraulic and pneumatic technology, out put energy can be transferred to each component with minimum power loss. These systems support high productivity.


Powerful CAT® engine is fully compliant with Tier3 / Euro Stage-3 emission control.

Thanks to advanced hydraulic and pneumatic technology, out put energy can be transferred to each component with minimum power loss. These systems support high productivity.

Position II : 1.600 min-1
Position III : 1.800 min-1
Position IV : 2.000 min-1
Position V : 2.200 min-1

Newly Designed Economy Mode

By using power-saving switch, fuel consumption is reduced during “light” work conditions. (Maximum 30 % reduction on previous models.). While drilling, Engine speed can be adjusted lower than power mode. Engine speed can be selected from one of following speed.

“Light” Work
According to Rock Condition
“Hard” Work
1.600 min-1
1.800 min-1
2.000 min-1
2.200 min-1
New Economy Mode

For the hole cleaning, Engine speed automatically increases up 2.200 min-1. As a result, even in economy mode, you can realize the perfect cleaning as power mode does.

High capacity Compressor & Dust Collector

High capacity Compressor & Dust Collector

High-output compressor increase flushing air, provides faster drilling and decreases bit wear. Upgraded dust collector has higher suction capacity than previous models. Dust collector includes an effective pre-cleaner (optional) to reduce escape of drilling dust. An optional dust suppression system is available for diffi cult drilling conditions.

High capacity Compressor & Dust Collector
HCR1200-DSIII is provided with operator proven “triple plus one” drill control design. FRD experienced operators will perform their skill level from day one, with triple hydraulic drill control and one air control lever layout. No learning time is required.

Anti-jamming Device

Anti-jamming Device
An anti-jamming device optimizes the drilling condition for a variety of rock types, thus offering extended bit and rod life, and consequent reduction in running cost.

Mode Selector

Mode Selector
A mode switching hydraulic circuit performs switching between N mode for homogeneous rocks and H mode for slant joints, thus enabling safe and speedy drilling.

Heavy duty undercarriage & oscillating

Heavy-duty track flames provide strength and durability. One-piece drive sprockets are manufactured with hardened surfaces for longer life. Heavy-duty track links are forged from high-manganese alloy steel, and pins and bushings are induction-hardened.Standard full track guards protect undercarriage, Track tension can be adjusted easily with a grease gun. The entire machine oscillates up-down 7.5 degrees total 15 degree to maintain machine level. And right and left tracks equalize 20 degrees to negotiate uneven ground.

New design comfort cab

New design cab provides large windows at the front and on the right side to maximize operator visibility. Cab is air conditioned and pressurized with air filters to keep out dust.
