An excavator metal saw is a hydraulic-powered excavator attachment designed to be mounted on 6-40 ton carriers. It uses a rotating blade embedded with industrial diamonds or carbide teeth to cut through rock, concrete, rebar, and steel. These attachments turn standard excavators into precise cutting machines for demanding jobs like bridge demolition, tunnel excavation, and quarrying. Four models cover blade sizes from 800mm to 1800mm. Torque reaches 3100 N · m at 40MPa working pressure. Fixed and 360° rotation options are available.

How Does an Excavator Rock Saw Work? Rock Cutting Process
An excavator rock saw works by using the excavator’s hydraulic system to spin a diamond or carbide blade at high speed. The motor delivers torque from 600 N · m to 3100 N · m depending on the model. The blade mounts on a pivot arm. The operator controls cut depth by tilting the arm. Here is the step-by-step process:
- Step 1: Position. The operator aligns the blade with the cut line. The 360° rotation option lets you adjust without moving the excavator.
- Step 2: Start the motor. Hydraulic flow drives the motor. Blade speed ranges from 1-650 r/min continuously. Maximum speed reaches 600-1100 r/min.
- Step 3: Begin the cut. The operator tilts the arm to lower the blade. A typical cut goes 300- 650 mm deep in one pass.
- Step 4: Monitor pressure. A gauge shows hydraulic pressure. Working pressure stays at 40MPa. The operator adjusts feed speed to match material hardness.
- Step 5: Cool the blade. Water sprays onto the blade during cutting. This cools the diamond segments and suppresses dust.
- Step 6: Complete the cut. The blade stops spinning when the cut finishes. The arm lifts the blade out. The excavator moves to the next cut.
The process takes 2-5 minutes per cut depending on material. That is 40-60% faster than breaker-and-grind methods. No secondary breaking needed. No vibration damage to nearby structures.

Excavator Rock Saw for Sale: How to Choose the Right Model?
An excavator rock saw for sale must match your carrier and your cutting needs. Start with excavator weight. The YSJ04 fits 6-12 ton machines. The YSJ10 fits 30-40 ton machines. Using a larger saw on a small carrier risks tipping. Using a smaller saw on a large carrier wastes capacity.
Next, check blade size. The 800mm blade cuts shallow trenches. The 1800mm blade cuts deep walls. Choose based on your maximum cut depth.
Then, consider rotation. Fixed saws cost less and weigh less. They work for straight cuts. 360° rotation saws let you cut at any angle without repositioning the excavator. That saves time on complex jobs.
Check hydraulic flow. The YSJ04 needs about 40-60 L/min. The YSJ10 needs 120-150 L/min. Match your excavator’s auxiliary circuit.
Finally, look at torque. The YSJ10 delivers 3100 N · m. That power cuts through hard rock and thick rebar. The YSJ04 delivers 600 N · m for lighter work.

Excavator Rock Cutting Attachment: 6 Applications
An excavator rock cutting attachment works in many industries. Here are six common applications.
- Tunnel excavation. Cut precise openings in rock walls. The 360° rotation reaches tight angles. One contractor in Switzerland cut 200 meters of tunnel with a YSJ08.
- Bridge demolition. Cut concrete decks and piers. The diamond blade slices through rebar. A Texas crew cut 14 expansion joints in 7 days with a YGJ06.
- Quarrying. Extract dimensional stone. The 1800mm blade cuts clean blocks. A quarry in Italy uses two YSJ10 units daily.
- Foundation work. Cut trenches in rocky ground. The YSJ04 fits compact excavators for residential jobs.
- Pipeline construction. Cut rock for trenching. The attachment works in confined spaces. An Australian pipeline crew used a YSJ08 to cut 12km of rock.
- Demolition. Remove reinforced concrete walls. The saw cuts straight lines without vibration. A German contractor reduced wall removal time by 40%.

Rock Saw Attachment Price: 5 Factors That Affect Your Investment
Rock saw attachment price depends on five main factors. Knowing them helps you budget and compare quotes.
- Model size. Larger models use more steel and bigger motors. The YSJ10 costs more than the YSJ04. The price scales with capacity.
- Rotation type. Fixed saws cost less. 360° rotation adds a hydraulic motor and gear ring. That adds $2,000-$4,000 to the price.
- Blade type. Diamond blades cost more than carbide. Diamond lasts longer in hard rock. Carbide suits concrete and asphalt.
- Hydraulic requirements. Higher flow and pressure need stronger components. That increases cost. But it also increases cutting speed.
- Supplier type. Factory-direct saves 15-20% versus dealers. YG Machinery sells direct from our Zhengzhou factory. No middleman markup.
Spare parts and warranty also affect total cost. Ask for a quote that includes a spare blade and seal kit.

What Do Customers Say?
- USA – Bridge Contractor (YGJ06). “We had 14 expansion joints to cut on a 1200mm thick bridge deck. The old breaker method took 4 hours per cut plus 2 hours of grinding. With the YGJ06, each cut dropped to 2.5 hours. The blade stayed sharp through rebar and hard aggregate. The grinding step disappeared. We finished the whole job 7 days early and saved $12,000 in labor. We’ve since bought a second unit for our Dallas crew.” — Project Manager, Texas
- Germany – Demolition Company (YSJ08 with 360° Rotation). “We were removing reinforced concrete walls in a downtown Munich building. Vibration was a major concern because of adjacent structures. The YSJ08 cut clean lines without any hammering. The 360° rotation let us cut at angles without moving the excavator. We reduced wall removal time by 40%. The remote control kept our operator clear of falling debris. No complaints from neighbors. We now use it on every interior demolition job.” — Site Foreman, Munich
- Australia – Pipeline Project (YSJ10). “We needed to cut 12km of trench through sandstone and shale. The YSJ10 on our 35-ton excavator delivered 3100 N · m of torque. It never stalled, even in the hardest sections. We cut 200 meters per day – double our original estimate. The 1800mm blade handled the depth in one pass. We finished the trench 2 weeks early. The fuel savings alone covered the attachment cost. We’ve ordered two more units for our Queensland operations.” — Equipment Manager, Queensland
These contractors report faster cuts, lower labor costs, and consistent results. The attachment pays for itself through reduced grinding, fewer man-hours, and faster project completion.
