Excavator Drum Cutters by TGEC

TGEC builds excavator drum cutters for rock excavation, concrete milling, trenching, profiling, and other jobs that call for precise, controlled material removal. Our lineup includes eight hydraulic drum cutter models sized for machines from 0.7 tons all the way up to 70 tons, with output torque ranging from 1592 to 50495 Nm and cutting drums fitted with 44 to 80 carbide-tipped teeth. As a factory-direct manufacturer, we supply these attachments to equipment dealers, civil contractors, quarry operators, and OEM partners with direct production and sourcing support.

Application Scenarios

Rock excavation and profiling: Mill and shape rock faces in quarry, mining and civil construction projects where controlled excavation is required.
Concrete milling and demolition: Remove concrete structures, road surfaces and bridge decks with precision, with reduced noise and vibration.
Trenching and pipeline work: Cut narrow, precise trenches in rock and compacted soil for utility and pipeline installation where conventional digging is ineffective.
Tunneling and underground cutting: Perform controlled cutting in confined underground and tunneling applications where precise material removal is essential.
Foundation and underpinning: Mill rock and concrete around existing foundations for underpinning, basement excavation and structural modification work.
Controlled material removal: Remove coatings, overlays and damaged material from surfaces with precision, reducing the risk of damage to the underlying substrate.

Machine Compatibility

Final fit depends on your excavator's operating weight, auxiliary hydraulic flow and pressure, pin spacing, pin diameter, and coupler type. Each model has recommended flow and maximum flow specs that need to line up with your machine's auxiliary circuit capacity.

OEM & Bulk Supply

As a direct manufacturer, TGEC supplies excavator drum cutters to equipment dealers, quarry operators, civil contractors, and OEM partners around the globe. We offer dealer and bulk-supply programs based on model selection, order volume, machine specs, and project needs. OEM and private-label arrangements can also be explored based on partner requirements and production feasibility.

Frequently Asked Questions

What types of excavator drum cutting attachments are available?+

TGEC offers one product family of excavator drum cutters — eight models covering 0.7 to 70 ton excavators. Models differ in hydraulic flow, output torque, drum speed, weight and number of cutting teeth, so each one matches a specific excavator class and application, from mini excavator utility work to heavy quarry and tunneling operations.

What is an excavator drum cutter used for?+

An excavator drum cutter is a hydraulic attachment that uses a rotating drum with carbide teeth to shear and mill rock, concrete and compacted material. Unlike a hydraulic breaker that delivers impact force, it produces a more uniform finish with lower noise and vibration. Typical uses include rock profiling, concrete milling, precision trenching, tunneling, foundation underpinning and controlled surface removal.

What is the difference between a drum cutter and a rock grinder?+

In the excavator attachment market, drum cutter and rock grinder refer to the same product — a hydraulic attachment with a rotating carbide-toothed drum for milling rock and concrete. The names vary by manufacturer and region, but there is no meaningful technical difference between them.

How do I choose a drum cutter for my excavator?+

Start with your excavator's auxiliary hydraulic flow and pressure — each model has recommended and maximum flow requirements that must match your machine. Next, check operating weight and lift capacity, since larger models can weigh up to 5200 kg and need stable machines. Then match torque to your material: harder rock and concrete need higher torque, while lighter profiling work suits smaller models. Our team can cross-reference your specs against all eight models to recommend the right fit.

What information is needed before selecting an excavator drum cutter?+

Before recommending a model, we need your excavator make and model, operating weight, auxiliary hydraulic flow range and maximum pressure, mounting dimensions (pin-to-pin spacing, pin diameter, coupler type), the primary material to cut, and the typical application. Note any space or depth constraints. If your machine has a case drain line on the auxiliary circuit, mention it — our team will confirm whether the selected model requires one.
