Roadheader Picks / Tunneling Picks
Roadheader Picks & Tunneling Picks
ENTTU manufactures roadheader picks and tunneling picks for underground excavation, mining roadway development, and tunnel construction. Our carbide-tipped picks combine superior wear resistance, high impact strength, and reliable performance — cutting tool replacement frequency and equipment downtime across abrasive cutting conditions.
Our product range includes conical picks, round shank picks, radial picks, and matching holders, covering different cutting applications and machine configurations. These tools cut effectively through coal, salt, potash, gypsum, ore, and various rock formations.
Whether you need replacement picks for an existing roadheader or customized cutting tools for a specific application, ENTTU supports product selection and OEM manufacturing based on technical drawings, samples, and dimensional requirements.
Technical Advantages of ENTTU Roadheader Picks
1. Excellent Wear Resistance
Premium tungsten carbide tips (WC-Co alloy) with optimized carbide grades and cutting-head geometry deliver longer service life in abrasive rock — fewer pick changes per shift, lower cost per meter advanced.
2. High Impact Strength
Pick bodies are forged from high-tensile alloy steel and heat-treated to a balanced hardness and toughness (HRC 40–50). They withstand impact loading, bending, and premature breakage during continuous excavation.
3. Optimized Cutting Geometry
The self-sharpening cutting profile supports efficient rock penetration and fragmentation, reduces dust generation, and maintains cutting performance as the tool wears.
4. Reliable Pick & Holder Matching
Roadheader picks operate as a complete cutting system. Correct matching between pick, shank, retaining arrangement, and holder ensures secure installation and extended cutting-head life. We review your samples and drawings to identify exact replacements.

Refer to individual product specifications to confirm dimensions. If you cannot find your model, send us your existing pick, drawing, or sample for evaluation.
Applications
- Tunnel construction — metro, railway, highway, and utility tunnels
- Underground roadway development — crosscuts, drifts, ramps, and declines
- Mining drivage — coal-bearing strata and surrounding rock
- Industrial minerals — salt, potash, and gypsum excavation
- Rock excavation — soft to medium-hard and abrasive rock formations
The correct pick design depends on excavation material, rock abrasiveness, machine power, and cutting-head configuration.
How to Select the Right Roadheader Pick
To identify the best pick for your equipment, please provide:
- Machine information — roadheader brand, model, and cutting-head configuration
- Existing pick details — model, drawings, photographs, or a physical sample
- Key dimensions — shank diameter, overall length, head dimensions, retaining-groove dimensions
- Ground conditions — coal, soft rock, hard rock, or abrasive rock, with rock strength data if available
- Operating requirements — current wear problems and expected service life
- Order details — quantity and delivery destination
These details allow us to verify dimensional compatibility and recommend the right configuration.
OEM & Custom Manufacturing
ENTTU supports OEM manufacturing based on customer drawings, samples, and technical specifications. Customization may include pick dimensions, carbide tip geometry, steel body design, and other specified features. We compare your existing sample with the proposed design and confirm all technical details before production.
Frequently Asked Questions
What are roadheader picks used for?
Roadheader picks are cutting tools mounted on the cutting head of a roadheader, used for mechanical excavation in underground mining, roadway development, and tunneling.
What is the difference between roadheader picks and coal mining picks?
Roadheader picks are made for roadheader cutting heads in roadway excavation and tunneling; coal mining picks are made for longwall shearers and continuous miners. The correct type depends on your equipment and working conditions.
Can ENTTU manufacture picks according to drawings or samples?
Yes. We manufacture to technical drawings, physical samples, and confirmed dimensional requirements.
How do I confirm a replacement pick fits my machine?
Provide the machine model, existing pick model, holder information, photographs, and key dimensions. Shank diameter alone is not sufficient — the retaining arrangement and installation dimensions must also be checked.
How do ground conditions affect pick selection?
Rock strength, abrasiveness, mineral composition, and impact loading all influence wear and performance. Sharing the excavated material details and observed wear patterns helps us recommend the most suitable pick.
