Cutter picks are vital in mining and construction. While coal mining picks and roadheader (tunnelling) picks look similar, they're built for very different jobs.

Purpose & Material:

·Coal Picks: Cut softer coal (hardness f≈0.8-4.0). Focus: high coal recovery, less fragmentation.

·Roadheader Picks: Tackle hard rock & complex ground (hardness f≈4-8+). Need: extreme impact resistance & durability.

Design Focus:

·Coal Picks: Sharper tip, lightweight for cutting efficiency.

·Roadheader Picks: Robust body, reinforced tip for strength & impact absorption.

Wear & Technology:

·Coal Picks: Wear from abrasion; benefit from hard materials & coatings.

·Roadheader Picks: High wear in hard rock. XINDA's picks use cold forging, proprietary alloys, and ultra-wear-resistant coatings, boosting hardness & toughness by 1-1.5x. Proven in F14 grade hard rock, they last 2x longer than traditional picks.

Machine Compatibility:

·Coal Picks (e.g., U47-U170): For shearers/continuous miners.

·Roadheader Picks (e.g., U135, S100-S200): For roadheaders/tunnelling machines.

Conclusion:Coal picks for coal; roadheader picks for rock. Choosing high-performance picks, like XINDA's specialized hard rock solutions, means less downtime, longer equipment life, and better project outcomes.
